What makes this system particularly fascinating is the extreme proximity of the first two stars and their relationship with the third. Let's break down each component to understand what makes this system so unique.  The Primary Pair: A Dance of Giants and Dwarfs At the heart of this system is something that defies ordinary stellar relationships - a white dwarf (AA) and red dwarf (AB) locked in an incredibly tight orbit. 
The White Dwarf (AA): A Dense Stellar Remnant This white dwarf is a monster compared to typical white dwarfs:
To put this in perspective: this white dwarf packs more mass than our Sun into a sphere roughly the size of Earth. If you could somehow stand on its surface (you absolutely couldn't), you'd be crushed by gravity over 200,000 times stronger than Earth's.
The white dwarf's spectral classification as DZ2.9 indicates it contains heavy metal absorption lines in its spectrum, suggesting it has accreted metal-rich material - most likely from its companion.   The Close Red Dwarf Companion (AB): Living Dangerously The companion red dwarf is equally remarkable: For comparison, Mercury orbits the Sun at about 58 million km. This red dwarf is orbiting over 6 times closer to its companion than Mercury is to our Sun! The most astonishing aspect is their orbital period - just 4.93 days. These two stars complete a full orbit around each other in less than a week! For perspective, Mercury takes 88 days to orbit the Sun. The extreme density of this red dwarf suggests it may have lost its outer layers to the white dwarf, leaving behind a more compressed stellar core. Its M8.9V spectral classification places it among the smallest, coolest main sequence stars.   The Outer Red Dwarf (B): The Third Wheel Circling around this intense inner pair is a second red dwarf:
This star's orbit takes 1.35 years to complete - slightly longer than Earth's year. Unlike the synchronized rotation of the inner pair, this outer dwarf spins rapidly on its axis, completing a rotation in just over 5 hours!
With a spectral classification of M9.8V, this is nearly at the boundary between red dwarfs and brown dwarfs, making it one of the coolest stars that can still sustain fusion.  The System's Architecture The arrangement of this triple system is hierarchical:
The luminosity of the entire system is dominated by the white dwarf, despite its small size. The combined system shines with the power of 4.57 million Suns - primarily because of the white dwarf's extreme surface temperature.
The Physics of This Bizarre System This system presents several fascinating physical phenomena: 1. Extreme Tidal ForcesThe inner pair experiences tremendous tidal forces. The white dwarf's immense gravity likely causes significant distortion in the red dwarf companion. This interaction would create:
The red dwarf companion orbits well within the white dwarf's Hill sphere (303,614 km), meaning it's completely dominated by the white dwarf's gravity. 2. Accretion ActivityThe white dwarf is actively accreting matter at a rate of about 2.18×10^-11 solar masses per year. This comes from its red dwarf companion, which is slowly being cannibalized by its dense neighbor.
To visualize this rate: the white dwarf pulls in approximately 1.3 million tons of material every second from its companion - equivalent to a small mountain on Earth being transferred every second. 3. Stellar Evolution MysteryWith an age of approximately 6.6 billion years, this system is older than our solar system. The presence of such a massive white dwarf suggests the original star was extremely large before it shed its outer layers.
Based on its mass, the progenitor star of the white dwarf likely had a mass of 7-8 solar masses. Such a star would have lived only about 50-100 million years before becoming a white dwarf. 4. Orbital ResonanceThe system exhibits a 1:1 orbital resonance between the inner pair (AA) and the outer star (B). This suggests the system has achieved a state of dynamic stability despite the extreme conditions. Exploration Potential: What Would We See? If we could somehow visit this system, the views would be spectacular: From the outer red dwarf (B), you would see the inner binary sometimes appearing as a single bright point and at other times as two distinct stars, depending on their orbital position. The white dwarf would appear blindingly bright despite its small size, while its red companion would appear as a large, dim reddish disk. From the inner red dwarf (AB), the white dwarf would dominate the sky - appearing not as a disk but as an intensely bright, almost point-like source that would still illuminate the entire star like perpetual daylight. The tidal forces would likely create massive "stellar quakes" throughout the red dwarf's body.
The radiation environment near the white dwarf would be extreme, with high levels of ultraviolet and potentially X-ray emissions making direct exploration challenging for any hypothetical spacecraft. so this is video of white dwarf orbit! this are orbits of white dwarf and its close red dwarf now you can see all three stars orbits Bizarre Features That Defy Expectations 1.The massive white dwarf: At 1.18 solar masses, this white dwarf approaches the Chandrasekhar limit (about 1.4 solar masses), beyond which white dwarfs become unstable. It's rare to find white dwarfs this massive, as they typically form from stars up to 8-10 solar masses, which usually result in white dwarfs around 0.6-0.7 solar masses. 2.The ultra-close binary: The proximity of the inner pair is extreme even by astronomical standards. The red dwarf orbits at just over 8.5 million km from the white dwarf - well within the white dwarf's Roche limit for satellites (695,814 km). This suggests the red dwarf itself is very dense and compact to resist tidal disruption. 3.Synchronized rotation: Both inner stars are tidally locked to each other, rotating in exactly the same period as their orbit (4.928 days). This is strong evidence of their intense gravitational relationship. 4.Metallicity contrasts: The three stars show dramatically different metallicity values. The white dwarf has a remarkably high metallicity ([Fe/H] = 1.548), the inner red dwarf has a slightly elevated value ([Fe/H] = 0.029523), while the outer red dwarf is metal-poor ([Fe/H] = -0.15287). This suggests they may have formed in different regions of their parent molecular cloud, or that the white dwarf has contaminated its close companion through mass transfer which is most probable! 5.Similar radius of red dwarfs: Despite their different masses, both red dwarfs have identical radius (42,062 km). This could indicate they've been shaped by similar forces despite their different positions in the system The System's Past and Future Evolutionary History This triple system likely began as three separate stars that formed together about 6.6 billion years ago. The most massive of the three evolved quickly, expanding into a red giant before shedding its outer layers to form the white dwarf we see today. During this process, the closest companion (now the inner red dwarf) would have been engulfed by the expanding giant star, causing it to lose orbital energy and spiral inward to its current tight orbit. This process, known as common envelope evolution, explains the current ultra-close configuration. Future Prospects Type Ia supernova potential: If the white dwarf continues accreting material from its companion and approaches the Chandrasekhar limit of 1.4 solar masses, it could eventually explode as a Type Ia supernova - one of the most energetic events in the universe. Continued stellar vampirism: The more likely near-term scenario is continued accretion, with the white dwarf slowly consuming more material from its red dwarf companion. Binary merger: If orbital decay continues, the inner red dwarf might eventually merge with the white dwarf, potentially creating a massive flare or nova-like event. System reconfiguration: Any significant change to the inner pair could destabilize the orbit of the outer red dwarf, potentially ejecting it from the system entirely. Comparative Astronomy: How Unique Is This System? While triple star systems aren't uncommon (making up roughly 10% of stellar systems), this particular configuration is highly unusual for several reasons:
Similar systems include Sirius (which has a white dwarf companion to a main sequence star, though at a much greater separation) and some cataclysmic variable stars, though few combine all the extreme elements seen here. Visual Tour Now i will show you some amazing photos of this system

RS 8513-928-8-5794238-80 represents what might be a relatively brief cosmic arrangement. The white dwarf's active accretion from its companion suggests an ongoing process that will eventually transform the system further.
The proximity of the inner stars, combined with the mass transfer, means we're likely witnessing a system in transition. In astronomical terms, this configuration might be temporary - perhaps leading eventually to:
Whatever its ultimate fate, this triple star system offers a rare glimpse into extreme stellar physics and the diversity of arrangements possible in our galaxy. It reminds us that the universe continues to surprise us with configurations that push the boundaries of what we thought possible.
It also makes us appreciate the relative stability of our own solar system - a place where stars maintain comfortable distances and planetary systems can develop without the extreme conditions found in systems like RS 8513-928-8-5794238-80.
