MIT astronomers catch a star in a feast that could last billions of years
MIT astronomers have identified a unique star system where a low-mass star is slowly consuming a brown dwarf over a period of billions of years. This discovery provides a rare look at a long-term, stable feeding process rather than the typical violent engulfment seen in other systems.
Why it matters
Understanding these stellar interactions helps astronomers better predict the long-term evolution of planetary systems and stellar life cycles.
Astronomers have discovered an unusual star system about 300 light-years from Earth where a small star is gradually consuming a nearby brown dwarf. Instead of swallowing its companion in one dramatic event, the star is steadily pulling material from it, creating a cosmic feeding process that could continue for billions of years.
Most planets, including Earth, travel around their stars in relatively stable orbits. But these peaceful arrangements can sometimes end violently. If a planet ventures too close to its host star, the star's gravity can drag it inward and eventually engulf it.
Scientists have observed many planetary systems with stable orbits, along with a small number of stars caught rapidly swallowing their planetary companions. Now, researchers have identified something that falls between those two extremes.
