Context: Scientists have discovered a rare quadruple star system in our Milky Way galaxy called UPM J1040−3551 AabBab. It is the first known system where two brown dwarfs orbit around two red dwarf stars.

About UPM J1040−3551 AabBab:

• What it is?

• A unique 4-star system: 2 Red dwarf stars (small, common stars that shine faintly but live very long). 2 Brown dwarfs (objects between stars and planets, called “failed stars” because they cannot fuse hydrogen like stars).

• 2 Brown dwarfs (objects between stars and planets, called “failed stars” because they cannot fuse hydrogen like stars).

• Key Features:

• Red dwarfs are bright enough to be studied → scientists can estimate the properties of the faint brown dwarfs. Brown dwarfs are about the size of Jupiter, but much heavier. Such systems are extremely rare → chances of low-mass brown dwarfs having companions is less than 5%.

• Significance:

• First of its kind → never before seen configuration. Helps study brown dwarfs, which are very hard to detect because they are cold and faint. Provides insight into how stars and planets form in space. Improves knowledge about the distribution of mass in the universe (important in studying dark matter). Acts as a natural laboratory → since all 4 formed together, scientists can compare their age, temperature, and composition accurately.
