brown dwarf

The exoplanet survey discovered only one previously unknown planet -- 51 Eridani b, nearly three times the mass of Jupiter -- and one previously unknown brown dwarf -- HR 2562 B, weighing in at about 26 Jupiter masses.

According to the team behind the detection, the object was seen all the way back in 2016, but during that time, scientists thought it was a massive brown dwarf - objects that are too big to be called planets but too small to become a small star.

"Had this star formed with only a slightly lower mass, the fusion reaction of hydrogen in its core could not be sustained, and the star would instead have transformed into a brown dwarf."

In May, a team of astronomers announced that they have discovered a small substellar "failure" called a brown dwarf that once had been a true star--before it was ravaged by its hungry white dwarf companion.

Today, the coolest known starlike orb is a brown dwarf discovered last year.

ISLAMABAD -- Astronomers have discovered the first aurora outside our solar system, around a brown dwarf about 18 light years away from Earth and up to 10,000 times more powerful than any previously seen.

The astronomical aurora affected the cloudy atmosphere surrounding the "brown dwarf " LSR J1835+3259.

Washington, Apr 26 ( ANI ): NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what looks like the coldest "brown dwarf" known-a dim, star-like body that, surprisingly, is as frosty as Earth's North Pole.

They peered out into space at a brown dwarf named ISO-Oph 102.

Solar system planetary scientists, brown dwarf and exoplanet observers and theoreticians, molecular spectroscopists, and instrument specialists discuss methods and findings in the composition of atmospheres around planets beyond the solar system.

Scattered among the galaxy are brown dwarf stars, capable of producing energy to heat colonizing stations and power starships.
