Latest Brown dwarf Stories
New research has found the two oldest brown dwarfs in the galaxy, and they have a somewhat unexpected property: they move extremely fast.
Two years ago NASA scientists revealed a new class of stars, dubbed ‘Y dwarfs’, thought to be about as warm as the human body. However, newly published research indicates that these cold stars are probably a bit warmer than the boiling point of water.
Using data obtained from a NASA satellite, a Pennsylvania State University astronomer has identified the closest solar system to be found within the past 97 years.
There are small subsets of stars among the hundred billion in the Milky Way called ultra-cool dwarfs, which have a temperature below 2500 Kelvin.
By using the Hubble and Spitzer space telescopes, NASA officials say they have managed to complete the most detailed weather map to date for the cool, planet-like stars known as brown dwarfs.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that the outer region of a dusty disc encircling a brown dwarf contains solid grains like those found in denser discs of newborn stars.
New research from the University of Washington and Leibniz Institute for Astrophysics, Potsdam, hints that planets orbiting white or brown dwarfs will prove poor candidates for life.
The search for planets around other stars might have gotten a little easier now that a Lowell astronomer and her colleagues have developed a set of directions, per se, to aid others in the hunt for exoplanets.
Astronomers are getting to know the neighbors better. Our sun resides within a spiral arm of our Milky Way galaxy about two-thirds of the way out from the center. It lives in a fairly calm, suburb-like area with an average number of stellar residents.
- Any of various tropical Old World birds of the family Indicatoridae, some species of which lead people or animals to the nests of wild honeybees. The birds eat the wax and larvae that remain after the nest has been destroyed for its honey.
