Recently, astronomers looking for potentially habitable worlds have
targeted red dwarf stars because they are the most common type of star, comprising 80 percent of the stars in the universe.
Not exact matches
Potential
targets include planets orbiting TRAPPIST - 1, a
red dwarf star just 40 light years away.
That's a happy conclusion, given that
red dwarfs are the most common stars in the galaxy and also the easiest
targets for ground - based telescopes.
After a workshop on
red dwarfs in 2005, Jill Tarter of the SETI Institute — a leading thinker on alien life — and her colleagues published an analysis that convinced many researchers that
red dwarfs are worthy
targets for Earth hunters.
The new survey will pick
targets from a list of about 70,000
red dwarfs compiled by Andrew West at Boston University, and will listen to the stars in radio frequency bands between 1 and 10 gigahertz.
TESS's primary
targets are
red dwarf stars, the most common stars in our neighborhood.
«We will also
target a small number of
red dwarf stars (such as Barnard's star which was discovered by Vanderbilt's first astronomer) because these are the stars nearest to us.
Star B, a orange -
red dwarf with a relatively calm chromosphere and acoustic p - wave mode oscillations, is an easier
target for detecting wobbles from terrestrial planets, possibly within only three years of «high cadence» observations for a 1.8 Earth - mass planet (more from New Scientist and Guedes et al, 2008).
Star B, the chromospherically calmer, orange -
red dwarf, is an easier
target for detecting wobbles from terrestrial planets, possibly within only three years of «high cadence» observations for a 1.8 Earth - mass planet (more from New Scientist and Guedes et al, 2008).

target for TESS.
