which monitors two thousand red dwarf stars for transiting planets. The planet was targeted next for follow-up observations to characterize its atmosphere.
and his team used a technique called gravitational microlensing to study a binary system with two red dwarfs small stars that are dimmer than the sun. The distance between the stars is about 10 to 15 times that of Earth
But this discovery argues that yes indeed at least in this system of two red dwarfs you can form planets at these sorts of longer distances says Gaudi.
The#study detailed the prevalence of these planets orbiting red dwarf stars and found#that about 15 percent have Earth-size planets within habitable zones.
#Red dwarfs#are one-third the size and one-thousandth as bright as the sun. But in this week's PNAS Online Early Edition a team of researchers from#University of California at#Berkeley released a study that looks at how common Earth-size planets
These stars'surface temperatures range from just a bit hotter than the sun's 5778 Kelvin to as cool as 4100 Kelvin all of which are hotter than the M-class red dwarfs studied previously.
