15 new planets confirmed around cool dwarf stars
March 12, 2018, Tokyo Institute of Technology
A research team led by Teruyuki Hirano of Tokyo Institute of Technology's Department of Earth and Planetary Sciences has validated 15 exoplanets orbiting red dwarf systems. One of the brightest red dwarfs, K2-155 that is around 200 light years away from Earth, has three transiting super-Earths. Of those three super-Earths, the outermost planet, K2-155d, with a radius 1.6 times that of Earth, could be within the host star's habitable zone.
The researchers found that K2-155d could potentially have liquid water on its surface based on three-dimensional global climate simulations. Hirano says, "In our simulations, the atmosphere and the composition of the planet were assumed to be Earth-like, and there's no guarantee that this is the case."
