We know UV radiation isn’t good for us, but can it hold back all forms of life?
We need to know the radii of M-dwarfs to study their exoplanets, and the models aren’t much help.
This week about 500 astronomers met in Boston, MA for the 20th Cambridge Workshop on Cool stars, Stellar Systems, and the Sun (Cool Stars) meeting.
If we don’t understand starspots, we won’t understand exoplanet atmospheres.
Three more potentially habitable planets that are also relatively nearby have been discovered! If they are really in their habitable zone, they should have water today, but only if they did not lose it all early on in their lifetimes. Could any of these planets have retained their water supply?
On using photometric data from Kepler to study starspots, and to measure differential rotation rates.
