Sunlight fuels photosynthesis here on Earth, which in turn sustains all life on our planet. But how would this crucial process work on planets which orbit fainter stars?
We know UV radiation isn’t good for us, but can it hold back all forms of life?
A combination of infrared spectrograph and laser frequency comb provides unprecedented precisions in the hunt for habitable planets around nearby, cool stars.
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.
