EXCERPT: Two phenomena known to inhibit the potential habitability of planets — tidal forces and vigorous stellar activity — might instead help chances for life on certain planets orbiting low-mass stars, University of Washington astronomers have found.
In a paper published this month in the journal Astrobiology, UW doctoral student Rodrigo Luger and co-author Rory Barnes, research assistant professor, say the two forces could combine to transform uninhabitable “mini-Neptunes” — big planets in outer orbits with solid cores and thick hydrogen atmospheres — into closer-in, gas-free, potentially habitable worlds....
