Habitable Evaporated Cores
Seattle WA (SPX) Jan 29, 2015
I recently published a paper in Astrobiology that shows that it is possible to form Earth-mass potentially habitable planets from mini-Neptunes that migrate into the habitable zones of mid- to late M dwarf stars. Click here to see the poster I presented at the March 2014 EBI (Exoplanets, Biosignatures and Instruments) conference in Tucson, AZ. Also, check out the abstract from a talk I gave at AAS. Low mass M dwarf stars make up nearly three-quarters of the stars in our galaxy. Because they are sm ... read more
