About this Series

The EAPS Department Lecture Series sponsors talks given by leading thinkers in the areas of geology, geophysics, geobiology, geochemistry, atmospheric science, oceanography, climatology, and planetary science. Lectures take place on Wednesdays from 3:45pm in MIT Building 54 room 915, unless otherwise noted.
This Lecture is part of a Special DLS Series in tandem with the Climate Symposium.
Habitabitlity of M Star Planets: the Next Trillion Years.
Unlke stars such as the Sun, M stars can live practically forever on the Main Sequence and evolve very little during that time. Does that mean that M Star planets that are able to retain or generate a suitable atmosphere have an almost unlimited time for complex life to emerge? In this lecture, I will discuss the factors that ultimately limit the lifespan of habitability for planets orbiting M stars. Many of the same considerations apply to K star planets as well.
