Which stars are the most hospitable for life? This lecture examines the
factors affecting the habitability of stars, with a goal of
understanding where we should search for life-bearing planets. We will
do this by generalizing the idea of a Habitable Zone developed for the
Sun back in Lecture 30. In this context, we find that the best places
to search for life would be rocky planets in the habitable zones of
low-mass main-sequence stars. There are a number of caveats we will
discuss - tidal locking, stellar flares, and UV radiation - and
limitations to the approach, but it seems to be a good place to start
our search. Recorded live on 2009 Nov 13 in Room 1005 Smith Laboratory
on the Columbus campus of The Ohio State University.
