Feature presentation: “What if our Sun were a red dwarf star?” by Dave Bailey

The W.A.S.’s resident Einstein Dave Bailey explores an alternate universe where our yellow dwarf is replaced with a red dwarf instead. Would life be possible? What would the solar system look like?

The book, “Rare Earth”, was written by two professors who believe that we humans might be the only intelligent creatures in the entire Milky Way Galaxy. I myself believe there are intelligent species on many other planets. But I have to answer Enrico Fermi who asked, “Where are they?” My answer is, “Most of them live in red dwarf star systems.” I’m guessing there might be 100,000 of these inhabited stellar systems in our galaxy. In this talk, I will explore the astrophysics, both stellar and planetary, in such red dwarf systems. Perhaps a biologist, hearing my talk, might be inspired to write another talk, which would explore how such a red dwarf star and planet could foster a species at least as smart as our own.
