Astronomy Cast Ep. 155: Dwarf Stars

The 365 Days of Astronomy

About

From September 14, 2009.

We think we live near an average star, but that’s not the case at all. Compared to most stars in the Universe, the Sun is a giant! Let’s look at the small end of the stellar spectrum, to stars with a fraction of the size and mass of our own Sun. There are many ways that a star can get small, and they lead dramatically different lives and deaths.
