Meeting Summary March 2002

Speaker of the month - Dr Luisa Rebull - CALTECH
Spinning Teenage Stars video (60 minutes)

Rotation of young stars--less than 5 million years old--is key to our understanding of the formation of stars and planetary systems. Without rotation, stars don't have magnetic fields, and without magnetic fields, the Sun would be as boring as most people think it is! After studying about 8000 young stars, we've found 300 new periodic variable stars in Orion and 200 new periodic variable stars in NGC 2264. These stars are all about the same mass as the Sun, but much younger. We find stars with rotation rates ranging from values similar to the Sun to 100 times faster! I will review our current understanding of how we get a planetary system out of a giant cloud of gas and dust, and how rotation might play a role.
