Subject:          [Mas] This Thursday: Roberta Humphreys
   Date:          Tue, 1 Feb 2005 21:19:38 -0600
   From:          Michael Koppelman 

I'm sure a more general announcement of the upcoming meeting will be 
forthcoming, but I want to make sure everyone knows that Dr. Roberta 
Humphreys from the University of Minnesota will be speaking at the 
monthly meeting this Thursday at 7pm at the Science Museum of 
Minnesota.

Dr. Humphreys is a very well-known astronomer. Among many milestones in 
her career I'll mention a couple: she did a lot of work with Allan 
Sandage on M33, some of which is documented in the book "Lonely Hearts 
of the Cosmos". She, along with her husband Kris Davidson, discovered 
the "Humphrey-Davidson Limit" -- a stability limit on massive stars. 
She is also an expert on massive stars and Eta Carinae.

She is also on the Space Telescope Institute Council and is an
Associate Dean for Academic Affairs (I.T.) at the UofM.

Her talk Thursday will cover, in her words:

I'll talk about some of the cool hypergiants I've been
working on over the past few years. The data includes some interesting
images from HST of VY CMa, IRC+10420, and NML Cyg and I can include
bright stars like rho Cas which is a good target for amateurs. VY CMa is
also good for amateurs with its visible nebula. And I'll mention Var
A! So my title will be "Stars on the Edge".
