Speaker: Robert Gehrz – Professor (Minnesota Institute for Astrophysics)
Topic: Stellar Evolution after life on the Main Sequence: Observational studies of Aging Stars
After exhausting their hydrogen fuel during Main Sequence burning, low and high mass stars evolve in distinctly different paths that lead to planetary nebulae and supernova explosions. These paths will be briefly reviewed and selected related optical/infrared observations of aging stars by University of Minnesota Astronomer will be described.
Monthly meetings are open to all – you needn’t be an MAS member to attend. These meetings normally take place the first Thursday of each month at the Fairview Community Center in Roseville (“Great Room”). Monthly meetings start at 7:00 p.m. and last about two hours.
Each meeting features Board member introductions, general announcements, “Better Know a Constellation”, normally presented by a member, main speaker (around 45 minutes duration) and an after-meeting social gathering. Society business is occasionally transacted as needed.
NOTE: Meeting time and / or location sometimes change to take advantage of special program opportunities. Please check the MAS homepage at www.mnastro.org for the latest information regarding the meeting.
