Powerful Winds of Magnetic Massive Stars
Asif ud-Doula, PhD
Associate Professor of Physics, PSU Worthington Scranton
Massive stars (at least eight times as massive as the Sun) possess strong stellar winds driven by radiation. An increasing number of these massive stars have been confirmed to have global magnetic fields. Such magnetic fields can have significant influence on the dynamics of these stellar winds which are strongly ionized. Such interaction of the wind and magnetic field can generate copious amount of X-rays, they can spin the star down, they can also help form large scale disk-like structures. In this presentation I will discuss the nature of such radiatively-driven winds and how they interact with magnetic fields.
MegaMeet scheduled for May 26, 27, 28
Since both of our Pulpit Rock events were rained out in 2016, we decided to improve our odds this year by starting earlier. So our "Plan A" for MegaMeet this year is for the weekend of May 26! Watch this space and the Observer for more details.
The 2017 Astroimaging Calendar is available! Copies will be available at the meeting for $20.00 each.
Also, don't forget that it's time to renew your membership! You can renew at the General Meeting, or at any time by downloading the renewal form here and sending it in with your dues.
