Princeton Plasma Physics Laboratory (PPPL) Theory Seminar - ADDED

Part 1: Understanding coronal magnetic activity in stars is of interest for its connections to the basic physics of magnetic field amplification, reconnection and particle acceleration, and for secondary implications of determining stellar ages and influences on planetary habitability. Why the stellar magnetic activity is observed to increase with stellar rotation for slow rotators but becomes independent of rotation for fast rotators has been a long-standing puzzle. I will discuss how incorporating two principles of modern magnetic dynamo theory into traditional thinking shows promise toward explaining this puzzle. Part 2: I will describe a mechanism and predictions from a two-stage scenario for solar/stellar flare particle acceleration.
