HAO Colloquium Series Presents Rachel Osten, STSI

Stellar Flares: from Plasma Physics on Stars to Space Weather on Other Worlds

The Sun is a star, but of course it is a special one by virtue of its proximity to us; many processes can be studied in detail on the Sun that are inaccessible to study of the remote stars. While it has long been known that stars can produce flaring eruptions, their detailed study had been relegated to a few types of stars considered atypical of potential solar system (and life-bearing planet) hosts. I will review multi-wavelength evidence from stellar studies that cements a physical connection with solar flare processes. Next, I will describe recent results on stellar flares, which probe the extremities of these events and discuss how they can be used to give context to processes bounding solar flare properties. Finally, I will discuss how these studies can give insight into space weather on other worlds, as astronomers expand the realm of potentially habitable worlds.
