From Thermal Instability to Coronal Rain – Online Talk by Professor Ramon Oliver
Seminars
On March 8, at 17:00, Professor Ramon Oliver will deliver a speech titled “From thermal instability to coronal rain.” The event is part of the ongoing online seminar series hosted by the Space Research Center at the Department of Astronomy and Astrophysics, Ilia State University (ISU).
This seminar will introduce the phenomenon of coronal rain, which manifests itself by the sudden appearance of cold material in the otherwise hot solar corona. The speaker will overview linear waves in a fluid, explaining the mathematical method to study such waves in an infinite and homogeneous medium. He will present the wave properties that arise when the heat gain and loss terms relevant to the solar corona are considered. This will allow him to discuss thermal instability, which can lead to the formation of cold condensations. Finally, he will connect coronal rain and thermal instability.
