Wednesday 19th of January Ramon Oliver will present the HAO Colloquium called The Hitchhiker’s Guide to Coronal Rain.
Title: The Hitchhiker’s Guide to Coronal Rain
Author: Ramon Oliver
So you think that rain drops cannot be as large as 200 km? Then welcome to the solar corona, where such big droplets exist! They appear out of the blue at the top of coronal loops and then rain down on the Sun’s surface, bringing with them an estimated mass up to a few million kg/s along each individual loop. In this talk I will present the main facts about coronal rain and will explain why it is a super ecologic phenomenon: coronal rain material is recycled as it continuously evaporates from the chromosphere, condenses and rains down, in a cycle that repeats with a period of a few hours.
