4042 20190131131913.0 SEMIN-2019-0011 West, Matthew Basic Solar Physics Seminars (12/13) - The Coronal heating problem 2018 2018-05-09 The visible surface of the sun has a temperature of around 6000K. Surprisingly, the overlying Solar atmosphere (the solar corona) is found have a temperature 200 to 500 times higher. For more than a half-century, astronomers have tried to figure out what causes the corona to be so hot, and it is one of the outstanding problems in astrophysics. In this presentation, Matthew West will present the coronal heating problem, a brief history of observations and different mechanisms that have been put forward to answer how the corona is so heated.
