Coronal Solar Magnetism

Frontiers eBook on Coronal Magnetometry now available for free download


Magnetism defines the complex and dynamic solar corona. It determines the magnetic loop structure that dominates images of the corona, and stores the energy necessary to drive coronal eruptive phenomena and flare explosions.

An Explanation of Remarkable Emission Line Profiles In Post-Flare Coronal Rain

Intensity profiles of the Mg II h and k lines
Tuesday, August 8, 2017

We study broad red-shifted emission in chromospheric and transition region lines that appears to correspond to a form of post-flare coronal rain.

MHD Simulations of the Eruption of Coronal Flux Ropes under Coronal Streamers

MHD simulations
Thursday, July 20, 2017

Using three-dimensional magnetohydrodynamic (MHD) simulations, we investigate the eruption of coronal flux ropes underlying coronal streamers and the development of a prominence eruption.

Magnetic Nulls and Super-radial Expansion in the Solar Corona

Coronal pseudostreamer magnetic topology
Monday, May 1, 2017

Magnetic fields in the sun's outer atmosphere, the corona, control both solar-wind acceleration and the dynamics of solar eruptions.

DKIST: Solar Physics in Service of Society

Phil Judge, Claire Raftery, Sarah Jaeggli

Philip Judge, Senior Scientist at HAO, Claire Raftery, Director of Education and Outreach at NSO HQ in Boulder, and Sarah Jaeggli, Assistant Astronomer at the NSO's Daniel K Inouye Solar Observatory in Maui were guests on KGNU public radio in Boulder, CO.

Lisa Upton

Lisa is a Visiting Scientist here at HAO since September 2014 and also is currently working for Space Systems Research Corporation. In the spring of 2017, Lisa will begin a NSF postdoctoral fellowship at HAO, working as a collaborator with the dynamo group.
