Professor Christian from CSU Northridge has observed and studied the solar corona at observatories around the world.

Damian's current research uses the Dunn Solar Telescope, located in New Mexico in the Lincoln Forest. The goal of the research is to follow up multi-wavelength observations by the Solar Dynamic Observatory and the Hinode ExtremeUltraviolet Imaging Spectrometer of the Sun’s corona during a failed Coronal Mass Ejection (CME).

One of the open questions is, do CME blobs fall faster or slower than gravitational free fall because of magnetic effects? There could be, for example, magnetic pressure impeding flow. In a recent paper, Damian and coworkers reported a kinetic energy ~2 orders of magnitude lower for the main eruption than a typical CME. Detailed studies of failed CMEs and other phenomenon will allow further constraints on the coronal magnetic field and in the larger problem of coronal heating. Damian also recently published in Science a related study of Alfvén waves in the lower solar atmosphere. 

In the near future, Damian is much looking forward to having access to the new 4m solar telescope DKIST that will be going online soon and have a 20 km resolution of the Sun.

Thank you Damian for your informative visit!
