8/28/2014 Seminar – From balloons to the volcano: a journey into high spatial resolution solar physics

Speaker: V. Martinez Pillet (NSO)
Date: Sunday, Aug 28, 2022
Time: 4:00pm
Location: SPSC W120

Seminar Abstract:

The spatial resolutions and sensitivities achieved in today’s solar observations are still far from where the physics of the Sun indicate they need to be. Present day efforts concentrate in 1m-class telescopes that are becoming available, including the balloon-borne SUNRISE telescope. In the future, the NSO-led 4m aperture Daniel K. Inouye Solar Telescope (DKIST, under construction in Maui) will provide unprecedented capabilities. I will present the state-of-the art measurements obtained with the 1m SUNRISE telescope during the 2009 polar flight and discuss the implications for the DKIST project. In particular, I will address in some detail what our current understanding of the origin of the quiet sun magnetism is —including the possibility that it is generated by a turbulent dynamo— and how DKIST can help us solving this problem.
