RHESSI Nuggets in April 2020
by Hugh Hudson 22 Apr '20

22 Apr '20

No. 375: “Evidence for a Coronal Shock Wave Origin for Relativistic Protons Producing Solar Gamma-Rays and Observed by Neutron Monitors at Earth,” by Athanasios Kouloumvakos and Gerry Share. Successful modeling of prolonged solar gamma-ray emissions and terrestrial ground-level cosmic-ray events. No. 376: "Phenomena in the unusually long pre-impulsive phase of SOL2011-06-07,” by Marian Karlický, Jana Kašparová, and Robert Sych. A massive and slowly-rising filament eruption reveals important new signatures of the physics. No. 377: "Broad symmetrical Doppler-shifted Fe XXI line profiles,” by Vanessa Polito. It is difficult to explain “evaporation” line profiles by superposition of unresolved flows. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can be found by searching for their SOLyyyy-mm-dd identifier from this home page.
