164. Magnetoseismology for the solar corona: from ~10 Gauss to coronal magnetograms

Zihao Yang (Peking University)

Session 3 - Fundamental Plasma Processes in the Solar Atmosphere: Magnetic Reconnection, Waves, Emission, Particle Acceleration

Poster

Magnetoseismology, a technique of magnetic field diagnostics based on observations of magnetohydrodynamic (MHD) waves, has been widely used to estimate the field strengths of oscillating structures in the solar corona. However, previously magnetoseismology was mostly applied to occasionally occurring oscillation events, providing an estimate of only the average field strength of an oscillating...

Session 3 - Fundamental Plasma Processes in the Solar Atmosphere: Magnetic Reconnection, Waves, Emission, Particle Acceleration

Poster

Waves and oscillations have been shown as a prime means of transporting energy through the solar atmosphere, thus, contributing to the high temperature of the upper layers. In particular, magnetohydrodynamic (MHD) waves are observed in a number of structures in the solar chromosphere, often with observations in the near-ultraviolet (UV) to infrared wavelength range. In this poster, we present...

120. Polarity relevance in flux rope deflections triggered by coronal holes

Session 4 - From Radio to Gamma Rays: Near-Sun Manifestations and Triggering of Solar Flares and Coronal Mass Ejections

Poster

Usually coronal holes (CHs) deviate coronal mass ejections (CMEs) away from them. However, there are some peculiar events reported where the eruption travels towards the CH. To contribute to a space weather forecast efforts, in relation to the prediction of CME trajectories, we study the interaction between flux ropes (FRs) and CHs through numerical simulations. We perform 2.5D numerical...

214. Flares Associated with Slowly Positively Drifting Bursts Observed in 800-2000 MHz

Session 4 - From Radio to Gamma Rays: Near-Sun Manifestations and Triggering of Solar Flares and Coronal Mass Ejections

Poster

The slowly positively drifting bursts (SPDBs) can occur as a single burst or as a group and its frequency drift is usually less than 300 MHz s^-1. The origin of these burst is unknown and they are observed quite rarely. In our Ondrejov radiospectrograph archive we found up to 10 events during the period 2012-2015 and they are connected with flares. We picked 3 flares for the study. As the...
