Description:
abstract of observational proposal Main Objective: Examine the effect of the waves propagating in the lower solar atmosphere on the abundance variation (First Ionization Potential (FIP) fractionation) Scientific Justification: The various structures in solar atmosphere have different solar abundances, photospheric or coronal. Our goal is to understand how the solar abundances changes in different plasma structures along the solar atmosphere. So far, several theoretical models propose that the waves in the lower solar atmosphere preferentially effect on the ionized particles more than neutral ones depending on their magnetic field configurations and environmental plasma characteristics, which are the main causes for the abundance variations (Laming 2012, 2017). request to SOT SOT observations are optional. If telemetry allows, we request SP maps covering the target region, active region or quiet region (at least FOV needs to be larger than 60 arcsec x 60 arcsec).
