On the Impulsive Heating of Quiet Solar Corona
Vishal Upendran; Durgesh Tripathi
<jats:title>Abstract</jats:title> <jats:p>The solar corona consists of a million degree Kelvin plasma. A complete understanding of this phenomenon demands the study of quiet Sun (QS) regions. In this work, we study QS regions in the 171 Å, 193 Å, and 211 Å passbands of the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory, by combining the empirical impulsive heating forward model of Pauluhn & Solanki with a machine-learning inversion model that allows uncertainty quantification. We find that there are ≈2–3 impulsive events per minute, with a lifetime of about 10–20 minutes. Moreover, for all the three passbands, the distribution of power-law slope <jats:italic>α</jats:italic> peaks above 2. Our exploration of correlations among the frequency of impulsive events and their timescales and peak energy suggests that conduction losses dominate over radiative cooling losses. All these findings suggest that impulsive heating is a viable heating mechanism in QS corona.</jats:p>

Dynamical Surface Imaging of λ Andromedae

<jats:title>Abstract</jats:title> <jats:p>We present temperature maps of RS CVn star <jats:italic>λ</jats:italic> Andromedae, reconstructed from interferometric data acquired in 2010 and 2011 by the Michigan Infra-Red Combiner instrument at the Center for High Angular Resolution Astronomy Array. To constrain the stellar parameters required for this imaging task, we first modeled the star using our GPU-accelerated code SImulation and Modeling Tool for Optical Interferometry. The stellar surface was then imaged using our open source interferometric imaging code ROTational Image Reconstruction, in the process further refining the estimation of stellar parameters. We report that the measured angular diameter is 2.742 ± 0.010 mas with a limb-darkening coefficient of 0.231 ± 0.024. While our images are consistent with those of prior works, we provide updated physical parameters for <jats:italic>λ</jats:italic> Andromedae (<jats:italic>R</jats:italic> <jats:sub>⋆</jats:sub> = 7.78 ± 0.05 <jats:italic>R</jats:italic> <jats:sub>⊙</jats:sub>, <jats:italic>M</jats:italic> <jats:sub>⋆</jats:sub> = 1.24 ± 0.72 <jats:italic>M</jats:italic> <jats:sub>⊙</jats:sub>, and log <jats:italic>L/L</jats:italic> <jats:sub>⊙</jats:sub> = 1.46 ± 0.04).</jats:p>
