Spatial resolution effects on the solar open flux estimates

Ivan Milic, Rebecca Centeno, Xudong Sun +2

Spectropolarimetric observations used to infer the solar magnetic fields are obtained with a limited spatial resolution. The effects of this limited resolution on the inference of…

A Possible Mechanism for "Late Phase" in Stellar White-Light Flares

Kai E. Yang, Xudong Sun, Graham S. Kerr +1

M-dwarf flares observed by the \textit{Transiting Exoplanet Survey Satellite} (\textit{TESS}) sometimes exhibit a "peak-bump" light-curve morphology, characterized by a secondary,…

Large Photospheric Doppler Shift in Solar Active Region 12673: I. Field-Aligned Flows

Jiayi Liu, Xudong Sun, Peter W. Schuck +3

Delta () sunspots sometimes host fast photospheric flows along the central magnetic polarity inversion line (PIL). Here we study the strong Doppler shift signature in the centra…

The S-Web Origin of Composition Enhancement in the Slow-to-Moderate Speed Solar Wind

B. J. Lynch, N. M. Viall, A. K. Higginson +3

Connecting the solar wind observed throughout the heliosphere to its origins in the solar corona is one of the central aims of heliophysics. The variability in the magnetic field,…

On the nature of photospheric horizontal magnetic field increase in major solar flares

Lijuan Liu, Zhenjun Zhou, Yuming Wang +2

Rapid increase of horizontal magnetic field () around the flaring polarity inversion line is the most prominent photospheric field change during flares. It is considered to be…

Imaging Observations of Magnetic Reconnection in a Solar Eruptive Flare

Y. Li, X. Sun, M. D. Ding +2

Solar flares are one of the most energetic events in the solar atmosphere. It is widely accepted that flares are powered by magnetic reconnection in the corona. An eruptive flare i…
