The Formation of a Multifilament System Driven by Photospheric Converging Motions in a Bipolar Sunspot

The Astrophysical Journal Letters
Solar filaments are believed to be a clump of cold plasma accumulated in the magnetic dips. However, the magnetic configuration of filaments and the key factors for their formation remains elusive.

Case Studies on Pre-eruptive X-class Flares using R-value in the Lower Solar Atmosphere

The Astrophysical Journal
The R -value is a measure of the strength of photospheric magnetic polarity inversion lines in active regions (ARs). This work investigates the possibility of a relation between R -value variations and the occurrence of X-class flares in ARs, not in the ...

Radiation Spectrum of the Photospheric Emission for a Turbulent Relativistic Jet

The Astrophysical Journal
The prompt gamma rays of gamma-ray bursts (GRBs) may originate from the photosphere of a relativistic jet. However, only a few GRBs have been observed with evident blackbody-like emission, for example, GRB 090902B.
