Multiwavelength Emission of Gamma-Ray Burst Prompt Phase. II. Spectral Polarimetry
The Astrophysical JournalPolarization spectra were predicted within the photosphere model. To seek more clues to distinguish between the models, both the time-resolved and time-integrated polarization spectra from optical band to MeV gamma-rays of the magnetic reconnection model

On Photospheric Flows and Chromospheric Corks
, 1994 Proper motions of granules are measured by local correlation tracking on a 4.5 h image sequence obtained with the Swedish Vacuum Tower Telescope at La Palma. A 2 arcsec spatial low-pass filter is applied to obtain meso-scale flow patterns. We find that their characteristic lifetime (1/e value) has a lower limit of five to six hours.

The Astrophysical JournalThe time-integrated polarization degree (PD) in the prompt optical band of a gamma-ray burst (GRB) was predicted to be less than 20%, while the time-resolved one can reach as high as 75% in the photosphere model.

Deconstructing Photospheric Spectral Lines in Solar and Stellar Flares
The Astrophysical JournalDuring solar flares, spectral lines formed in the photosphere have been shown to exhibit changes to their profiles despite the challenges of energy transfer to these depths.
