Diffusion in the chromosphere and the composition of the solar corona and energetic particles [PDF]

Composition observations, in the solar photosphere, and in the upper transition region (TR) and corona imply a change of composition of the solar atmosphere somewhere between the photosphere and the upper TR.

Multiwavelength Emission of Gamma-Ray Burst Prompt Phase. II. Spectral Polarimetry

The Astrophysical Journal
Polarization 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

Magnetic Coupling in the Quiet Solar Atmosphere

, 2009
Three kinds of magnetic couplings in the quiet solar atmosphere are highlighted and discussed, all fundamentally connected to the Lorentz force. First the coupling of the convecting and overshooting fluid in the surface layers of the Sun with the ...

Multiwavelength Emission of the Gamma-Ray Burst Prompt Phase. I. Time-resolved and Time-integrated Polarizations

The Astrophysical Journal
The 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.

Addemdum to: ''The Mathematical Structure of Quantum Superspace as a Consequence of Time Asymmetry''

, 2000
In this paper we improve the results of sec. VI of paper [M. Castagnino, Phys. Rev. D 57, 750 (1998)] by considering that the main source of entropy production are the photospheres of the ...

Deconstructing Photospheric Spectral Lines in Solar and Stellar Flares

The Astrophysical Journal
During 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.

The Quiet-Sun Photosphere and Chromosphere

, 2011
The overall structure and the fine structure of the solar photosphere outside active regions are largely understood, except possibly important roles of a turbulent near-surface dynamo at its bottom, internal gravity waves at its top, and small-scale ...
