Photospheric magnetic vortex structures [PDF]
Annales Geophysicae, 2011 Using direct numerical magneto-hydrodynamic (MHD) simulations, we demonstrate the evidence of two physically different types of vortex motions in the solar photosphere.

The photosphere of Pleione [PDF]
Symposium - International Astronomical Union, 1994 In this paper we report results concerning the photospheric Balmer discontinuity of Pleione. They show that after the Be → Be-shell phase transitions, the stellar photosphere keeps its characteristics unchanged.

Vorticity in the solar photosphere [PDF]
, 2010 Aims. We use magnetic and non-magnetic 3D numerical simulations of solar granulation and G-band radiative diagnostics from the resulting models to analyse the generation of small-scale vortex motions in the solar photosphere.Methods.

Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension [PDF]
, 2009 Aims: We analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentrations, mimicking sunspots with various representative magnetic field configurations ...

Signatures of Magnetic Flux Ropes in the Low Solar Atmosphere Observed in High Resolution
Frontiers in Astronomy and Space Sciences, 2019 Magnetic flux ropes (MFRs) are important physical features closely related to solar eruptive activities with potential space weather consequences. Studying MFRs in the low solar atmosphere can shed light on their origin and subsequent magnetic structural

Simulations of magneto-convection in the solar photosphere [PDF]
, 2004 We have developed a 3D magnetohydrodynamics simulation code for applications in the solar convection zone and photosphere. The code includes a non-local and non-grey radiative transfer module and takes into account the effects of partial ionization.

Recent Results for Widths of Lines Important in the Spectra of Cool Stars
Open Astronomy, 2011 The broadening of spectral lines by neutral perturbers is an important factor in the interpretation of the observed spectra of cool stars and is often included in the analysis by using a simple van der Waals formula. Detailed calculations are carried out

Photosphere Recession and Luminosity of Homologous Explosions Revisited
, 2022 By assuming the photosphere located at the outmost edge of the ejecta, Arnett et al. (1980, 1982, 1989) presented the light curves of homologous explosions in supernovae analytically and numerically to include recombination effects.
