Waves in the solar photosphere [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 The solar photosphere is a partially ionized medium with collisions between electrons, various metallic ions and neutral hydrogen playing an important role in the momentum and energy transport in the medium.

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.

Vorticity in the solar photosphere [PDF]
Astronomy & Astrophysics, 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.

Structure of the solar photosphere studied from the radiation hydrodynamics code ANTARES. [PDF]
Astrophys Space Sci, 2017 The ANTARES radiation hydrodynamics code is capable of simulating the solar granulation in detail unequaled by direct observation. We introduce a state-of-the-art numerical tool to the solar physics community and demonstrate its applicability to model ...

Solar photosphere magnetization [PDF]
Astronomy & Astrophysics, 2020 International audienceContext. A recent review shows that observations performed with different telescopes, spectral lines, and interpretation methods all agree about a vertical magnetic field gradient in solar active regions on the order of 3 G km −1 ...

Global isothermal oscillations in the solar photosphere
Kinematics and Physics of Celestial Bodies, 2011 По данным наблюдений на космических аппаратах VIRGO (SOHO) и ДИФОС-Ф (КОРОНАС-Ф) осцилляций яркости Солнца получены стратификации возмущений концентрации водорода, порождающие изотермические колебания фотосферных слоев Солнца.

On the Origin of the Photospheric Magnetic Field
The Astrophysical Journal, 2022 This article presents results that challenge the paradigms that (1) the convection zone is the source of the radial magnetic field in the photosphere and (2) that coronal currents are neutralized from the perspective of the photosphere.

Journal of Space Weather and Space Climate, 2022 Studies of the Sun and the Earth’s atmosphere and climate consider solar variability as an important driver, and its constant monitoring is essential for climate models. Solar total and spectral irradiance are among the main relevant parameters. Physical
