Clark and Park1 reported regions of enhanced variable emission at millimetre wavelengths on the solar disk. In this communication I compare mechanisms, and...
Solar Fe abundance and magnetic fields. Towards a consistent reference metallicity
Aims: We investigate the impact on Fe abundance determination of including magnetic flux in series of 3D radiation-magnetohydrodynamics (MHD) simulations of...
Solar FLAG hare and hounds: on the extraction of rotational p-mode splittings from seismic, Sun-as-a-star data
We report on results from the first solar Fitting at Low-Angular degree Group (solar FLAG) hare-and-hounds exercise. The group is concerned with the development...
Solar granulation from photosphere to low chromosphere observed in Ba II 4554 Å line
Aims: The purpose of this paper is to characterize the statistical properties of solar granulation in the photosphere and low chromosphere up to 650 km. Methods...
Solar Hα excess during Solar Cycle 24 from full-disk filtergrams of the Chromospheric Telescope
Context. The chromospheric Hα spectral line is a strong line in the spectrum of the Sun and other stars. In the stellar regime, this spectral line is already...
Solar irradiance, cosmic rays and cloudiness over daily timescales
Although over centennial and greater timescales solar variability may be one of the most influential climate forcing agents, the extent to which solar activity...
Solar magnetism eXplorer (SolmeX). Exploring the magnetic field in the upper atmosphere of our closest star
The magnetic field plays a pivotal role in many fields of Astrophysics. This is especially true for the physics of the solar atmosphere. Measuring the magnetic...
Solar multiobject multiframe blind deconvolution with a spatially variant convolution neural emulator
Context. The study of astronomical phenomena through ground-based observations is always challenged by the distorting effects of Earth's atmosphere. Traditional...
