Modelling solar radial velocities and photometric variability with SOAPv4
Alba Barka, Eduardo Cristo, Ãngela R. G. Santos +5
Stellar activity remains one of the main limitations in the detection of Earth-like planets using radial velocity (RV) measurements. The Sun, as the only star for which surface fea…
A New Multi-Constraint Potential Field Source Surface (PFSS) Extrapolation Model
C. Antonio, I. Chifu, R. Gafeira +1
The Potential Field Source Surface (PFSS) model is the most used approach for extrapolating the global coronal magnetic field, offering efficiency and strong performance at large s…
Magnetic braking and dynamo evolution of Hydri
A. R. G. Santos, T. S. Metcalfe, O. Kochukhov +3
The evolution of magnetic braking and dynamo processes in subgiant stars is essential for understanding how these stars lose angular momentum. We investigate the magnetic braking a…
The Sun at millimeter wavelengths V. Magnetohydrodynamic waves in a fibrillar structure
Maryam Saberi, Shahin Jafarzadeh, Sven Wedemeyer +4
Magnetohydrodynamic (MHD) waves, playing a crucial role in transporting energy through the solar atmosphere, manifest in various chromospheric structures. Here, we investigated MHD…
Sausage, kink, and fluting MHD wave modes identified in solar magnetic pores by Solar Orbiter/PHI
S. Jafarzadeh, L. A. C. Schiavo, V. Fedun +25
Solar pores are intense concentrations of magnetic flux that emerge through the Sun's photosphere. When compared to sunspots, they are much smaller in diameter and hence can be imp…
