Apparent Transverse Motion of Light Bridges Coupled to Coronal Loop Dynamics

Atul Bhat, Sreejith Padinhatteeri, J. M. Borrero +1

Light bridges are commonly observed in active regions and are interpreted as signatures of magnetoconvective processes in sunspots. Several studies have attempted to classify them…

Chromospheric and photospheric properties of sunspots as inferred from Stokes inversions under magneto-hydrostatic and non-local-thermodynamic equilibrium

A. Vicente Arevalo, J. M. Borrero, I. Milic +3

Sunspots are crucial for exploring how magnetic fields and plasma flows interact in the solar atmosphere, spanning from the stable photosphere to the shock-dominated chromosphere.…

The role of the Lorentz force in sunspot equilibrium

J. M. Borrero, A. Pastor Yabar, M. Schmassmann +3

Sunspots survive on the solar surface for time-scales ranging from days to months. This requires them to be in an equilibrium involving magnetic fields and hydrodynamic forces. Unf…

Solar internetwork magnetic fields: Statistical comparison between observations and MHD simulations

Elias Ebert, Ivan Milic, Juan Manuel Borrero

Although the magnetic fields in the quiet Sun account for the majority of the magnetic energy in the solar photosphere, inferring their exact spatial distribution, origin, and evol…

The structure of sunspot penumbrae IV. MHS equilibrium for penumbral flux tubes and the origin of dark core penumbral filaments and penumbral grains

J. M. Borrero

We study the magnetohydrostatic equilibrium of magnetic flux tubes with circular cross sections embedded in a magnetic surrounding atmosphere. We solve the static momentum equation…
