The H $I^\pm$ line as a probe of chromospheric magnetic fields

Harsh Mathur, Jayant Joshi, Thore Espedal Moe +2

We explore the diagnostic potential of the H $I^\pm$ line for probing the chromospheric magnetic field using a realistic 3D radiative magnetohydrodynamic (rMHD) model. The Stokes profi…

Clustering analysis of Ca {\sc i} 4227 line polarization using magnetohydrodynamic simulations of the solar atmosphere

Harsh Mathur, L. S. Anusha, Devang Agnihotri

Ca {\sc i} 4227 Ã \, line is a strong resonance line formed in the Solar chromosphere. At the limb, it produces the largest scattering polarization signal. So far, modeling the lin…

Simultaneous spectropolarimetric observations in the H $I^\pm$ and Ca II 8662 Ã lines of an active region

Harsh Mathur, K. Nagaraju, Rahul Yadav +1

We present spectropolarimetric observations of an active region recorded simultaneously in the H $I^\pm$ Ca II 8662 Ã lines. The sunspot exhibits multiple structures, including a light…
