Depolarization and Polarization-Transfer Rates for Solar He I Lines due to Collisions with Neutral Hydrogen
Moncef Derouich, Saleh Qutub
Context. Neutral helium (He I) produces several spectral lines that are widely used for solar diagnostics. The role of collisions between He I atoms and neutral hydrogen (H I) in t…

Depolarization and polarization transfer rates for the C + H collisions in the solar photosphere
S. Qutub, Y. N. Kalugina, M. Derouich
This paper is a continuation of a series of studies investigating collisional depolarization of solar molecular lines like those of MgH, CN and C. It is focused on the case of…

On the collisional sensitivity of polarized Mg II solar lines
M. Derouich, S. Qutub
Neutral and singly ionized states of the Magnesium (Mg) are the origin of several spectral lines that are useful for solar diagnostic purposes. An important element in modeling suc…
