Depolarization of MgH Solar Lines by Collisions with Hydrogen Atoms
Saleh Qutub, Yulia Kalugina, Moncef Derouich
Interpretations of the very rich second solar spectrum of the MgH molecule face serious problems owing to the complete lack of any information about rates of collisions between the…

Effect of the isotropic collisions with neutral hydrogen on the polarization of the CN solar molecule
S. Qutub, M. Derouich, Y. N. Kalugina +2
Our work is concerned with the case of the solar molecule CN which presents conspicuous profiles of scattering polarization. We start by calculating accurate PES for the singlet an…

Transient reducing greenhouse warming on early Mars
Robin Wordsworth, Yulia Kalugina, Sergei Lokshtanov +5
The evidence for abundant liquid water on early Mars despite the faint young Sun is a long-standing problem in planetary research. Here we present new ab initio spectroscopic and l…
