The solar Mg abundance from strong spectral lines in the infrared

Autor: Al Moulla, Khaled

This project aims to determine the solar Mg abundance with two infrared spectral lines: MgI λ10811 and λ10965. Downloaded line data from VALD are updated with modern values for the oscillator strengths and van der Waals damping parameters, the latt

Turbulence at MHD and sub-ion scales in the magnetosheath of Saturn : a comparative study between quasi-perpendicular and quasi-parallel bow shocks using in-situ Cassini data

Autor: Al Moulla, Khaled

The purpose of this project is to investigate the spectral properties of turbulence in the magnetosheath of Saturn, using in-situ magnetic field measurements from the Cassini spacecraft. According to models of incompressible, turbulent fluids, the en

Dependence of Solar Activity Signals on the Formation Temperature of Spectral Lines

Autor: Al Moulla, Khaled, Dumusque, Xavier, Zhao, Yinan, Cretignier, Michaël, Valenti, Jeff A.

It is evident from the existing literature that the interplay between magnetic fields and multi-scale convection currently prevents radial velocity (RV) precision from reaching the sub-m/s level required to detect Earth-twins around Sun-like stars. I
