    Abstract : The East African Community (EAC) is an intergovernmental organisation comprised of six countries, five of which are classed as having a low development level and one of which is classed as medium. The region has low rates of human development and electrical connectivity but is committed to meeting the universal access and clean energy goals of Sustainable Development Goal 7. READ MORE

  5. 4. The solar Mg abundance from strong spectral lines in the infrared

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Khaled Al Moulla; [2019]
    Keywords : Sun: Mg abundance – line broadening: ABO theory – VALD – SME;

    Abstract : 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 latter obtained through ABO theory. READ MORE

  6. 5. Identification of elements and molecules in the spectra of an M dwarf star using high resolution infrared spectroscopy.

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Markus Pudas; [2017]
    Keywords : M dwarf stars; line list ; spectroscopy ; high resolution infrared; telluric spectra;

    Abstract : M dwarfs are abundant and long-lived stellar objects. The formation of planets around stars in stellar systems is believed to be metallicity dependent. To determine the metallicity with synthetic spectrum analysis, the elements producing the absorption lines ofthe spectra first have to be identified. READ MORE
