1. 1. Spectroscopy of the Globular Cluster M30

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Författare :Kilian Hikaru Scheutwinkel; [2019]
   Nyckelord :Spectroscopy; Globular Cluster; M30;

   Sammanfattning : Globular Clusters contain very old metal-poor stars in different evolutionary stages evolved from the same primordial cloud. Signatures of atomic in stellar interiors are studied in the metal-poor GC M30. Furthermore, traces of cluster internal pollution depleting alpha elements e.g. LÄS MER

3. 2. Ionospheric model of comet 67P including the effect of solar EUV attenuation

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Författare :Kilian Hikaru Scheutwinkel; [2018]
   Nyckelord :ionosphere; comet 67P CG; Rosetta;

   Sammanfattning : Comets are the most active around their perigees. The increased outgassing can lead to a coma thick enough to effectively absorb the solar EUV radiation, which engenders a self-shielding comet nucleus and inner layers of the ionosphere. LÄS MER

4. 3. Spectral investigation of the globular cluster M30

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Författare :Scheutwinkel Kilian Hikaru; [2018]
   Nyckelord :M30; globular cluster; spectroscopy;

   Sammanfattning : Globular cluster studies suggest that a signature in the spectra of RGB stars in a globular cluster are anti-correlations in Mg-Al and Na-O. In this work, a small sample of 12 RGB stars of the globular cluster M30 is investigated using VLT-UVES high-resolution spectrograph. LÄS MER
