1. 1. Combining E-ELT HIRES instrument and SKA to probe the chemical enrichment by the first stars

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Författare :Aikaterini Stergiopoulou; [2016]
   Nyckelord :Signatures of Population III stars; E-ELT HIRES; SKA; chemical enrichment; Pair Instability Supernovae;

   Sammanfattning : In this project we investigate the feasibility of detecting the signatures of Pop III stars in metal poor second generation stars and in gas clouds at high redshifts. First, the nucleosynthetic yields of Pair Instability Supernova and how they are manifested in gas clouds are presented. LÄS MER

3. 2. Spectroscopic characterization of transiting exoplanets : A study of the possibility to detect atmospheres around exoplanets using SIMPLE

   Kandidat-uppsats, Observationell astrofysik

   Författare :Pierre Waldén; Erik Aronson; [2011]
   Nyckelord :exoplanet; atmosphere; spectrum; extra solar planet; spectroscopy; SIMPLE; E-ELT; ESO; spectrometer; telescope; spectral features; noise; signal to noise; S N; planet; star; red dwarf; atmospheric features; Super-Earth; Earth-like;

   Sammanfattning : This report describes simulations of observations with the near-infrared high-resolution spectrometer SIMPLE that is proposed to the ESO telescope E-ELT. We simulate M4 and G2 stars with transiting Earth-like planets and the goal is to distinguish spectral features originating from the atmosphere of the exoplanet. LÄS MER
