1. 1. Detecting Transiting Exoplanets in Crowded Fields

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Eddie Larsson; [2022]
   Nyckelord :Transit method; Globular cluster; crowded environments; exoplanets; transiting exoplanets; Physics and Astronomy;

   Sammanfattning : The first planet orbiting a main-sequence star was discovered in 1995. Since then more than 4000 additional exoplanets have been discovered. This is a rapidly evolving field in astrophysics. One of the most common ways to detect an exoplanet is through transit, as the brightness of the host star decreases. LÄS MER

3. 2. Detecting Earth-like exoplanets using high-dispersion nulling interferometry

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Germain Garreau; [2021]
   Nyckelord :Applied Physics; Instrumental Optics; Exoplanets Detection; Interferometry; Spectroscopy; Tillämpad fysik; Instrumentoptik; Exoplaneter upptäckt; Interferometri; Spektroskopi;

   Sammanfattning : The detection of Earth-like exoplanets and the characterization of their atmospheres is a challenge one needs to solve to assess their habitability and the presence of life in the universe. If this challenge is still unresolved today, even in the era of giant telescopes, it is mainly because of the very high contrast between these exoplanets and their host star and also their proximity.

4. 3. The Giants and their role in Ragnarök

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Fran Bartolic; [2015]
   Nyckelord :exoplanets stellar evolution tides planet engulfment; Physics and Astronomy;

   Sammanfattning : Observed population of giant planets around evolved stars shows a paucity of planets with semi-major axes below 0.5 au, in contrast to main sequence stars where those planets are present. LÄS MER
