  1. 1. Forming wide-orbit planets via pebble accretion

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nerea Gurrutxaga; [2023]
    Keywords : Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

    Abstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE

  3. 2. Spectroscopic model characterisation of hot exoplanet atmospheres

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Elin Sandvik; [2022]
    Keywords : Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Abstract : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. READ MORE

  4. 3. Exploring the Diversity of Exoplanets

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rebecka Svensson; [2021]
    Keywords : Exoplanets; Super-Earth; Sub-Neptune;

    Abstract : The search for extrasolar planets had been ongoing for many years when Mayorand Queloz discovered 51 Pegasi b in 1995. It was a giant gas planet similar to Jupiter, but with a larger radius and of only half of Jupiter’s mass. Theso called Hot Jupiter was observed to orbit its host star 7 times closer thanMercury is orbiting the Sun. READ MORE

  5. 4. Detecting Earth-like exoplanets using high-dispersion nulling interferometry

    University essay from KTH/Tillämpad fysik

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

    Abstract : 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.

  6. 5. The Milky Way and its Exoplanets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jesper Nielsen; [2021]
    Keywords : Planets and Satellites; Exoplanets; Occurrence Rates; Physics and Astronomy;

    Abstract : The detections of over 4000 exoplanets as of today has shown that they exist in a wide range of different configurations, otherwise known as architectures. Recently, studies have been made trying to link the environment of host stars to the architectures of their planetary systems and have found that the architectures of planetary systems may not necessarily be uniform in the Milky Way.
