  2. 1. Atmospheric Species and Spectral Radiation in Terrestrial Exoplanets : Implications for Astrobiology

    Author : Samuel Konatham; Javier Martin-Torres; María-Paz Zorzano Mier; Akos Kereszturi; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exoplanets; Atmospheres; Habitability; Human vision; Scotopic vision; Photopic vision; Spectral radaition; Atmosfärsvetenskap; Atmospheric science;

    Abstract : The physical properties of the planets and their parent stars are fundamental in the composition of atmospheres and radiative environments, which fundamentally determine their surface temperature and habitability. The atmospheric composition and radiation play a vital role in the emergence of life. READ MORE

  4. 2. Debris disks from an astronomical and an astrobiological viewpoint

    Author : Gianni Cataldi; Alexis Brandeker; Göran Olofsson; Eric Stempels; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; debris disks; planetary systems; exoplanets; astrobiology; circumstellar matter; biomarker; biosignature; extraterrestrial life; Astronomy; astronomi;

    Abstract : In this licentiate thesis, I consider debris disks from an observational, astronomical viewpoint, but also discuss a potential astrobiological application. Debris disks are essentially disks of dust and rocks around main-sequence stars, analogue to the Kuiper- or the asteroid belt in our solar system. READ MORE

  5. 3. The Formation of Giant Planets

    Author : Michiel Lambrechts; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Planet formation; Solar System; Exoplanets; Giant planets; Hydrodynamics;

    Abstract : Giant planets form embedded in a protoplanetary disc around a young star. Close to the midplane a large fraction of the available mass in solids is found in particles of cm to dm in size, which drift towards the star due to friction with the surrounding gas. READ MORE

  6. 4. High Resolution Transmission Spectroscopy of Exoplanets

    Author : Ansgar Wehrhahn; Nikolai Piskunov; Ulrike Heiter; Jason Wright; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; astronomy; spectroscopy; Astronomy; Astronomi;

    Abstract : A large number of exoplanets has been observed in the last three decades, but still for most of them we know comparatively little about the atmospheres of these distant planets. This is of particular interest as there exist types of planets that don't have an analogy in our own solar system, like hot Jupiters or super Earths. READ MORE

  7. 5. Stellar surface structures and the astrometric search for exoplanets

    Author : Urban Eriksson; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Not available.... READ MORE
