  1. 6. Detailed analysis of the chemical composition of stars harboring Earth-like planets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Lorena Acuña Aguirre; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. READ MORE

  3. 7. Can planet formation explain the observed differences in the chemical composition of binary stars?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Rebecca Forsberg; [2017]
    Keywords : binary stars; planet formation; protoplanetary disc; Physics and Astronomy;

    Abstract : A suggested explanation for the observed differences in chemical abundances in binary stars has been planet formation (e.g. Tucci Maia et al. 2014). READ MORE

  4. 8. Neutron capture elements in the early Universe

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Abdalrahman Abohalima; [2017]
    Keywords : metal-poor; early Universe; neutron capture; Physics and Astronomy;

    Abstract : Metal-poor (MP) stars in the Milky Way (the Galaxy) and its satellite galaxies open a window into the earliest times in the history of the Universe, probing the chemistry of the earliest times. Recent galaxy formation simulations predict that the oldest MP stars are those on tightly bound orbits in the inner regions of a galaxy (Tumlinson 2010). READ MORE

  5. 9. The chemical composition of hot and cold gas giants

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Linn Eriksson; [2016]
    Keywords : Planet formation; hot Jupiter; pebble accretion; Physics and Astronomy;

    Abstract : Exoplanet surveys have identified a category of giant planets that orbit very close to their host stars - the so-called hot Jupiters. The origin of such hot Jupiters is a long standing puzzle and has been closely investigated since the first discovery of such planets in 1995. READ MORE

  6. 10. Future directions in the study of Asymptotic Giant Branch Stars with the James Webb Space Telescope

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Adam Hjort; [2016]
    Keywords : JWST; AGB; Stellar models; Stars; WISE; Photometry; Asymptotic giant branch; carbon stars;

    Abstract : In this study we present photometric predictions for C-type Asymptotic Giant Branch Stars (AGB) stars from Eriksson et al. (2014) for the James Webb Space Telescope (JWST) and the Wide-field Infrared Survey Explorer (WISE) instruments. READ MORE
