  1. 16. Formation of super-Earths via pebble accretion onto planetesimals

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Daniel Mikkola; [2015]
    Keywords : planet; formation; planet formation; exoplanets; pebble; accretion; pebble accretion; Physics and Astronomy;

    Abstract : Data from NASA's Kepler space telescope, which searches for exoplanets via the transit method, produced 1108 new planetary candidates in 2013 with a total of 91% being smaller than Neptune in size. These were mostly super-Earths, terrestial planets between Earth and Neptune in size, with orbits around 10 days. READ MORE

  3. 17. The Giants and their role in Ragnarök

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

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

    Abstract : 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. READ MORE

  4. 18. Spectroscopic analysis of exoplanet atmospheres : Ground-based high-resolution atmospheric characterization of hot Jupiters using near infrared spectroscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Emelie Stoltz Årevik; [2015]
    Keywords : ground-based high-resolution atmospheric atmosphere characterization hot Jupiters near infrared spectroscopy;

    Abstract : This report is exploring the possibility of characterizing hot Jupiter atmospheres using ground-based high-resolution spectroscopy. The ESO CRIRES infrared spectrometer is selected as the observing tool. Simulated observations are computed for known transiting systems. READ MORE

  5. 19. Secular oscillations and Kozai cycles in planetary systems

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

    Author : Joel Wallenius; [2014]
    Keywords : Kozai effect; Kozai mechanism; secular oscillations; hot Jupiters; planets; planetary systems; Physics and Astronomy;

    Abstract : The origin of the class of exoplanets typically referred to as hot Jupiters is to this day an unsettled matter. Some of the proposed formation channels predict certain values of the spin-orbit misalignment parameter, i.e. the angle between the stellar rotation axis, and the angular momentum vector of the planet orbit.

  6. 20. The Stability of Exomoons in the Habitable Zone

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

    Author : Henrik Nordanger; [2014]
    Keywords : Physics and Astronomy;

    Abstract : This is an analysis of all the planets at exoplanets.org, with the goal of finding out how many of these that could possibly have moons supporting life. READ MORE
