1. 1. N-body simulations of exoplanets and their moons

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

   Author : Lydia Schollmeier; [2024]
   Keywords : Physics and Astronomy;

   Abstract : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. READ MORE

3. 2. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

   University essay from Umeå universitet/Institutionen för fysik

   Author : Gabriella Nordin; [2023]
   Keywords : Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

   Abstract : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. READ MORE

4. 3. Estimating stellar limb darkening using exoplanet transits

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

   Author : Sora Ishida; [2023]
   Keywords : Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

   Abstract : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. READ MORE

5. 4. Simulations of the Tenuous Upper Atmospheres of Exoplanets

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

   Author : Lucian Spitzner; [2023]
   Keywords : astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

   Abstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

6. 5. Search for transiting exoplanets in globular clusters

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

   Author : Oskar Nilsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. READ MORE
