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

   Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Lydia Schollmeier; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : 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. LÄS MER

3. 2. Identifying Transit Timing Variations in K2 and TESS light curves

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Linn Friis-Liby; [2022]
   Nyckelord :Exoplanets; TESS; K2; Transit Timing Variations;

   Sammanfattning : Aims. The aim of this work is to investigate any presence of transit timing variations (TTVs) in a sample of observed targets that has light curves in both K2 mission data and TESS mission data.  Methods. The original sample utilised here was one from the doctoral thesis of D. LÄS MER

4. 3. Multi-planetary Systems from Simulated TESS Transit Timing Variations

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Lucas Hellström; [2018]
   Nyckelord :Transit timing variations; TTV; TESS; Physics and Astronomy;

   Sammanfattning : A transit is a phenomenon where a planet passes between its host star and an observer blocking out part of the light from the star. This decrease can be measured and used to gain information about the planet. The Kepler and TESS telescopes are examples of space telescopes using the transit method to detect exoplanets. LÄS MER
