1. 1. How Stellar Tides Affect Planet Evolution

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Madison Green; [2019]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Planets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. LÄS MER

   Sammanfattning : The observed distribution of giant exoplanet eccentricities and inclinations are significantly larger than what is measured for their Solar system analogues, Jupiter and Saturn. Since the first observations of exoplanets, planet-planet scattering has been proposed as a possible mechanism for exciting the eccentricities and inclinations of giant exoplanets. LÄS MER
