1. 1. Mean Motion Resonances and Planetary Scattering

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

   Author : Erik Dahlöf; [2018]
   Keywords : mean motion resonance; orbit resonance; planetary dynamics; planet-planet scattering; planetary scattering; eccentricity; inclination; planet systems; disturbing force; orbit dynamics; orbital elements; planets; exoplanets; scattering phase; relaxation; dynamical instabilities; N-body; protoplanetary disk; planet migration; eccentricity damping; inclination damping; planet-disk interactions; Physics and Astronomy;

   Abstract : 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. READ MORE

3. 2. Grain size distribution in protoplanetary disks

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

   Author : Erik Dahlöf; [2016]
   Keywords : grain growth; protoplanetary disk; grain size distribution; coagulation; fragmentation; opacity; disk opacity; accretion disk; disk structure; Physics and Astronomy;

   Abstract : Protoplanetary disks consist of matter in both gas and solid form. The sizes of the solid particles, dust grains, although in minority compared to the gas, are important in the formation of larger bodies such as planetesimals. This is a topic which has been widely explored. READ MORE
