1. 1. Forming wide-orbit planets via pebble accretion

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

   Author : Nerea Gurrutxaga; [2023]
   Keywords : Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

   Abstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE

3. 2. The Effect of Gravitational Encounters on Binary Planetesimals

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : John Gillan; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Binary planetesimals in the Kuiper belt can experience close encounters with other bodies. These encounters can disturb the orbital dynamics of the binary in several ways. Energy can be added to the system by the impactor body and lead to the disruption of the binary. READ MORE

4. 3. Capture into mean motion resonance

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Kaltrina Kajtazi; [2021]
   Keywords : MMR; Mean motion resonance; Planetary dynamics; First order MMR; Numerical integration with N-body; Physics and Astronomy;

   Abstract : Orbital or mean motion resonance (MMR) occurs when the orbital period ratio between two planets is close to a ratio of small integers. MMR can protect planets from collisions and affects the overall final architecture of the system. READ MORE

5. 4. Polarisation-resolved super-resolution microscopy

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Wouter Duverger; [2021]
   Keywords : biophysics; microscopy; super-resolution microscopy; polarisation microscopy; STED; Physics and Astronomy;

   Abstract : This project aims to implement polarisation microscopy on the Tegenfeldt STED (stimulated emission depletion) microscope. STED microscopy is a targeted optical super-resolution method that can attain sub-diffraction resolution using visible light. READ MORE

6. 5. How did Jupiter form?

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Calle Ahlgren; [2019]
   Keywords : Planet formation; Planet migration; Physics and Astronomy;

   Abstract : Two relatively new concepts in planetary science are planetary migration; wherein the planets migrate through the protoplanetary disk as they form, and pebble accretion; wherein the planetesimals which become terrestrial planets and giant planet cores grow through the accretion of small pebbles. Planetary migration has become a generally accepted concept but there is still much to be learned even about how it affected the formation of our own solar system. READ MORE
