  1. 6. Spectroscopic model characterisation of hot exoplanet atmospheres

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Elin Sandvik; [2022]
    Keywords : Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Abstract : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. READ MORE

  3. 7. Have Radial Velocity Surveys Missed Any Planets?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Shah Raj; [2021]
    Keywords : radial velocity survey; transit method; exoplanet; habitable zone; habitable zone boundaries; HZ; early Mars; recent Venus; stability; instability; chaos; REBOUND; MEGNO; MEGNO maps; Hill sphere; stable systems; unstable systems; Physics and Astronomy;

    Abstract : The project was aimed at numerically assessing exoplanetary systems to distinguish their capabilities of hosting additional planets. The shortcomings of the radial velocity method sometimes causes hindrance in the detection of terrestrial planets. READ MORE

  4. 8. 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. 9. The Milky Way and its Exoplanets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jesper Nielsen; [2021]
    Keywords : Planets and Satellites; Exoplanets; Occurrence Rates; Physics and Astronomy;

    Abstract : The detections of over 4000 exoplanets as of today has shown that they exist in a wide range of different configurations, otherwise known as architectures. Recently, studies have been made trying to link the environment of host stars to the architectures of their planetary systems and have found that the architectures of planetary systems may not necessarily be uniform in the Milky Way.

  6. 10. Evolution and Differentiation of Large Icy Moons

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Piia Tomberg; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Purpose: In preparation of several future missions with the objective to research the large icy moons of the Solar System, it is necessary to have a cohesive understanding of the conditions that might lead to the formation of liquid oceans in these moons. The purpose of this work is to create a numerical model for simulating the temperature evolution of the cores of large icy moons. READ MORE
