1. 1. Classical Limits in Planetary Motion and Gravitational Radiation

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Sebastian Gustasson; Emma Andersson; [2023]
   Keywords : general relativity; frame-dragging; gravitational radiation;

   Abstract : In this report, we analyze general relativistic effects on celestial bodies, including gravitational strength in different metrics, gravitational radiation, and frame-dragging. We present simulation methods for classical and general relativistic motion, through the use of systems of equations that may be numerically integrated. READ MORE

3. 2. Origin of blue straggler stars in the Milky Way halo

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

   Author : Adam Brcek; [2023]
   Keywords : Blue Straggler; Galactic Halo; Spectroscopic Surveys; Binary Star Evolution; Mass Transfer; Physics and Astronomy;

   Abstract : Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. READ MORE

4. 3. 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

5. 4. 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

6. 5. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Akila Wajirakumara; [2021]
   Keywords : ;

   Abstract : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.
