1. Classical Limits in Planetary Motion and Gravitational Radiation
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
2. Origin of blue straggler stars in the Milky Way halo
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
3. Have Radial Velocity Surveys Missed Any Planets?
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
4. Capture into mean motion resonance
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : 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. LÄS MER
5. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : 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. LÄS MER
