  1. 6. Secular oscillations and Kozai cycles in planetary systems

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

    Author : Joel Wallenius; [2014]
    Keywords : Kozai effect; Kozai mechanism; secular oscillations; hot Jupiters; planets; planetary systems; Physics and Astronomy;

    Abstract : The origin of the class of exoplanets typically referred to as hot Jupiters is to this day an unsettled matter. Some of the proposed formation channels predict certain values of the spin-orbit misalignment parameter, i.e. the angle between the stellar rotation axis, and the angular momentum vector of the planet orbit.

  3. 7. Noise sources in the electric field antenna on the ESA JUICE satellite

    University essay from

    Author : Elias Odelstad; [2013]
    Keywords : JUICE; noise; quasi-thermal noise; QTN; Nyquist noise; shot noise; Langmuir probes; electric field probes;

    Abstract : The noise in the Langmuir Probe and Plasma Wave Instrument (LP-PWI) on board ESA:s future Jupiter satellite JUICE (Jupiter ICy Moons Explorer) was investigated. Thermal Johnson-Nyquist noise and shot noise, caused by fluctuations in the probe-plasma currents, were combined with the quasi-thermal noise (QTN) due to thermal fluctuations in the electric field in the plasma, using a small signal equivalent circuit model.
