  1. Development of a Self-Consistent Gas Accretion Model for Simulating Gas Giant Formation in Protoplanetary Disks

    Russell, John L.University of Guelph2011

    … planets belonging to a new class of `distant gas giants' have also been discovered with orbits of 30 to 100 times that of Jupiter. The wide variety of different planet formation outcomes stem from a complex interplay between gravitational interactions, hydrodynamic interactions and competitive …

  2. Statistical analyses of exoplanetary systems and individual studies of the atmospheres of two sub-Neptune-sized planets

    Guo, Xueying,Ph. D.Massachusetts Institute of Technology.Massachusetts Institute of Technology2020

    … hypothesis that the discrepancy between close-in gas giant occurrence rates measured from transit surveys and from the California radial velocity survey can be completely explained by their stellar metallicity difference, using the relation between occurrence rates and stellar properties.

  3. Turbulence in geophysics: from rotating, ionized fluids to sediment transport

    Benavides, Santiago JoséMassachusetts Institute of Technology2022

    … I: "Turbulence in the semiconducting regions of gas giant planets." The 'semiconducting' regions of gas giant planets, which lie between the fully ionized and electrically-neutral regions, have three distinct properties that make the dynamical nature of their flows unique. They are (i) …

  4. The stability of short-period extrasolar giant planets

    Koskinen, T.T.UCL (University College London)2008

    … thermosphere-ionosphere model for extrasolar giant planets (EXOTIM) has been developed. This is the first such model reported in the literature. This thesis contains an extensive description of the model and the methods adopted in modelling the different physical processes expected in the …

    Blanco, Joan Marie 1984-University of Houston2017

    … Gulf of Venezuela (GOV), a 17 TCF of thermogenic gas giant - hosted in a 300-m-thick, carbonate (red algae) reservoir - stimulated reevaluation of potential hydrocarbon reservoirs in Cenozoic carbonate rocks in northwestern South America. I use regional gravity and magnetic data integrated with a …

  6. The albedo of an exoplanet: spacebased photometry of the transiting system HD 209458

    Rowe, JasonUniversity of British Columbia2008

    … ever obtained. The limit on the albedo of the gas giant HD 209458b means it much less reflective as Jupiter. This result rules out the presence of reflective clouds in the atmosphere of HD 209458b and has already enabled theoretical modeling of far-infrared measurements to contrain the planet's …
