Magnetic Coupling Between A “Hot Jupiter” Extrasolar Planet And Its Pre-Main-Sequence Central Star, Brooke E. Alarcon
Magnetic Coupling Between A “Hot Jupiter” Extrasolar Planet And Its Pre-Main-Sequence Central Star, Brooke E. Alarcon
Master's Theses - Daytona Beach
In order to understand the short-period pile-up of extrasolar planets, the magnetic torque of a pre-main-sequence central star on a single orbiting "hot Jupiter" planet is calculated. The star's magnetic field is modeled as a dipole magnetic field. The time-dependant stellar radius is calculated for four different stellar mass sizes; 2Msum \.5Msum \Msum and 0.5Msurt. The minimum planetary ionization for the giant gas planet to be nearly frozen to the magnetic field lines is calculated. The changing angular momentum of an orbiting body was balanced with the magnetic torque of the central star to provide …
Dynamics Of Nonlinear Diffusion Processes, Dustin A. Sipka
Dynamics Of Nonlinear Diffusion Processes, Dustin A. Sipka
Master's Theses - Daytona Beach
The purpose of this thesis is to analyze nonlinear diffusion processes. In particular, some of the results arrived at by Newman and Sagan in their 1981 paper "Galactic Civilizations: Population Dynamics and Interstellar Diffusion," will be reproduced by different means. First, a thorough analysis of the linear diffusion equation will be performed in order to test a numerical algorithm that can solve the nonlinear diffusion equation and look at the processes of interest with sufficient accuracy. Once the algorithm is tested and shows good resolution it is used to solve the nonlinear equation. The post processing is then done to …
