Description:: Neutron star mergers instigate a wealth of observable astrophysical signals, offering key insights into interdisciplinary questions in stellar astronomy, nuclear physics, cosmology, and atomic physics. The coalescence of neutron stars and/or black holes produces gravitational wave emission, only recently accessible to ground-based laser-interferometric detectors. Additionally, these mergers can incite emission...

Description:: Type IIb supernovae (SNe) are important candidates to understand mechanisms that drive the stripping of stripped-envelope (SE) supernova (SN) progenitors. ', 'While binary interactions and their high incidence are generally cited to favor them as Type IIb SN progenitors, this idea has not been tested using models covering a broad...

Description:: In this thesis I develop and apply techniques to the masses and eccentricities of tran-siting exoplanets from their transit timing variations. These techniques include both analytic and numerical means for measuring planet masses and orbits and assessing the robustness of the inferred properties. I apply these techniques to a sample...

Description:: In this thesis we investigate the orbital evolution of planets in binaries.Unlike our own Solar System, at least one out of five planetary systems known to date is associated with additional stellar companions. Despite their large distances from the planetary systems, these stellar companions play an important role in significantly...

Description:: Planets and planetary systems change in brightness as a function of time. These "light curves" can have several features, including transits where a planet blocks some starlight, eclipses where a star obscures a planet's flux, and rotational variations where a planet reflects light differently as it spins. One can measure...
