We present Kepler exoplanet occurrence rates for planets between 0.5 and 16 R⊕ and
between 1 and 400 days. To measure occurrence, we use a nonparametric method via a …

Radial-velocity (RV) surveys have discovered hundreds of exoplanetary systems but suffer
from a fundamental degeneracy between planet mass M p and orbital inclination i. In this …

Due to the high dimensionality or multimodality that is common in modern astronomy,
sampling Bayesian posteriors can be challenging. Several publicly available codes based …

This study presents observations of two possible substellar survivors of post-main sequence
engulfment, currently orbiting white dwarf stars. Infrared and optical spectroscopy of GD …

We present the discovery of two mini Neptunes near a 2: 1 orbital resonance configuration
orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest …

This thesis explores extrinsic interaction signatures in cool white dwarfs through
multicomponent optical and infrared spectra coupled with photometry. The first part of the …

Exoplanets orbiting distant stars have revealed to us that no one could have predicted Earth.
Many stars host planets which appear to be made of rock and iron like Earth, but sit at …
