Democratizing & Enhancing Exoplanet Research with the Unistellar Citizen Science Network & Astronomy Modeling Instruction [PDF]
This thesis explores the potential in democratizing and augmenting exoplanet research via citizen science by utilizing a global network of portable image-intensified computerized telescopes, and inquiry-based astronomy instruction. A central objective is

A Pair of Dynamically Interacting Sub-Neptunes around TOI-6054
The Astronomical JournalWe confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type subgiant star TOI-6054 ( V = 8.02, K = 6.673) as a part of the OrCAS radial velocity survey using WIYN/NEID observations. We find that TOI-6054b and

Revised Masses for Low-density Planets Orbiting the Disordered M-dwarf System TOI-1266
The Astronomical JournalWe present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two known transiting sub-Neptunes at 10.8 and 18.8 days.

Exoplanet Direct Imaging Detection Metrics and Exoplanet Populations
, 2018 Exoplanets commonly occur and have been detected using a variety of techniques over the past thirty years. The newer direct imaging detection technique has already provided unique data and will continue to generate discoveries as instrumentation improves.

Impact of Climate States and Seasons on Future Exo-Earth Observations
The Astrophysical JournalMany planetary parameters impact the climate state of Earth-like exoplanets and could vary significantly from those on Earth. However, some of these parameters may be impossible to observe, causing ambiguity in determining exoplanet climate and ...

Single Transit Detection in Kepler with Machine Learning and Onboard Spacecraft Diagnostics
The Astronomical JournalExoplanet discovery at long orbital periods requires reliably detecting individual transits without additional information about the system. Common techniques, like phase folding of light curves and periodogram analysis of radial velocity data, are more ...

Exploring Long-period Architectures: Four New Planet Candidates from Kepler with Periods >342 days
The Astronomical JournalThe Kepler detection pipeline, as well as the transit method, have a bias towards shorter periods, leaving a dearth of detections at longer orbital periods. This relative lack of detections has left an incomplete picture of the architectures of exoplanet
