Abstract NASA’s Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited sample transiting suitable for population studies. Assembling such a requires confirming hundreds planet candidates with additional follow-up observations. Here we present 20 that were detected using TESS data and confirmed be planets through photometric, spectroscopic, imaging observations coordinated the Follow-up Observing...
ABSTRACT We present the discovery and characterization of six short-period, transiting giant planets from NASA’s Transiting Exoplanet Survey Satellite (TESS) -- TOI-1811 (TIC 376524552), TOI-2025 394050135), TOI-2145 88992642), TOI-2152 395393265), TOI-2154 428787891), TOI-2497 97568467). All orbit bright host stars (8.9 <G < 11.8, 7.7 <K 10.1). Using a combination time-series photometric spectroscopic follow-up observations TESS Follow-up Observing Program Working...
We present a unique implementation of Python coding in an asynchronous object-oriented programming (OOP) framework to fully automate the process collecting data with George Mason University (GMU) Observatory's 0.8-meter telescope. The goal this project is perform automated follow-up observations for Transiting Exoplanet Survey Satellite (TESS) mission, while still allowing human control, monitoring, and adjustments. Prior our implementation, facility was computer-controlled by observer...
