Automatic Spectroscopic Data Reduction using BANZAI
Curtis McCully, Matthew Daily, G. Mirek Brandt +3
Time domain astronomy has both increased the data volume and the urgency of data reduction in recent years. Spectra provide key insights into astrophysical phenomena but require co…
Three low-mass companions around aged stars discovered by TESS
Zitao Lin, Tianjun Gan, Sharon X. Wang +42
We report the discovery of three transiting low-mass companions to aged stars: a brown dwarf (TOI-2336b) and two objects near the hydrogen burning mass limit (TOI-1608b and TOI-252…
The PEPSI Exoplanet Transit Survey (PETS). II. A Deep Search for Thermal Inversion Agents in KELT-20 b/MASCARA-2 b with Emission and Transmission Spectroscopy
Marshall C. Johnson, Ji Wang, Anusha Pai Asnodkar +19
Recent observations have shown that the atmospheres of ultra hot Jupiters (UHJs) commonly possess temperature inversions, where the temperature increases with increasing altitude.…
Nodal Precession and Tidal Evolution of Two Hot-Jupiters: WASP-33 b and KELT-9 b
Alexander P. Stephan, Ji Wang, P. Wilson Cauley +4
Hot Jupiters orbiting rapidly rotating stars on inclined orbits undergo tidally induced nodal precession measurable over several years of observations. The Hot Jupiters WASP-33 b a…
Nodal Precession of WASP-33b for Eleven Years by Doppler Tomographic and Transit Photometric Observations
Noriharu Watanabe, Norio Narita, Enric Palle +14
WASP-33b, a hot Jupiter around a hot star, is a rare system in which nodal precession has been discovered. We updated the model for the nodal precession of WASP-33b by adding new o…
A Radial Velocity Study of the Planetary System of Pi Mensae: Improved Planet Parameters for PI Mensae c and a Third Planet on a 125-d Orbit
Artie P. Hatzes, Davide Gandolfi, Judith Korth +33
Pi Men hosts a transiting planet detected by the TESS space mission and an outer planet in a 5.7-yr orbit discovered by RV surveys. We studied this system using new radial velocity…
