The Discovery of K2-232c: Divergent Formation Histories for Hot and Warm Jupiters Based on Outer Companion Eccentricity
Jessica A. Ranshaw, Xian-Yu Wang, Jennifer A. Burt +6
Ever since their discovery, hot Jupiters have been one of the most studied types of exoplanets to exist thanks to their significant size, their proximity to their host star, and th…

Radial Velocity Evidence for a Post-Mass-Transfer Massive Binary System NaSt1
Kittipong Wangnok, Samaporn Tinyanont, Ryan M. Lau +11
We present multi-epoch high-resolution optical spectroscopy () of the emission-line object NaSt1 to test its proposed binary nature, along with long-term multiba…

Exploring the robustness of Keplerian signals to the removal of active and telluric features
Maksym Lisogorskyi, Hugh R. A. Jones, Fabo Feng +2
We examine the influence of activity- and telluric-induced radial velocity signals on high resolution spectra taken with an iodine absorption cell. We exclude 2 Angstrom spectral c…
