OrCAS: Origins, Compositions, and Atmospheres of Sub-neptunes. I. Survey Definition
Ian J. M. Crossfield, Alex S. Polanski, Paul Robertson +61
Sub-Neptunes - volatile-rich exoplanets smaller than Neptune - are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well a…
The impact of observing cadence and undetected companions on the accuracy of planet mass measurements from radial velocity monitoring
Joseph M. Akana Murphy, Rafael Luque, Natalie M. Batalha
We conduct experiments on both real and synthetic radial velocity (RV) data to quantify the impact that observing cadence, the number of RV observations, and undetected companions…
HD 119130 b is not an "ultra-dense" sub-Neptune
Joseph M. Akana Murphy, Rafael Luque, Natalie M. Batalha +13
We present a revised mass measurement for HD 119130 b (aka K2-292 b), a transiting planet ( days, ) orbiting a chro…
Revised Masses for Low Density Planets Orbiting the Disordered M-dwarf System TOI-1266
Dakotah Tyler, Erik A. Petigura, James Rogers +5
We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two transiting sub-Neptunes at 10.8 an…
Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs
Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas +42
Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasing…
Utilizing Photometry from Multiple Sources to Mitigate Stellar Variability in Precise Radial Velocities: A Case Study of Kepler-21
Corey Beard, Paul Robertson, Mark R. Giovinazzi +26
We present a new analysis of Kepler-21, the brightest (V = 8.5) Kepler system with a known transiting exoplanet, Kepler-21 b. Kepler-21 b is a radius valley planet ($R = 1.6\pm 0.2…
