Stability analysis of three exoplanet systems
J. P. Marshall, J. Horner, R. A. Wittenmyer +2
The orbital solutions of published multi-planet systems are not necessarily dynamically stable on timescales comparable to the lifetime of the system as a whole. For this reason, d…
TOI-954 b and K2-329 b: Short-Period Saturn-Mass Planets that Test whether Irradiation Leads to Inflation
Lizhou Sha, Chelsea X. Huang, Avi Shporer +70
We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, , ) observed in TESS sectors 4 and 5…
TOI-481 b & TOI-892 b: Two long period hot Jupiters from the Transiting Exoplanet Survey Satellite
Rafael Brahm, Louise D. Nielsen, Robert A. Wittenmyer +75
We present the discovery of two new 10-day period giant planets from the Transiting Exoplanet Survey Satellite () mission, whose masses were precisely determined using a wide…
The impact of unresolved magnetic spots on high precision radial velocity measurements
Maksym Lisogorskyi, Sudeshna Boro Saikia, Sandra V. Jeffers +6
The Doppler method of exoplanet detection has been extremely successful, but suffers from contaminating noise from stellar activity. In this work a model of a rotating star with a…
A planet within the debris disk around the pre-main-sequence star AU Microscopii
Peter Plavchan, Thomas Barclay, Jonathan Gagné +84
AU Microscopii (AU Mic) is the second closest pre main sequence star, at a distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively rare and spat…
AU Mic b is the Youngest Planet to have a Spin-Orbit Alignment Measurement
Brett C. Addison, Jonathan Horner, Robert A. Wittenmyer +20
We report measurements of the sky-projected spin-orbit angle for AU\,Mic\,b, a Neptune-size planet orbiting a very young (\,Myr) nearby pre-main sequence M dwarf star which…
