Magnetic field and chromospheric activity evolution of HD75332: a rapid magnetic cycle in an F star without a hot Jupiter
E. L. Brown, S. C. Marsden, M. W. Mengel +10
Studying cool star magnetic activity gives an important insight into the stellar dynamo and its relationship with stellar properties, as well as allowing us to place the Sun's magn…
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…
