Spinning up a Daze: TESS Uncovers a Hot Jupiter orbiting the Rapid-Rotator TOI-778
Jake Clark, Brett Addison, Jack Okumura +68
NASA's Transiting Exoplanet Survey Satellite (TESS) mission, has been uncovering a growing number of exoplanets orbiting nearby, bright stars. Most exoplanets that have been discov…
A sub-Neptune transiting the young field star HD 18599 at 40 pc
Jerome P. de Leon, John H. Livingston, James S. Jenkins +67
Transiting exoplanets orbiting young nearby stars are ideal laboratories for testing theories of planet formation and evolution. However, to date only a handful of stars with age <…
The GALAH Survey: Improving our understanding of confirmed and candidate planetary systems with large stellar surveys
Jake T. Clark, Duncan J. Wright, Robert A. Wittenmyer +24
Pioneering photometric, astrometric, and spectroscopic surveys are helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy, and the p…
TOI-1431b/MASCARA-5b: A Highly Irradiated Ultra-Hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars
Brett Christopher Addison, Emil Knudstrup, Ian Wong +70
We present the discovery of a highly irradiated and moderately inflated ultra-hot Jupiter, TOI-1431b/MASCARA-5b (HD 201033b), first detected by NASA's Transiting Exoplanet Survey S…
The GALAH Survey: Using Galactic Archaeology to Refine our Knowledge of TESS Target Stars
Jake T. Clark, Mathieu Clerte, Natalie R. Hinkel +29
An unprecedented number of exoplanets are being discovered by the Transiting Exoplanet Survey Satellite (TESS). Determining the orbital parameters of these exoplanets, and especial…
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…
K2-HERMES II. Planet-candidate properties from K2 Campaigns 1-13
Robert A. Wittenmyer, Jake T. Clark, Sanjib Sharma +22
Accurate and precise radius estimates of transiting exoplanets are critical for understanding their compositions and formation mechanisms. To know the planet, we must know the host…
TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star
Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91
We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…
The Pan-Pacific Planet Search. VIII. Complete results and the occurrence rate of planets around low-luminosity giants
Robert A. Wittenmyer, R. P. Butler, Jonathan Horner +6
Our knowledge of the populations and occurrence rates of planets orbiting evolved intermediate-mass stars lags behind that for solar-type stars by at least a decade. Some radial ve…
The HD 181433 Planetary System: Dynamics and a New Orbital Solution
Jonathan Horner, Robert A Wittenmyer, Duncan J Wright +7
We present a detailed analysis of the orbital stability of the HD 181433 planetary system, finding it to exhibit strong dynamical instability across a wide range of orbital eccentr…
TESS Spots a Compact System of Super-Earths around the Naked-Eye Star HR 858
Andrew Vanderburg, Chelsea X. Huang, Joseph E. Rodriguez +48
Transiting Exoplanet Survey Satellite (TESS) observations have revealed a compact multi-planet system around the sixth-magnitude star HR 858 (TIC 178155732, TOI 396), located 32 pa…
Truly eccentric. II. When can two circular planets mimic a single eccentric orbit?
Robert A. Wittenmyer, Christoph Bergmann, Jonathan Horner +2
When, in the course of searching for exoplanets, sparse sampling and noisy data make it necessary to disentangle possible solutions to the observations, one must consider the possi…
Truly eccentric. I. Revisiting eight single-eccentric planetary systems
Robert A. Wittenmyer, Jake T. Clark, Jinglin Zhao +3
We examine eight known single-eccentric planetary systems in light of recently released large data archives and new analysis techniques. For four of these systems (HD 7449, HD 6521…
