HD 76920b pinned down: a detailed analysis of the most eccentric planetary system around an evolved star
C. Bergmann, M. I. Jones, J. Zhao +9
We present 63 new multi-site radial velocity measurements of the K1III giant HD 76920, which was recently reported to host the most eccentric planet known to orbit an evolved star.…
Cluster Difference Imaging Photometric Survey. II. TOI 837: A Young Validated Planet in IC 2602
L. G. Bouma, J. D. Hartman, R. Brahm +42
We report the discovery of TOI 837b and its validation as a transiting planet. We characterize the system using data from the NASA TESS mission, the ESA Gaia mission, ground-based…
Very regular high-frequency pulsation modes in young intermediate-mass stars
Timothy R. Bedding, Simon J. Murphy, Daniel R. Hey +33
Asteroseismology is a powerful tool for probing the internal structures of stars by using their natural pulsation frequencies. It relies on identifying sequences of pulsation modes…
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…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
Veloce Rosso: Australia's new precision radial velocity spectrograph
James Gilbert, Christoph Bergmann, Gabe Bloxham +24
Veloce is an ultra-stable fibre-fed R4 echelle spectrograph for the 3.9 m Anglo-Australian Telescope. The first channel to be commissioned, Veloce 'Rosso', utilises multiple low-co…
