PBjam: A Python package for automating asteroseismology of solar-like oscillators
M. B. Nielsen, G. R. Davies, W. H. Ball +14
Asteroseismology is an exceptional tool for studying stars by using the properties of observed modes of oscillation. So far the process of performing an asteroseismic analysis of a…
Differential Modelling Systematics across the HR Diagram from Asteroseismic Surface Corrections
J. M. Joel Ong, Sarbani Basu, Jean M. McKeever
Localised modelling error in the near-surface layers of evolutionary stellar models causes the frequencies of their normal modes of oscillation to differ from those of actual stars…
Robust asteroseismic properties of the bright planet host HD 38529
Warrick H. Ball, William J. Chaplin, Martin B. Nielsen +21
The Transiting Exoplanet Survey Satellite (TESS) is recording short-cadence, high duty-cycle timeseries across most of the sky, which presents the opportunity to detect and study o…
Semi-analytic Expressions for the Isolation and Coupling of Mixed Modes
J. M. Joel Ong, Sarbani Basu
In the oscillation spectra of giant stars, nonradial modes may be seen to undergo avoided crossings, which produce a characteristic "mode bumping" of the otherwise uniform asymptot…
EXPRES I. HD~3651 an Ideal RV Benchmark
John M. Brewer, Debra A. Fischer, Ryan T. Blackman +10
The next generation of exoplanet-hunting spectrographs should deliver up to an order of magnitude improvement in radial velocity precision over the standard 1 m/s state of the art.…
TESS Asteroseismic Analysis of the Known Exoplanet Host Star HD 222076
Chen Jiang, Timothy R. Bedding, Keivan G. Stassun +24
The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission aiming to search for exoplanets that transit bright stars. The high-quality photometric data of TESS a…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
An Extreme Precision Radial Velocity Pipeline: First Radial Velocities from EXPRES
Ryan R. Petersburg, J. M. Joel Ong, Lily L. Zhao +13
The EXtreme PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, , optical spectrograph. It was recently commissioned at the 4.3-m Lowell Discove…
Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi
William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81
Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…
