A Catalogue of Solar-Like Oscillators Observed by TESS in 120-second and 20-second Cadence
Emily Hatt, Martin B. Nielsen, William J. Chaplin +12
The Transiting Exoplanet Survey Satellite (TESS) mission has provided photometric light curves for stars across nearly the entire sky. This allows for the application of asteroseis…
HD-TESS: An Asteroseismic Catalog of Bright Red Giants within TESS Continuous Viewing Zones
Marc Hon, James S. Kuszlewicz, Daniel Huber +2
We present HD-TESS, a catalog of 1,709 bright () red giants from the Henry Draper (HD) Catalog with asteroseismic measurements based on photometry from NASA's Transiting…
A prescription for the asteroseismic surface correction
Yaguang Li, Timothy R. Bedding, Dennis Stello +11
In asteroseismology, the surface effect refers to a disparity between the observed and the modelled frequencies in stars with solar-like oscillations. It originates from improper m…
Integrated Mass Loss of Evolved Stars in M4 using Asteroseismology
Madeline Howell, Simon W. Campbell, Dennis Stello +1
Mass loss remains a major uncertainty in stellar modelling. In low-mass stars, mass loss is most significant on the red giant branch (RGB), and will impact the star's evolutionary…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
Polarimetric detection of nonradial oscillation modes in the beta Cephei star beta Crucis
Daniel V. Cotton, Derek L. Buzasi, Conny Aerts +11
Here we report the detection of polarization variations due to nonradial modes in the beta Cephei star beta Crucis. In so doing we confirm 40-year-old predictions of pulsation-indu…
