TESS observations of the Pleiades cluster: a nursery for delta Scuti stars
Timothy R. Bedding, Simon J. Murphy, Courtney Crawford +8
We studied 89 A- and F-type members of the Pleiades open cluster, including five escaped members. We measured projected rotational velocities (v sin i) for 49 stars and confirmed t…
A non-interacting Galactic black hole candidate in a binary system with a main-sequence star
Sukanya Chakrabarti, Joshua D. Simon, Peter A. Craig +10
We describe the discovery of a solar neighborhood (d=468 pc) binary system with a main-sequence sunlike star and a massive non-interacting black hole candidate. The spectral energy…
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…
Revisiting bright delta Scuti stars and their period-luminosity relation with TESS and Gaia DR3
Natascha Barac, Timothy R. Bedding, Simon J. Murphy +1
We have used NASA's TESS mission to study catalogued delta Scuti stars. We examined TESS light curves for 434 stars, including many for which few previous observations exist. We fo…
Discovery of post-mass-transfer helium-burning red giants using asteroseismology
Yaguang Li, Timothy R. Bedding, Simon J. Murphy +14
A star expands to become a red giant when it has fused all the hydrogen in its core into helium. If the star is in a binary system, its envelope can overflow onto its companion or…
