Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
TESS first look at evolved compact pulsators : Discovery and asteroseismic probing of the g-mode hot B subdwarf pulsator EC 21494-7018
S. Charpinet, P. Brassard, G. Fontaine +29
We present the discovery and asteroseismic analysis of a new g-mode hot B subdwarf (sdB) pulsator, EC 21494-7018 (TIC 278659026), monitored in TESS first sector using 120-second ca…
On the existence of warm H-rich pulsating white dwarfs
Leandro G. Althaus, Alejandro H. Córsico, Murat Uzundag +8
The possible existence of warm ( K) pulsating DA white dwarf (WD) stars, hotter than ZZ Ceti stars, was predicted in theoretical studies more than 30 yr ago…
TESS first look at evolved compact pulsators: asteroseismology of the pulsating helium-atmosphere white dwarf TIC 257459955
Keaton J. Bell, Alejandro H. Córsico, Agnès Bischoff-Kim +10
Pulsation frequencies reveal the interior structures of white dwarf stars, shedding light on the properties of these compact objects that represent the final evolutionary stage of…
A White Dwarf with Transiting Circumstellar Material Far Outside the Roche Limit
Z. Vanderbosch, J. J. Hermes, E. Dennihy +9
We report the discovery of a white dwarf exhibiting deep, irregularly shaped transits, indicative of circumstellar planetary debris. Using Zwicky Transient Facility DR2 photometry…
Bayesian hierarchical inference of asteroseismic inclination angles
James S. Kuszlewicz, William J. Chaplin, Thomas S. H. North +5
The stellar inclination angle-the angle between the rotation axis of a star and our line of sight-provides valuable information in many different areas, from the characterisation o…
KOI-3890: A high mass-ratio asteroseismic red-giantM-dwarf eclipsing binary undergoing heartbeat tidal interactions
James S. Kuszlewicz, Thomas S. H. North, William J. Chaplin +9
KOI-3890 is a highly eccentric, 153-day period eclipsing, single-lined spectroscopic binary system containing a red-giant star showing solar-like oscillations alongside tidal inter…
