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…

PB 8783: the first sdO star suitable for asteroseismic modeling?

Valerie Van Grootel, Suzanna K. Randall, Marilyn Latour +5

Pulsating hot B subdwarf (sdB) stars, which are core-He burning objects, are one of the showcases of asteroseismology. Thanks to the combination of rich pulsation spectra and state…

Discovery of a second pulsating intermediate helium-enriched sdOB star

M. Latour, E. M. Green, G. Fontaine

We present the discovery of long-period, low-amplitude, g-mode pulsations in the intermediate He-rich hot subdwarf (sdOB) star Feige 46. Up until now only one other He-enriched sdO…
