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…

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…

Core crystallization and pile-up in the cooling sequence of evolving white dwarfs

Pier-Emmanuel Tremblay, Gilles Fontaine, Nicola Pietro Gentile Fusillo +7

White dwarfs are stellar embers depleted of nuclear energy sources that cool over billions of years. These stars, which are supported by electron degeneracy pressure, reach densiti…

A new class of pulsating hot subdwarfs

Thomas Kupfer, Evan B. Bauer, Kevin B. Burdge +22

Using high-cadence observations from the Zwicky Transient Facility at low Galactic latitudes, we have discovered a new class of pulsating, hot, compact stars. We have found four ca…
