A 5.3-minute-period pulsing white dwarf in a binary detected from radio to X-rays

Ingrid Pelisoli, T. R. Marsh, David A. H. Buckley +19

White dwarf stars are the most common stellar fossils. When in binaries, they make up the dominant form of compact object binary within the Galaxy and can offer insight into differ…

Asteroseismology of PG 1541651 and BPM 31594 with TESS

Alejandra D. Romero, Gabriela Oliveira da Rosa, S. O. Kepler +5

We present the photometric data from TESS for two known ZZ Ceti stars, PG 1541+651 and BPM 31594. Before TESS, both objects only had observations from short runs from ground-based…

The impact of the uncertainties in the 12C(α,γ)16O reaction rate on the evolution of low- to intermediate-mass stars

Ben T. Pepper, A. G. Istrate, A. D. Romero +1

One of the largest uncertainties in stellar evolutionary computations is the accuracy of the considered reaction rates. The 12C(alpha,gamma)16O reaction is particularly important f…

Discovery of 74 new bright ZZ Ceti stars in the first three years of TESS

A. D. Romero, S. O. Kepler, J. J. Hermes +17

We report the discovery of 74 new pulsating DA white dwarf stars, or ZZ Cetis, from the data obtained by the Transiting Exoplanet Survey Satellite (TESS) mission, from Sectors 1 to…

White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 16

S. O. Kepler, Detlev Koester, Ingrid Pelisoli +2

White dwarfs are the end state of the evolution of more than 97% of all stars, and therefore carry information on the structure and evolution of the Galaxy through their luminosity…

The pulsating white dwarf G117-B15A: still the most stable optical clock known

S. O. Kepler, D. E. Winget, Zachary P. Vanderbosch +14

The pulsating hydrogen atmosphere white dwarf star G 117-B15A has been observed since 1974. Its main pulsation period at 215.19738823(63) s, observed in optical light curves, varie…
