From Hubble to HWO: Bridging the Frontier of White Dwarf Exoplanet Science

Laura K. Rogers, Siyi Xu, Martin Barstow +20

White dwarf stars, the endpoint of stellar evolution for 97% of stars in our Milky Way, offer a unique and powerful window into the bulk elemental composition of rocky exoplanetary…

The Morphology of Asteroidal Dust Around White Dwarf Stars: Optical and Near-infrared Pulsations in G29-38

T. von Hippel, J. Farihi, J. L. Provencal +20

More than 36 years have passed since the discovery of the infrared excess from circumstellar dust orbiting the white dwarf G29-38, which at 17.5 pc it is the nearest and brightest…

Profound optical flares from the relativistic jets of active galactic nuclei

Gopal Bhatta, Staszek Zola, M. Drozdz +11

Intense outbursts in blazars are among the most extreme phenomena seen in extragalactic objects. Studying these events can offer important information about the energetic physical…

The bright blue side of the night sky: Spectroscopic survey of bright and hot (pre-) white dwarfs

Nicole Reindl, Ramazan Islami, Klaus Werner +10

We report on the spectroscopic confirmation of 68 new bright ( mag) and blue (pre-)white dwarfs (WDs). This finding has allowed us to almost double the number of the h…

Catching profound optical flares in blazars

Gopal Bhatta, Staszek Zola, M. Drozdz +11

Flaring episodes in blazars represent one of the most violent processes observed in extra-galactic objects. Studies of such events shed light on the energetics of the physical proc…

Kepler and TESS Observations of PG 1159-035

Gabriela Oliveira da Rosa, S. O. Kepler, Alejandro H. Córsico +11

PG 1159-035 is the prototype of the DOV hot pre-white dwarf pulsators. It was observed during the Kepler satellite K2 mission for 69 days in 59 s cadence mode and by the TESS satel…
