Soumagnac,Paula Szkody,Charlotte Ward +25 more
TL;DR: In this article, a new class of pulsating, hot compact stars was discovered, exhibiting blue colors (g − r ≤ −0.1 mag), pulsation amplitudes of > 5%, and pulsation periods of 200-475 s.

TL;DR: In this paper, the authors presented ZTF20aajnksq (AT 2020blt), a fast-fading (Δr = 2.3 mag in Δt = 1.3 days) red (g − r ≈ 0.6 mag) and luminous (M1626 A = −25.9 mag) optical transient at z = 0.9 discovered by ZTF.
Journal ArticleDOI
Year 1 of the ZTF high-cadence Galactic plane survey: strategy, goals, and early results on new single-mode hot subdwarf B-star pulsatos
Thomas Kupfer,Thomas Kupfer,Thomas A. Prince,Jan van Roestel,Eric C. Bellm,Lars Bildsten,Lars Bildsten,Michael W. Coughlin,Andrew J. Drake,Matthew J. Graham,Courtney Klein,Shrinivas R. Kulkarni,Frank J. Masci,Richard Walters,Igor Andreoni,Rahul Biswas,Corey W Bradshaw,Dmitry A. Duev,Richard Dekany,Joseph A. Guidry,J. J. Hermes,Russ R. Laher,Reed Riddle +22 more
TL;DR: The first results of the high-cadence Galactic plane survey using the Zwicky Transient Facility (ZTF) were presented in this paper, which revealed the Galactic population of short-period variable stars, including short period binaries and stellar pulsators with periods less than a few hours.
