SN 2024afyu interpreted as a Pair Instability Supernova
P. J. Pessi, S. Barmentloo, Ł. Wyrzykowski +63
Pair-instability supernovae (PISNe) are the predicted explosions of very massive stars triggered by electron-positron pair production. Numerous transients have been proposed as PIS…
Nebular Phase Evolution of SN 2023ixf (I): From Circumstellar Infrared Echo to the onset of in-situ Dust Formation in a Type II Supernova
Avinash Singh, S. Goto, A. Sarangi +58
We present optical and near-infrared (NIR) photometric and spectroscopic observations of the Type II supernova SN 2023ixf spanning 150 to 750 days, combined with published early-ti…
A New FU Orionis Accretion Outburst in the W5 HII Region
Lynne A. Hillenbrand, Matthew J. Graham, Mansi M. Kasliwal +9
We announce a recently detected outburst that is currently only a few months old, and probably of FU Orionis type. The progenitor to the outburst was an emission-line, flat-spectru…
Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission
Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…
A half-ring of ionized circumstellar material trapped in the magnetosphere of a white dwarf merger remnant
Andrei A. Cristea, Ilaria Caiazzo, Tim Cunningham +31
Many white dwarfs are observed in compact double white dwarf binaries and, through the emission of gravitational waves, a large fraction are destined to merge. The merger remnants…
Direct detection of supernova progenitor stars with ZTF and LSST
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +9
The direct detection of core-collapse supernova (SN) progenitor stars is a powerful way of probing the last stages of stellar evolution. However, detections in archival Hubble Spac…
Zwicky Transient Facility and Globular Clusters: Calibration of the gr-Band Absolute Magnitudes for the Yellow Post-Asymptotic-Giant-Branch Stars
Chow-Choong Ngeow, Anupam Bhardwaj, Daniel Reiley +3
We present the first absolute calibration for the yellow post-asymptotic-giant-branch (PAGB) stars in the g- and r-band based on time-series observations from the Zwicky Transient…
Zwicky Transient Facility and Globular Clusters: The Period-Luminosity and Period-Wesenheit Relations for Type II Cepheids
Chow-Choong Ngeow, Anupam Bhardwaj, Jing-Yi Henderson +5
We present the first gri-band period-luminosity (PL) and period-Wesenheit (PW) relations for 37 Type II Cepheids (hereafter TIIC) located in 18 globular clusters based on photometr…
