The symphony of pulsations and binarity among massive stars using HERMES spectroscopy and TESS photometry
K. Thomson-Paressant, D. M. Bowman, F. Nardini +16
A wide range of variability mechanisms exist among intermediate mass and massive stars, which are not yet fully understood. Using complementary data sources for a large population…
AT 2022csn: A Photometrically Peculiar Optical/UV Tidal Disruption Event in a Type II AGN
Yael Dgany, Iair Arcavi, Grisha Zeltyn +18
The emission mechanism and host galaxy preference of optical/UV tidal disruption events (TDEs) are still not entirely understood. We present observations of the TDE AT 2022csn, whi…
Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd
Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38
The paper reports multi-wavelength observations of tidal disruption event 2024aepd, revealing an early near‑infrared excess and a rapid transition from a thermal X‑ray disk to a ha…
Type Ib supernovae are bluer than Type Ic supernovae
Harim Jin, Selma E. de Mink, Sebastian Holzner +5
The study finds that Type Ib supernovae are systematically bluer at peak than Type Ic supernovae, suggesting intrinsic differences in progenitor stripping rather than host galaxy r…
Superlinear Type II Superluminous Supernovae 2017fck and 2019cmv: A Possible Origin from Interacting Thermonuclear Supernovae
Daichi Hiramatsu, Takashi J. Moriya, D. Andrew Howell +9
Additional power sources to traditional supernovae (SNe) are necessary to account for the extreme luminosities of superluminous SNe (SLSNe). A main power source for hydrogen-rich S…
SN 2020bij and a Possible Slow-Rise High-Velocity Subclass of Type IIP Supernovae
Sondos Mohsen-Tanev, Iair Arcavi, Shahar Bracha +17
Mapping how the explosion properties of Type II supernovae (SNe II) relate to the properties of their progenitors can provide strong constraints for understanding the final evoluti…
