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…
Dust Formation in Common Envelope Binary Interactions -- III. Lightcurves
Chunliang Mu, Orsola De Marco, Luis C. Bermúdez-Bustamante +6
Luminous red novae are transient events thought to arise from common envelope binary interactions. In this paper, we perform post-processing light-curve calculations for two, 3D hy…
Comparative Study of Two Luminous Red Novae I. Progenitor Modeling and Dust Formation
M. Wavasseur, N. Blagorodnova, M. A. Gómez-Muñoz +1
Luminous red novae are astrophysical transients associated with unstable mass transfer in interacting binaries and are commonly interpreted as outcomes of common-envelope evolution…
XP-TEAL: Gaia XP Tool for Emission and Absorption Lines II. Gaia-HELIX catalogue of H emitters in Gaia BP/RP spectra
S. Malhotra, M. Weiler, F. Anders +9
Context: With Gaia's third Data Release (DR3), low-resolution BP/RP (XP) spectra became available for more than 219 million sources. In previous work, we developed a fast method fo…
Red novae, their progenitors, and remnants
Tomasz Kaminski, Nadejda Blagorodnova
Red novae or luminous red novae are a class of optical transients that have emerged over the past two decades. They occupy an intermediate luminosity regime between classical novae…
A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
