Revisiting the unification of tidal disruption events with polarimetry
H. C. I. Wichern, G. Leloudas, M. Pursiainen +10
Tidal disruptions of stars by supermassive black holes produce multi-wavelength emission, of which the optical emission is of ambiguous origin. A unification scenario of tidal disr…
SN 2021tsz: A luminous, short photospheric phase Type II supernova in a low-metallicity host
R. Dastidar, G. Pignata, N. Dukiya +14
We present the analysis of the luminous Type II Supernova (SN) 2021tsz, which exploded in a low-luminosity galaxy. It reached a peak magnitude of -18.88 0.13 mag in the b…
Long-term evolution of the SN 2009ip-like transient SN 2016cvk
K. Matilainen, E. Kankare, S. Mattila +21
The interacting transient SN 2016cvk (ASASSN-16jt) is a member of the peculiar SN 2009ip-like events. We present our follow-up data and aim to draw conclusions about the physical n…
SN 2024abfo: a partially stripped SN II from a yellow supergiant
A. Reguitti, A. Pastorello, S. J. Smartt +35
We present photometric and spectroscopic data of the type IIb supernova (SN) 2024abfo in NGC 1493 (at 11 Mpc). The ATLAS survey discovered the object just a few hours after the exp…
A long-lasting eruption heralds SN 2023ldh, a clone of SN 2009ip
A. Pastorello, A. Reguitti, L. Tartaglia +46
We discuss the results of the spectroscopic and photometric monitoring of the type IIn supernova (SN) 2023ldh. Survey archive data show that the SN progenitor experienced some erra…
The bright long-lived Type II SN 2021irp powered by aspherical circumstellar material interaction (II): Estimating the CSM mass and geometry with polarimetry and light curve modeling
T. M. Reynolds, T. Nagao, K. Maeda +7
There is evidence for interaction between supernova (SN) ejecta and massive circumstellar material (CSM) in various types of SNe. The mass-ejection mechanisms that produce massive…
