Physical properties of long-rising type II supernovae -- Bayesian analytic modeling and spectrophotometric correlations

S. P. Cosentino, C. Inserra, M. L. Pumo

Supernova (SN) 1987A, with its long-rising (40 days) light curve, defines a rare subclass of type II SNe known as 1987A-like events. Representing only 1-3 percent of all c…

Light-Curve and Spectral Properties of Type II Supernovae from the ATLAS survey

K. Ertini, J. P. Anderson, G. Folatelli +22

Type II supernovae (SNe II) are the most common terminal stellar explosions in the Universe. With SNe now being detected within days after explosion, there is growing evidence that…

ExoClock Project IV: A homogeneous catalogue of 620 updated exoplanet ephemerides

A. Kokori, A. Tsiaras, G. Pantelidou +323

The ExoClock project is an open platform aiming to monitor exoplanets by integrating observations from space and ground based telescopes. This study presents an updated catalogue o…

SN 2021aaev: a Hydrogen-Rich Superluminous Supernova with Early Flash and Long-Lived Circumstellar Interaction in an Unusual Host Environment

Yang Hu, Ragnhild Lunnan, Priscila J. Pessi +25

We present photometric and spectroscopic observations of SN\,2021aaev, a hydrogen-rich, superluminous supernova with persistent (at least days) narrow Balmer lines (SLSN-…

High-Energy Neutrinos by Hydrogen-rich Supernovae interacting with low-massive Circumstellar Medium: The Case of SN 2023ixf

S. P. Cosentino, M. L. Pumo, S. Cherubini

In hydrogen-rich (H-rich) Supernova (SN) events, the collision between the H-rich ejecta and the Circum-Stellar Medium (CSM) can accelerate particles and produce high-energy neutri…

Long-rising Type II supernovae resembling supernova 1987A -- II. A new analytical model to describe these events

M. L. Pumo, S. P. Cosentino

With the aim of improving our knowledge on supernova (SN) 1987A-like objects and, more in general, on H-rich SNe, we have developed a new analytic model to describe their post-expl…
