The Extremely Metal-Poor SN 2023ufx: A Local Analog to High-Redshift Type II Supernovae

Michael A. Tucker, Jason Hinkle, Charlotte R. Angus +26

We present extensive observations of the Type II supernova (SN II) 2023ufx which is likely the most metal-poor SN II observed to-date. It exploded in the outskirts of a low-metalli…

SN 2020pvb: a Type IIn-P supernova with a precursor outburst

Nancy Elias-Rosa, Seán J. Brennan, Stefano Benetti +37

We present photometric and spectroscopic data sets for SN 2020pvb, a Type IIn-P supernova (SN) similar to SNe 1994W, 2005cl, 2009kn and 2011ht, with a precursor outburst detected (…

SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS

Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28

The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…

Type II-P Supernova Progenitor Star Initial Masses and SN 2020jfo: Direct Detection, Light Curve Properties, Nebular Spectroscopy, and Local Environment

Charles D. Kilpatrick, Luca Izzo, Rory O. Bentley +23

We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at 14.5 Mpc. This wealth of multiwavelength data allows to compare different metrics com…

Observations of the luminous red nova AT 2021biy in the nearby galaxy NGC 4631

Y. -Z. Cai, A. Pastorello, M. Fraser +73

We present an observational study of the luminous red nova (LRN) AT\,2021biy in the nearby galaxy NGC\,4631. The field of the object was routinely imaged during the pre-eruptive st…

Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV

A. Pastorello, G. Valerin, M. Fraser +77

We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…

The NIR Ca II triplet at low metallicity - Searching for extremely low-metallicity stars in classical dwarf galaxies

Else Starkenburg, Vanessa Hill, Eline Tolstoy +9

The NIR Ca II triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group, providing a better…
