The stellar to sub-stellar masses transition in 47 Tuc
C. Ventura, M. Tailo, P. Ventura +4
Context: The study of the Globular Cluster 47 Tuc offers the opportunity to shed new light on the debated issue on the presence of multiple populations in Globular Clusters, as rec…
The hydrogen-free circumstellar interaction in the Type Ib supernova 2021efd: A clue to the mechanism of the helium-layer stripping
N. Pyykkinen, T. Nagao, H. Kuncarayakti +27
Stripped-envelope supernovae (SESNe), including Type IIb, Ib, and Ic supernovae (SNe), originate from the explosions of massive stars whose outer envelopes have been largely remove…
SN 2022ngb: A faint, slowly evolving Type IIb supernova with a low-mass envelope
J. -W. Zhao, S. Benetti, Y. -Z. Cai +35
An extensive photometric and spectroscopic follow-up campaign of the Type IIb SN 2022ngb is presented in the article. Through detailed modeling of this dataset, we aim to constrain…
Newborn jet in the symbiotic system R Aquarii
T. Liimets, D. P. K. Banerjee, M. Santander-García +12
R Aquarii (R Aqr) is a well-known symbiotic binary that has attracted renewed interest during its recent periastron passage, an event that occurs only once every about 40 years. Th…
LRPayne: Stellar parameters and abundances from low-resolution spectra
Nagaraj Vernekar, Lorenzo Spina, Sara Lucatello +4
Aims. This paper introduces LRPayne, a novel algorithm designed for the efficient determination of stellar parameters and chemical abundances from low-resolution optical spectra, w…
SN 2016iog: A fast declining Type II-L supernova with an ultra-faint tail, persistently interacting with circumstellar material
Z. -H. Peng, S. Benetti, Y. -Z. Cai +26
We present optical photometric and spectroscopic observations of the rapidly declining Type IIL supernova (SN) 2016iog. SN 2016iog reached its peak 14 days after explosion,…
