Different to the core: the pre-supernova structures of massive single and binary-stripped stars [PDF]
Astronomy & Astrophysics, 2021 The majority of massive stars live in binary or multiple systems and will interact during their lifetimes, which helps to explain the observed diversity of core-collapse supernovae.

Muonic Boson Limits: Supernova Redux [PDF]
, 2021 We derive supernova (SN) bounds on muon-philic bosons, taking advantage of the recent emergence of muonic SN models. Our main innovations are to consider scalars $\phi$ in addition to pseudoscalars $a$ and to include systematically the generic two-photon

Supernovae and their scientific secrets
He jishu, 2023 Supernovae are the most gorgeous fireworks that people can observe in the universe. Their explosion can produce a maximum luminosity 10 billion times that of the Sun, helping scientists see farther.

SNEWS 2.0: a next-generation supernova early warning system for multi-messenger astronomy [PDF]
New Journal of Physics, 2020 The next core-collapse supernova in the Milky Way or its satellites will represent a once-in-a-generation opportunity to obtain detailed information about the explosion of a star and provide significant scientific insight for a variety of fields because ...

Swope Supernova Survey 2017a (SSS17a), the optical counterpart to a gravitational wave source [PDF]
Science, 2017 Photons from a gravitational wave event Two neutron stars merging together generate a gravitational wave signal and have also been predicted to emit electromagnetic radiation. When the gravitational wave event GW170817 was detected, astronomers rushed to

Improved axion emissivity from a supernova via nucleon-nucleon bremsstrahlung [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 The most efficient axion production mechanism in a supernova (SN) core is the nucleon-nucleon bremsstrahlung. This process has been often modeled at the level of the vacuum one-pion exchange (OPE) approximation. Starting from this naive recipe, we revise

The electron-capture origin of supernova 2018zd [PDF]
Nature Astronomy, 2020 In the transitional mass range (~8–10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture supernova.

A revised catalogue of 294 Galactic supernova remnants [PDF]
Journal of astrophysics and astronomy, 2019 A revised catalogue of Galactic supernova remnants (SNRs) is presented, along with some simple statistics of their properties. Six new SNRs have been added to the catalogue since the previous published version from 2014, and six entries have been removed,
