The radioactive isotopes 44 Ti and 56 Ni are important products of explosive
nucleosynthesis, which play a key role in supernova (SN) diagnostics and have been …

Neutrino-neutrino scattering could have a large secret component that would turn neutrinos
within a supernova (SN) core into a self-coupled fluid. Neutrino transport within the SN core …

Sterile neutrinos with masses up to O (100) MeV can be copiously produced in a supernova
(SN) core through the mixing with active neutrinos. In this regard, the SN 1987A detection of …

Protoneutron stars formed during core-collapse supernovae are hot and dense
environments that contain a sizable population of muons. If these interact with new long …

A bstract Light hypothetical particles with masses up to\(\mathcal {O}(100)\) MeV can be
produced in the core of supernovae. Their subsequent decays to neutrinos can produce a …

Axionlike particles (ALPs) coupled to nucleons might be copiously emitted from a supernova
(SN) core. We extend existing bounds on free-streaming ALPs to the case in which these are …

The large distances travelled by neutrinos emitted from the Sun and core-collapse
supernovae together with the characteristic energy of such neutrinos provide ideal …

A bstract Solar nuclear reactions can occasionally produce sub-MeV elusive beyond the
Standard Model particles that escape the solar interior without further interactions. This study …

The next Milky Way supernova will be an epochal event in multimessenger astronomy,
critical to tests of supernovae, neutrinos, and new physics. Realizing this potential depends …

A core-collapse supernova (SN) releases almost all of its energy in the form of neutrinos,
which provide a unique opportunity to probe the working machinery of an SN. These sites …
