    “…Stellar model calculations for a 25 M$_\odot$ star show that the new data have a significant effect on the $s$-process production of $^{63}$Cu, $^{64}$Ni, and $^{64}$Zn in massive stars, allowing stronger constraints on the Cu yields from explosive nucleosynthesis in the subsequent supernova.…”

    “…We discuss that the availability of neutrino beams in the 100 MeV energy range offers a unique opportunity to perform neutrino scattering experiments of interest for nuclear physics, for the study of fundamental interactions and of core-collapse supernova physics.…”

    “…The physics program at the Gran Sasso Laboratory that we are defining will be focussed on the next phase of neutrino physics with a complementary set of experiments on the muon-neutrino beam from CERN (CNGS project), on solar neutrinos, on atmospheric neutrinos and on neutrinos from supernova explosion. The relevant thermonuclear cross-sections will be measured. …”

    “…We conduct a comprehensive study of the detectability of primordial black holes with non-negligible spin, via the searches for the neutrinos and positrons in the MeV energy range. Diffuse supernova neutrino background searches and observation of the 511 keV gamma-ray line from positrons in the Galactic center set competitive constraints. …”

    “…For instance, a strong limit on the Λ→na transition can be derived from the supernova SN 1987A. In the near future, dedicated searches for q→q′a decays at ongoing experiments could potentially test Peccei-Quinn breaking scales up to 1012  GeV at NA62 or KOTO and up to 109  GeV at Belle II or BES III.…”

    “…Recent observations suggest that gamma-ray bursts (GRBs) and their afterglows are produced by jets of highly relativistic cannonballs (CBs), emitted in supernova explosions. The fully ionized CBs cool to a temperature below 4500 K within a day or two, at which point electron-proton recombination produces an intense Lyman-$\alpha$ emission. …”

    “…Phosphorus is thought to be created by neutron capture on (29)Si and (30)Si in massive stars(20,21), and released into the interstellar medium by Type II supernova explosions(2,22). However, models of galactic chemical evolution must arbitrarily increase the supernovae production(23) to match observed abundances. …”

    “…Astrophysical data on the Supernova luminosity-distance - redshift relations, recalculated in terms of relative measurement standards, is utilized as a justification of conformal-invariant unified theory, where all masses, including masses of the Planck and Higgs, become the present- day values of dynamic variable of evolution of the universe in a regime of the dominances of a free scalar field. …”

    “…Explaining the XENON1T excess with transition magnetic moments is marginally possible if very conservative assumptions are adopted regarding the supernova 1987 A and CMB constraints. Finally, we discuss model-building challenges that arise in scenarios that feature large magnetic moments while keeping neutrino masses well below 1 eV. …”
