DOI: 10.1007/s10509-017-3201-1
Abstract: In this paper, we first discuss a series of important but puzzling physical mechanisms concerning the energy source, various kinds of core collapsed supernovae explosion mechanisms during central gravitational collapse in astrophysics. We also discuss… read more here.

Dust in Supernovae and Supernova Remnants I: Formation Scenarios
Sign Up to like & getrecommendations! Published in 2018 at "Space Science Reviews"
DOI: 10.1007/s11214-018-0492-7
Abstract: Supernovae are considered as prime sources of dust in space. Observations of local supernovae over the past couple of decades have detected the presence of dust in supernova ejecta. The reddening of the high redshift… read more here.

DOI: 10.1016/j.dark.2019.100397
Abstract: In this work, we examine the possibility of using the diffuse supernova neutrino background (DSNB) to test the Chaplygin gas (CG) models of the Universe. With a typical supernova rate $R_{\mathrm{SN}}(z)$ and supernova neutrino spectrum… read more here.

DOI: 10.1017/pasa.2017.2
Abstract: Abstract We compare two Type Ia supernova samples that are drawn from a spectroscopically confirmed Type Ia supernova sample: a host-selected sample in which SNe Ia are restricted to those that have a spectroscopic redshift… read more here.

DOI: 10.1051/0004-6361/202037536
Abstract: Context: Tracing unstable isotopes produced in supernova nucleosynthesis provides a direct diagnostic of supernova explosion physics. Theoretical models predict an extensive variety of scenarios, which can be constrained through observations of the abundant isotopes $^{56}$Ni… read more here.

DOI: 10.1088/1475-7516/2023/04/027
Abstract: The origin of Galactic Cosmic Rays (CRs) and the possibility of Supernova Remnants (SNRs) being potential CR accelerators is still an open debate. The charged CRs can be detected indirectly by the γ-ray observatories through… read more here.

DOI: 10.1088/1674-4527/18/9/117
Abstract: Supernova remnant (SNR) G309.2-0.6 has a peculiar radio morphology with two bright ears to the southwest and northeast, although the main shell outside the ears is roughly circular. Based on an earlier proposal that the… read more here.

Abstract: In the far future long after star formation has ceased the universe will be populated by sparse degenerate remnants, mostly white dwarfs, though their ultimate fate is an open question. These white dwarfs will cool… read more here.

DOI: 10.1093/mnras/sty1053
Abstract: We find that the remnant of supernova (SN) 1987A share some morphological features with four supernova remnants (SNRs) that have signatures of shaping by jets, and from that we strengthen the claim that jets played… read more here.
