Strong Progenitor Age Bias in Supernova Cosmology and Alignment with DESI BAO

Universe
Supernova (SN) cosmology is based on the assumption that the luminosity of type Ia SNe, after the luminosity standardization process, remains invariant with progenitor age.

Cosmic ray contributions from rapidly rotating stellar mass black holes: cosmic Ray GeV to EeV proton and anti-proton sources

Frontiers in Astronomy and Space Sciences
In Radio Super Novae (RSNe) a magnetic field of (B × r) = 1016.0±0.12 Gauss × cm is observed; these are the same numbers for Blue Super Giant (BSG) star explosions as for Red Super Giant (RSG) star explosions, despite their very different wind properties.

Physical mechanism of core-collapse supernovae that neutrinos drive

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences
The current understanding of the mechanism of core-collapse supernovae (CCSNe), one of the most energetic events in the universe associated with the death of massive stars and the main formation channel of compact objects such as neutron stars and black ...

The Evolution of Compact Binary Star Systems

Living Reviews in Relativity, 2006
We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the ...

Application of the Magnetar Engine to an Intermediate-Luminosity Gamma-Ray Burst Associated with the Supernova GRB 201015A/SN 201015A

Universe
We present optical photometry for the afterglow of GRB 201015A, which can be classified as a medium-luminosity gamma-ray burst (Lγ,iso≈2.55×1049ergs−1 ) and the associated underlying supernova SN 201015A.

The demographics of core-collapse supernovae

Astronomy & Astrophysics
Context. The observational properties of core-collapse supernovae are shaped by the envelopes of their progenitors. In massive binary systems, mass-transfer drastically alters the pre-supernova structures compared to single stars, which leads to a ...

Merger of Noncompact Binaries: Triggering Mechanisms and Merger Timescales of W UMa Contact Binaries

The Astrophysical Journal
The merger of noncompact binaries can produce a variety of significant celestial objects, including blue stragglers, luminous red novae, and others. However, several key details of the merger of noncompact binaries remain unclear.
