Rapid identification of lensed type Ia supernovae with color-magnitude selection

The Open Journal of Astrophysics
Strongly lensed type Ia supernovae (SNe Ia) provide a unique cosmological probe to address the Hubble tension problem in cosmology. In addition to the sensitivity of the time delays to the value of the Hubble constant, the transient and standard candle ...

Probing Supernova Diversity Through High-Cadence Optical Observations

Universe
Supernovae (SNe) are among the most energetic and transient events in the universe, offering crucial insights into stellar evolution, nucleosynthesis, and cosmic expansion.

Metallicity effects on cosmic Type Ib/c supernovae and gamma-ray burst rates [PDF]

, 2017
Type Ib/c supernovae (SNe Ib/c) are likely to be associated with long gamma-ray bursts (GRBs), and therefore it is important to compare the SN rate in galaxies with the GRB rate. To do this we computed SN Ib/c rates in galaxies of different morphological

A Multiwavelength View of the Nearby Calcium-strong Transient SN 2025coe in the X-Ray, Near-infrared, and Radio Wavebands

The Astrophysical Journal
Calcium-strong transients (CaSTs) are a subclass of faint and rapidly evolving supernovae (SNe) that exhibit strong calcium features and notably weak oxygen features.

Visual Orbits of Wolf–Rayet Stars. II. The Orbit of the Nitrogen-rich Wolf–Rayet Binary WR 138 Measured with the CHARA Array

The Astrophysical Journal
Classical Wolf–Rayet (WR) stars are descendants of massive OB-type stars that have lost their hydrogen-rich envelopes and are in the final stages of stellar evolution, possibly exploding as Type Ib/c supernovae.

A Systematic Search for Rapid Transients in the Subaru HSC-SSP Transient Survey

The Astrophysical Journal
Recent high-cadence transient surveys have discovered rapid transients whose light-curve timescales are shorter than those of typical supernovae (SNe). In this paper, we present a systematic search for rapid transients at medium-high redshifts among 3381

Nucleosynthesis in supernovae

, 2002
The evolution of gas abundances in galaxies and the enrichment of heavy elements as a function of space and time reflects the history of star formation and the lifetimes of the diverse contributing stellar objects. Supernovae of type la and type II/Ib/Ic

Can circumstellar interaction explain the strange light-curve features of Type Ib/c supernovae?

Context. The evolution and surrounding of the progenitors of stripped-envelope supernovae are still debated: some studies suggest single-star progenitors, but others prefer massive binary progenitors.
