Explosive Nucleosynthesis in Core-collapse Type II Supernovae: Insights from New C, N, Si, and Al–Mg Isotopic Compositions of Presolar Grains

The Astrophysical Journal Letters
We report C, N, Si, and Al–Mg isotope data for 39 presolar X silicon carbide (SiC) and four silicon nitride grains—a group of presolar grains that condensed in the remnants of core-collapse Type II supernovae (CCSNe)—isolated from the Murchison meteorite.

Type Ia Supernovae Can Arise from the Detonations of Both Stars in a Double Degenerate Binary

The Astrophysical Journal
The precise origin of Type Ia supernovae (SNe Ia) is unknown despite their value to numerous areas in astronomy. While it is a long-standing consensus that they arise from the explosion of a carbon/oxygen white dwarf, the exact progenitor configurations ...

The Impact of Recent LUNA Measurements of NeNa Reactions on ²⁶Al Stellar Nucleosynthesis

Universe
Recent measurements performed by the LUNA(Laboratory for Underground Nuclear Astrophysics) collaboration between 2019 and 2024 have provided the most precise direct determinations to date of several key reaction rates in the NeNa cycle, specifically the ...

A Photoionization Model for the Infrared Coronal Line Emission in the Classical Nova V1716 Scorpii

The Astrophysical Journal
A near-infrared spectrum of nova V1716 Scorpii (PNV J17224490-4137160), a recent bright ( ${V}_{\max }=7.3$ mag), Fermi-LAT detected γ -ray source, was modeled using the photoionization code CLOUDY.

Neutron Economy and Freeze-out Dynamics in the Late-time Cold r-process

The Astrophysical Journal
Standard r -process models often treat the freeze-out phase as a passive, uniform smoothing of the global abundance pattern. We demonstrate, however, that the final pattern is instead actively sculpted by a dynamic “neutron economy” that operates well ...

The chemical fingerprint of the Gaia BH3 system

Astronomy & Astrophysics
Context. The Gaia BH3 system hosts the most massive known stellar-origin black hole and a low-mass metal-poor companion whose chemical composition may help us constrain early explosive nucleosynthesis processes. Aims.
