GRB-SN CONNECTION: CENTRAL ENGINE OF LONG GRBs AND EXPLOSIVE NUCLEOSYNTHESIS

, 2011
I have developed two-dimensional general relativistic magnetohydrodynamic (GRMHD) code. I have performed numerical simulations of collapsars using these codes and realistic progenitor models.

Reconciling the Tension between Light-curve Modeling of Type II Supernovae and Neutrino-driven Core-collapse Supernovae Models with Late-phase Spectroscopy

The Astrophysical Journal
Type II supernovae (SNe II) are the most frequently observed outcome of core-collapse explosions and provide a valuable window into the physical mechanisms governing the deaths of massive stars. However, estimates of explosion properties based on optical

Production of Heavy α-Elements and 44Ti in Cas A: Comparison to Abundances from 1D Core-collapse Supernova Models and Evidence for Carbon–Oxygen Shell Mergers

The Astrophysical Journal Letters
The merger between the carbon (C) and oxygen (O) shells hours to days before the collapse of a massive star significantly changes its nucleosynthesis, which is reflected in the elemental ratios observed in supernova remnants (SNRs).

Mapping 3D Explosive Nucleosynthesis in the Type II Supernova 2024ggi with Infrared Emission Lines

The Astrophysical Journal
We present analysis and modeling of optical and infrared (IR) spectroscopy of the type II supernova (SN II) 2024ggi obtained with ground-based instruments and the James Webb Space Telescope (JWST) at phases of ∼265–400 days.

Exploring the Neutrino Mass Hierarchy from Isotopic Ratios of Supernova Nucleosynthesis Products in Presolar Grains

The Astrophysical Journal
We study the nucleosynthesis in a core-collapse supernova (CCSN) model including newly calculated neutrino-induced reaction rates with both collective and Mikheyev–Smirnov–Wolfenstein neutrino flavor oscillations considered.

Type I X-Ray Burst Models with Rotation

The Astrophysical Journal
Type I X-ray bursts are powered by unstable thermonuclear burning on the surface of accreting neutron stars in close binary systems. These brief X-ray flashes, with light curves featuring rise times of 1–10 s, durations of 10–100 s, and recurrence ...

First Proton-Induced Cross Sections on a Stored Rare Ion Beam: Measurement of ${}^{118}\mathrm{Te}(\mathrm{p},\gamma )$ for Explosive Nucleosynthesis

International audienceWe present the first nuclear cross-section measurements of (p,γ) and (p,n) reactions on Te118 at energies relevant for the γ-process nucleosynthesis.
