SNe heating and the chemical evolution of the intra-cluster medium [PDF]

, 2002
We compute the chemical and thermal history of the intra-cluster medium in rich and poor clusters under the assumption that supernovae (I, II) are the major responsible both for the chemical enrichment and the heating of the intra-cluster gas.

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]

, 2014
X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

The Use of Multiwavelength Archival Observational Data for Scientific Discoveries: a Case of the Supernova Remnant Cassiopeia A

Open Astronomy, 2012
Most of the high-quality astronomical data after a proprietary period of typically one year are provided to open access, allowing researchers to complement their observations with the archival data in other wavelength bands, thus improving quality of the

Induced Gravitational Collapse, Binary-Driven Hypernovae, Long Gramma-ray Bursts and Their Connection with Short Gamma-ray Bursts

Universe, 2019
There is increasing observational evidence that short and long Gamma-ray bursts (GRBs) originate in different subclasses, each one with specific energy release, spectra, duration, etc, and all of them with binary progenitors.

Observational constraints on the progenitors of core-collapse supernovae : the case for missing high mass stars [PDF]

, 2015
Over the last 15 years, the supernova community has endeavoured to identify progenitor stars of core-collapse supernovae in high resolution archival images of their galaxies.This review compiles results (from 1999 - 2013) in a distance limited sample and

Weighing Cosmological Models with SNe Ia and Gamma Ray Burst Redshift Data

Universe, 2019
Many models have been proposed to explain the intergalactic redshift using different observational data and different criteria for the goodness-of-fit of a model to the data. The purpose of this paper is to examine several suggested models using the same

Mn abundances in the stars of the Galactic disc with metallicities -1.0 < [Fe/H] < 0.3 [PDF]

, 2015
In this work we present and discuss the observations of the Mn abundances for 247 FGK dwarfs, located in the Galactic disc with metallicity -1 < [Fe/H]< +0.3.

Impact of Newly Measured Nuclear Reaction Rates on ²⁶Al Ejected Yields from Massive Stars

Universe
Over the last three years, the rates of all the main nuclear reactions involving the destruction and production of 26Al in stars (26Al(n, p)26Mg, 26Al(n, α)23Na, 26Al(p, γ)27Si and 25Mg(p, γ)26Al) have been re-evaluated thanks to new high-precision ...

Anisotropic pressure effect on strongly magnetized white dwarfs using quasi-local equation of state

Journal of Scientific Research in Science, 2023
This work addresses the effect of anisotropic pressure on the strong magnetized white dwarf. A quasi-local equation of state is used to formulate the anisotropic factor inside the star. We use the assumption that the magnetic field is constant and strong

Spectropolarimetry of Supernovae

, 2008
Overwhelming evidence has accumulated in recent years that supernova explosions are intrinsically 3-dimensional phenomena with significant departures from spherical symmetry.
