Smoking supernovae [PDF]

open access: yesInternational Journal of Astrobiology, 2007
AbstractThe question ‘Are supernovae important sources of dust?’ is a contentious one. Observations with the Infrared Astronomical Satellite (IRAS) and the Infrared Space Observatory (ISO) only detected very small amounts of hot dust in supernova remnants.

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

open access: yesUniverse
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

open access: yesJournal 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

Physics with supernovae [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2002
Core-collapse supernovae (SNe) are powerful neutrino sources and as such important targets for the growing array of neutrino observatories. We review the current status of SN theory and the expected characteristics of the neutrino signal. After recalling what we have learned from SN 1987A and general SN properties we review the physics potential of a ...

Type Ia supernovae as speed sensors at intermediate redshifts [PDF]

open access: yes, 2008
Large scale peculiar velocity (LSPV) is a crucial probe of dark matter, dark energy, and gravity at cosmological scales. However, its application is severely limited by measurement obstacles. We show that fluctuations in type Ia supernovae fluxes induced

Evaluating machine learning models for supernova gravitational wave signal classification

open access: yesMachine Learning: Science and Technology
We investigate the potential of using gravitational wave (GW) signals from rotating core-collapse supernovae to probe the equation of state (EOS) of nuclear matter.

Estimation of Host Galaxy Extinction for SNe Ia

open access: yesGalaxies
Type Ia supernovae are used as fundamental probes of the cosmological parameters, based on a tight empirical relation between their peak luminosity and the width of their light curve. However, it has been recognized that SNe Ia are not “standard” candles,

A Review of the Theory of Galactic Winds Driven by Stellar Feedback

open access: yesGalaxies, 2018
Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals ...

Gap Transients Interacting with Circumstellar Medium

open access: yesUniverse, 2022
In the last 20 years, modern wide-field surveys discovered a new class of peculiar transients, which lie in the luminosity gap between standard supernovae and classical novae. These transients are often called “intermediate luminosity optical transients”
