Pulsational Pair-instability Supernovae [PDF]

open access: yes, 2016
The final evolution of stars in the mass range 70–140 M ⊙ is explored. Depending upon their mass loss history and rotation rates, these stars will end their lives as pulsational pair-instability supernovae (PPISN) producing a great variety of ...

Neutrino oscillations in supernovae: Angular moments and fast instabilities [PDF]

open access: yesPhysical Review D, 2019
Recent theoretical work indicates that the neutrino radiation in core-collapse supernovae may be susceptible to flavor instabilities that set in far behind the shock, grow extremely rapidly, and have the potential to profoundly affect supernova dynamics ...

Constraining High-energy Neutrino Emission from Supernovae with IceCube

open access: yesThe Astrophysical Journal Letters, 2023
Core-collapse supernovae are a promising potential high-energy neutrino source class. We test for correlation between seven years of IceCube neutrino data and a catalog containing more than 1000 core-collapse supernovae of types IIn and IIP and a sample ...

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

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

open access: yes, 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.

Cosmological Results from High-z Supernovae [PDF]

open access: yes, 2003
The High-z Supernova Search Team has discovered and observed eight new supernovae in the redshift interval z = 0.3-1.2. These independent observations, analyzed by similar but distinct methods, confirm the results of Riess and Perlmutter and coworkers ...

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”

Thermonuclear Supernovae [PDF]

open access: yesProceedings of Supernovae: lights in the darkness — PoS(SUPERNOVA), 2008
25 pages, 7 figures (some with reduced resolution), invited review at "Supernovae: lights in the darkness", October 3-5, 2007, Mao (Menorca), to appear in Proceedings of ...

Interstellar extinction from photometric surveys: application to four high-latitude areas

open access: yesOpen Astronomy, 2018
Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

Finding My Drumbeat: Applying Lessons Learned from Remo Ruffini to Understanding Astrophysical Transients

open access: yesUniverse, 2023
As with many fields from fashion to politics, science is susceptible to “bandwagon”-driven research where an idea becomes increasingly popular, garnering a growing amount of “scientific” support. Bandwagons allow scientists to converge on a solution, but
