Mathematical simulation of vortex motion in the astrophysical objects on the basis of the gas-dynamic model [PDF]

Компьютерные исследования и моделирование, 2018
The application of a conservative numerical method of fluxes is examined for studying the vortex structures in the massive, fast-turned compact astrophysical objects, which are in self-gravity conditions.

Supernovae and transients with circumstellar interaction [PDF]

Royal Society Open Science, 2020
It is 30 years since the characteristic signatures of interaction with circumstellar material (CSM) were first observed in a core-collapse supernova. Since then, CSM interaction has been observed and inferred across a range of transients, from the low ...

Explosion Parameters of SN 2013df and Properties of Its Progenitor Star [PDF]

, 2014
Type IIb supernovae have only recently been identified as a distinct flavor of core-collapse stellar explosions. These supernovae represent a transitional type between Type II and Type Ib supernovae.

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

Open 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

High Energy Emission of Symbiotic Recurrent Novae: RS Oph and V407 Cyg

Open Astronomy, 2012
Recurrent novae occurring in symbiotic binaries are candidate sources of high energy photons, reaching GeV energies. Such emission is a consequence of particle acceleration leading to pion production.

Supernova Remnants and their Supernovae [PDF]

International Astronomical Union Colloquium, 1988
AbstractObserving supernova remnants provides important clues to the nature of supernova explosions. Conversely, the late stages of stellar evolution and the mechanism of supernova explosions affect supernova remnants through circumstellar matter, stellar remnants, and nucleosynthesis. The elements of supernova classification and the connection between

Topics in Core-Collapse Supernova Theory: The Formation of Black Holes and the Transport of Neutrinos [PDF]

, 2012
Core-Collapse Supernovae are one of the most complex astrophysical systems in the universe. They deeply entwine aspects of physics and astrophysics that are rarely side by side in nature.

The Hubble Diagram: Jump from Supernovae to Gamma-ray Bursts

Universe, 2022
The Hubble diagram (HD) is a plot that contains a luminous distance modulus presented with respect to the redshift. The distance modulus–redshift relation of the most well-known “standard candles”, the type Ia supernovae (SN), is a crucial tool in ...

A statistical analysis of circumstellar material in Type Ia supernovae [PDF]

, 2013
A key tracer of the elusive progenitor systems of Type Ia supernovae (SNe Ia) is the detection of narrow blueshifted time-varying Na I D absorption lines, interpreted as evidence of circumstellar material surrounding the progenitor system.
