Proceedings of 8th European VLBI Network Symposium — PoS(8thEVN), 2007 In this article I will briely review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio light curves of nearby core-collapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby ...

Entropy Generation Due to the Heat Transfer for Evolving Spherical Objects
Entropy, 2018 Heat transfer accompanying entropy generation for the evolving mini and microbubbles in solution is discussed based on the explicit solutions for the hydrodynamic equations related to the bubble motion. Even though the pressure difference between the gas

The Astrophysical Journal, 2023 Supernova neutrinos are invaluable signals that offer information about the interior of supernovae. Because a nearby supernova can occur at any time, preparing for future supernova neutrino observation is an urgent task.

QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO
Colloquium Exactarum, 2012 All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...

Significance of neutrino-neutrino interaction in neutrino oscillation in core-collapse supernova
Bibechana, 2014 We study the possibility of neutrino-neutrino interaction inside the neutrino core of supernova (ρ ≥ 1010 g/cc) and outside the neutrinosphere. The angular dependence of the neutrino-neutrino interaction Hamiltonian causes multi-angle effects that can ...

Fundamental physics studies in time domain and multi-messenger astronomy
Frontiers in Astronomy and Space SciencesThe era of ime domain and multi-messenger astronomy is not only leading to the development of a much broader set of detectors and instruments for astrophysical observations, but is also providing the means for astronomy to tie directly to cutting-edge ...

Limit on Supernova Emission in the Brightest Gamma-Ray Burst, GRB 221009A
The Astrophysical Journal Letters, 2023 We present photometric and spectroscopic observations of the extraordinary gamma-ray burst (GRB) 221009A in search of an associated supernova. Some past GRBs have shown bumps in the optical light curve that coincide with the emergence of supernova ...

How Tycho Brahe’s recordings in 1572 support SN 1572 as a type I(a) supernova
Frontiers in Astronomy and Space Sciences, 2023 The 450th anniversary of the discovery of the SN 1572 supernova event was celebrated in 2022. A closer look at the historical development of the field of supernova astronomy reveals the scientific importance of Tycho Brahe’s 1572 observations of this ...

Supernovae, by Chandra and XMM-Newton
UniverseX-ray emission from supernovae can arise from multiple interactions during their evolution. The immediate explosion is sufficiently energetic to generate X-rays; so, too, is the impact of the shock as it runs into circumstellar matter from earlier mass ...

Science, 2012 Stellar Explosions Stars that are born with masses greater than eight times that of the Sun end their lives in luminous explosions known as supernovae. Over the past decade, access to improved sky surveys has revealed rare types of supernovae that are much more luminous than any of those that were known before.
