Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins
Journal of Big History, 2018 For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above ...

A Multidimensional Multicomponent Gas Dynamic with the Neutrino Transfer in Gravitational Collapse
Universe, 2022 The self-consistent problem of gravitational collapse is solved using 2D gas dynamics with taking into account the neutrino transfer in the flux-limited diffusion approximation.

The Carnegie Supernova Project: Absolute Calibration and the Hubble Constant [PDF]
Astrophysical Journal, 2018 We present an analysis of the final data release of the Carnegie Supernova Project I, focusing on the absolute calibration of the luminosity–decline rate relation for Type Ia supernovae (SNe Ia) using new intrinsic color relations with respect to the ...

Supernovae and cosmology [PDF]
New Astronomy Reviews, 2001 These lecture notes intend to form a short pedagogical introduction to the use of typical type Ia-Supernovae (hereafter SNIa) as standard candles to determine the energy density of the universe. Problems of principle for taking SNIa as cosmological probes are pointed out, and new attempts at solving them are indicated including the empirical width ...

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

Global comparison of core-collapse supernova simulations in spherical symmetry [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 We present a comparison between several simulation codes designed to study the core-collapse supernova mechanism. We pay close attention to controlling the initial conditions and input physics in order to ensure a meaningful and informative comparison ...

International 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.

Revisiting Supernova 1987A constraints on dark photons [PDF]
, 2016 A bstractWe revisit constraints on dark photons with masses below ∼ 100 MeV from the observations of Supernova 1987A. If dark photons are produced in sufficient quantity, they reduce the amount of energy emitted in the form of neutrinos, in conflict with
