Type Ia supernovae in globular clusters: observational upper limits [PDF]
, 2011 In the dense stellar environment of the globular clusters, compact binaries are produced dynamically. Therefore the fraction of type Ia supernovae that explode in globular clusters is expected to be higher than the fraction of mass residing in these.

On the Cosmological Transformation of Light: A Gravitational Analogue of the Photoelectric Effect
Reports in Advances of Physical Sciences, 2022 It is known that very distant galaxies, much like our own, show remarkably high receding velocities, the magnitude of which increases with distance.

Pulsational Pair-instability Supernovae [PDF]
, 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 ...

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 ...

Evolving Dark Energy or Supernovae Systematics? [PDF]
Monthly notices of the Royal Astronomical SocietyRecent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with ...

Collapsars: Gamma-Ray Bursts and Explosions in “Failed Supernovae” [PDF]
, 1998 Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα ≳ 10 M☉, in which iron-core collapse does not produce a successful outgoing shock but instead forms a black hole of 2-3 M☉. The model

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]
, 2014 X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

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

Lensing magnification of supernovae in the GOODS-fields [PDF]
, 2005 Gravitational lensing of high-redshift supernovae is potentially an important source of uncertainty when deriving cosmological parameters from the measured brightness of Type Ia supernovae, especially in deep surveys with scarce statistics.
