GW190425: Observation of a Compact Binary Coalescence with Total Mass ∼ 3.4 M O

B. P. Abbott, +1274 more
TL;DR: In 2019, the LIGO Livingston detector observed a compact binary coalescence with signal-to-noise ratio 12.9 and the Virgo detector was also taking data that did not contribute to detection due to a low SINR but were used for subsequent parameter estimation as discussed by the authors.

GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run

Richard J. Abbott, +1351 more
TL;DR: In this article, the authors present 39 candidate gravitational wave events from compact binary coalescences detected by Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between 1 April 2019 15:00 UTC and 1 October 2019 15.00.

Origin of the heaviest elements: The rapid neutron-capture process

TL;DR: In this article, the authors provide an answer to the question "How Were the Elements from Iron to Uranium Made?" (Abridged) by combining new results and important breakthroughs in the related nuclear, atomic and astronomical fields of science.
Journal ArticleDOI

Is there a supernova bound on axions

TL;DR: In this paper, the authors present a critical assessment of the SN1987A supernova cooling bound on axions and other light particles, showing that neutrinos do not cool the disk and do not affect its neutrino output.
Journal ArticleDOI

Core-collapse supernova explosion theory.

TL;DR: The delayed neutrino-heating mechanism is emerging as the key driver of supernova explosions, but there remain many issues to address, such as the chaos of the involved dynamics.

The Nucleosynthesis of 26Al and 60Fe in Solar Metallicity Stars Extending in Mass from 11 to 120 M☉: The Hydrostatic and Explosive Contributions

TL;DR: In this paper, the authors presented the 26Al and 60Fe yields produced by a generation of solar metallicity stars ranging in mass between 11 and 120 M☉, and quantified the relative contributions of various components.
Journal ArticleDOI

Observational Constraints on the Progenitors of Core-Collapse Supernovae: The Case for Missing High-Mass Stars

TL;DR: In this article, the authors show that the discovery rate of progenitor stars is limited by the local supernova rate and the availability and depth of archive images of galaxies, with 18 detections of precursor objects and 27 upper limits.
Journal ArticleDOI

Multidimensional supernova simulations with approximative neutrino transport. I. Neutron star kicks and the anisotropy of neutrino-driven explosions in two spatial dimensions

TL;DR: In this paper, the authors study hydrodynamic instabilities during the first seconds of core-collapse supernovae by means of 2D simulations with approximative neutrino transport and boundary conditions that parameterize the effects of the contracting neutron star.
Journal ArticleDOI

The nucleosynthesis of Al26 and Fe60 in solar metallicity stars extending in mass from 11 to 120 Msun: the hydrostatic and explosive contributions

TL;DR: In this article, the authors presented the yield of solar metallicity stars with mass between 11 and 120 µm and quantified the relative contributions of the various components of the solar wind, the C convective shell and the explosive Ne/C burning.
Journal ArticleDOI

TYPE Ib/c SUPERNOVAE IN BINARY SYSTEMS. I. EVOLUTION AND PROPERTIES OF THE PROGENITOR STARS

TL;DR: In this paper, the authors investigated the evolution of Type Ib/c supernova progenitors in close binary systems, using new evolutionary models that include the effects of rotation, with initial masses of 12-25 M ⌉ for the primary components, and of single helium stars with initial mass of 2.8-20 M ☉.
