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.

Masses, Radii, and Equation of State of Neutron Stars

TL;DR: In this paper, the authors summarize the current knowledge of neutron star masses and radii and show that the neutron star mass distribution is much wider than previously thought, with 3 known pulsars now firmly in the 1.9-2.0 Msun mass range.
Journal ArticleDOI

Core-Collapse Supernovae from 9 to 120 Solar Masses Based on Neutrino-powered Explosions

TL;DR: In this paper, a grid of supernovae resulting from massive stars with solar metallicity and masses from 9.0 to 120 solar masses are calculated for nucleosynthesis, light curves, explosion energies, and remnant masses.
Journal ArticleDOI

Presupernova Evolution of Massive Single and Binary Stars

TL;DR: In this paper, the authors show that the main sequence stage offers the best opportunity to gauge the relevance of the various possible evolutionary scenarios, and sketching the post-main-sequence evolution of massive stars, for which observations of Wolf Rayet stars give essential clues.
Journal ArticleDOI

The Nuclear Equation of State and Neutron Star Masses

TL;DR: In this article, an ensemble of mass and radius observations can realistically restrict the properties of dense matter and, in particular, the behavior of the nuclear symmetry energy near the nuclear saturation density.
Journal ArticleDOI

Presupernova evolution of differentially rotating massive stars including magnetic fields

TL;DR: In this article, the authors present the first stellar evolution calculations to follow the evolution of rotating massive stars including, at least approximately, all these effects, magnetic and nonmagnetic, from the zero-age main sequence until the onset of iron-core collapse.
