How Massive Single Stars End Their Life
- A. Heger, Chris L. Fryer, S. Woosley, N. Langer, D. Hartmann

How massive stars die—what sort of explosion and remnant each produces—depends chiefly on the masses of their helium cores and hydrogen envelopes at death. For single stars, stellar winds are the…
THE NUCLEAR SPECTROSCOPIC TELESCOPE ARRAY (NuSTAR) HIGH-ENERGY X-RAY MISSION
- F. Harrison, W. Craig, C. M. Urry
- PhysicsIEEE Aerospace Conference
- 30 January 2013
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 2012 June 13, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3 to 79 keV,…
Hyperaccreting Black Holes and Gamma-Ray Bursts
- R. Popham, S. Woosley, Chris L. Fryer
- Physics
- 2 July 1998
A variety of current models of gamma-ray bursts (GRBs) suggest a common engine: a black hole of several solar masses accreting matter from a disk at a rate of 0.01 to 10 M☉ s-1. Using a numerical…
ON THE MAXIMUM MASS OF STELLAR BLACK HOLES
- K. Belczynski, T. Bulik, J. Hurley
- Physics
- 17 April 2009
We present the spectrum of compact object masses: neutron stars and black holes (BHs) that originate from single stars in different environments. In particular, we calculate the dependence of maximum…
The X-ray counterpart to the gravitational-wave event GW170817
The detection of X-ray emission at a location coincident with the kilonova transient provides the missing observational link between short γ-ray bursts and gravitational waves from neutron-star mergers, and gives independent confirmation of the collimated nature of the γ,ray-burst emission.
Multi-messenger Observations of a Binary Neutron Star Merger

- 26 October 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced…
A New Look at the Binary Characteristics of Massive Stars
- H. Kobulnicky, Chris L. Fryer, University of Wyoming, Los Alamos National Laboratory
- Physics
- 2 May 2006
We constrain the properties of massive binaries by comparing radial velocity data on early-type stars in Cygnus OB2 with the expectations of Monte Carlo models. Our comparisons test several popular…
Formation Rates of Black Hole Accretion Disk Gamma-Ray Bursts
- Chris L. Fryer, S. Woosley, D. Hartmann
- PhysicsAstrophysical Journal
- 9 April 1999
The cosmological origin of at least an appreciable fraction of classical gamma-ray bursts (GRBs) is now supported by redshift measurements for a half-dozen faint host galaxies. Still, the nature of…
A gravitational-wave standard siren measurement of the Hubble constant
- B. Abbott, R. Abbott, M. Serra-Ricart
- PhysicsNature
- 16 October 2017
A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data.
Theoretical Black Hole Mass Distributions
- Chris L. Fryer, V. Kalogera
- Physics
- 16 November 1999
We derive the theoretical distribution function of black hole masses by studying the formation processes of black holes. We use the results of recent two-dimensional simulations of stellar core…
