Journal ArticleDOI
A two-solar-mass neutron star measured using Shapiro delay
Paul Demorest,Timothy T. Pennucci,Scott M. Ransom,Mallory S. E. Roberts,Jason W. T. Hessels,Jason W. T. Hessels +5 more
TL;DR: Radio timing observations of the binary millisecond pulsar J1614-2230 that show a strong Shapiro delay signature are presented and the pulsar mass is calculated to be (1.97 ± 0.04)M⊙, which rules out almost all currently proposed hyperon or boson condensate equations of state.
Journal ArticleDOI

W. Verbiest,David G. Whelan +25 more
TL;DR: Pulsar J0348+0432 is only the second neutron star with a precisely determined mass of 2 M☉
Journal ArticleDOI

Pennucci,Renée Spiewak,Ingrid H. Stairs,Kevin Stovall,Joseph K. Swiggum,Weiwei Zhu +28 more
TL;DR: In this article, the authors measured the mass of the MSP J0740+6620 to be ${\mathbf{2.14} + 2.09} + 0.10% credibility interval.
Journal ArticleDOI
Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar
H. Thankful Cromartie,Emmanuel Fonseca,Scott M. Ransom,Paul Demorest,Zaven Arzoumanian,Harsha Blumer,Paul R. Brook,Megan E. DeCesar,Timothy Dolch,Justin A. Ellis,Robert D. Ferdman,Elizabeth C. Ferrara,N. Garver-Daniels,P. A. Gentile,Megan L. Jones,Michael T. Lam,Duncan R. Lorimer,Ryan S. Lynch,Maura McLaughlin,Cherry Ng,David J. Nice,Timothy T. Pennucci,Renée Spiewak,Ingrid H. Stairs,Kevin Stovall,Joseph K. Swiggum,Weiwei Zhu +26 more
TL;DR: In this article, the relativistic Shapiro delay (Shapiro 1964) was used to estimate the masses of a pulsar binary system, and the mass of the binary system was found to be 2.14+0.10−0.18−1.

TL;DR: In this article, the authors presented high-precision timing data over time spans of up to 11 years for 45 millisecond pulsars observed as part of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) project, aimed at detecting and characterizing low-frequency gravitational waves.
