Pulsars with compact companions in close eccentric orbits are unique laboratories for testing general relativity and alternative theories of gravity. Moreover, they are excellent targets for future gravitational wave experiments like LISA and they are also highly important for understanding the equation of state of super-dense matter and the evolution of massive binaries. Here we report on optical observations of the 1.02 M\(_{\odot }\) companion to the pulsar PSR J1141\(-\)6545. We detect an… Expand

THE BINARY COMPANION OF YOUNG, RELATIVISTIC PULSAR J1906+0746
PSR J1906+0746 is a young pulsar in the relativistic binary with the second-shortest known orbital period, of 3.98 hours. We here present a timing study based on five years of observations, conductedExpand
PSR J1755-2550: A young radio pulsar with a massive, compact companion
Radio pulsars found in binary systems with short orbital periods are usually fast spinning as a consequence of recycling via mass transfer from their companion stars; this process is also thought toExpand
A 1.05 M ☉ Companion to PSR J2222-0137: The Coolest Known White Dwarf?
The recycled pulsar PSR J2222–0137 is one of the closest known neutron stars (NSs) with a parallax distance of 267_(-0.9)^(+1.2) pc and an edge-on orbit. We measure the Shapiro delay in the systemExpand
Gravitational Radiation from Compact Binary Pulsars
An outstanding question in modern Physics is whether general relativity (GR) is a complete description of gravity among bodies at macroscopic scales. Currently, the best experiments supporting thisExpand
Gaia pulsars and where to find them
While the majority of massive stars have a stellar companion, most pulsars appear to be isolated. Taken at face value, this suggests that most massive binaries break apart due to strong natal kicksExpand
Einstein@Home discovery of a Double-Neutron Star Binary in the PALFA Survey
We report here the Einstein@Home discovery of PSR J1913+1102, a 27.3 ms pulsar found in data from the ongoing Arecibo PALFA pulsar survey. The pulsar is in a 4.95 hr double neutron star (DNS) systemExpand
Masses, Radii, and the Equation of State of Neutron Stars
We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing ofExpand
Lense–Thirring frame dragging induced by a fast-rotating white dwarf in a binary pulsar system
TLDR
Timing observations of PSR J1141-6545, a young pulsar in a binary orbit with a white dwarf, verify a prediction of general relativity and provide constraints on the evolutionary history of the binary system. Expand
The Role of Binary Pulsars in Testing Gravity Theories
Radio pulsars are neutron stars (NSs) which emit collimated beams of radio waves, observed as pulses, once per rotation of the NS. A subgroup of the radio pulsars behave as highly stable clocks andExpand
Testing Relativistic Gravity with Radio Pulsars
Before the 1970s, precision tests for gravity theories were constrained to the weak gravitational fields of the Solar system. Hence, only the weak-field slow-motion aspects of relativistic celestialExpand
