Arecibo Pulsar Survey Using ALFA. II. The Young, Highly Relativistic Binary Pulsar J1906+0746
We report the discovery of PSR J1906+0746, a young 144 ms pulsar in a highly relativistic 3.98 hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence time of 300 Myr. The new pulsar was found during precursor survey observations with the Arecibo 1.4 GHz feed array system and retrospectively detected in the Parkes Multibeam plane pulsar survey data. From radio follow-...
متن کاملBounding the mass of the graviton using binary pulsar observations
The close agreement between the predictions of dynamical general relativity for the radiated power of a compact binary system and the observed orbital decay of the binary pulsars PSR B1913+16 and PSR B1534+12 allows us to bound the graviton mass to be less than 7.6× 10−20 eV with 90% confidence. This bound is the first to be obtained from dynamic, as opposed to staticfield, relativity. The resu...
متن کاملBounding the graviton mass with binary pulsar observations
By comparing the observed orbital decay of the binary pulsars PSR B1913+16 and PSR B1534+12 to that predicted by general relativity due to gravitational-wave emission, we are able to bound the mass of the graviton to be less than 7.6 × 10−20 eV/c2 at 90% confidence. This is the first such bound to be derived from dynamic gravitational fields. It is approximately two orders of magnitude weaker t...
متن کاملOptical Detection of Two Intermediate Mass Binary Pulsar Companions
We report the detection of probable optical counterparts for two Intermediate Mass Binary Pulsar (IMBP) systems, PSR J1528−3146 and PSR J1757−5322. Recent radio pulsar surveys have uncovered a handful of these systems with putative massive white dwarf companions, thought to have an evolutionary history different from that of the more numerous class of Low Mass Binary Pulsars (LMBPs) with He whi...
متن کاملDiscovery of an X–ray Pulsar in the Low–mass X-ray Binary 2a 1822–371
We report the discovery of 0.59 s X–ray pulsations from the low–mass X–ray binary, 5.57 hr dipping and eclipsing ADC source 2A 1822–371. Pulse arrival time analysis indicates a circular orbit with e <0.03 (95% confidence) and an asini for the neutron star of 1.006(5) lightseconds, implying a mass function of (2.03± 0.03)× 10M⊙. The barycentric pulse period was 0.59325(2) s in 1996.270 and 0.593...
