PSR J0737−3039 is the first known double pulsar.It consists of two neutron stars emitting electromagnetic waves in the radio wavelength in a relativistic binary system.The two pulsars are known as PSR J0737−3039A and PSR J0737−3039B.
The digital display on received newer graphics and a Blue back light instead of the previously Orange back light. The Pulsar 150 received mechanical changes to conform to BS4 norms, leading to a loss of 1 Ps of power. The Pulsar 180 received a 230mm rear disc brake instead of a drum brake. A new model named the Pulsar NS160 was released soon after.
In 1982, Don Backer led a group that discovered PSR B1937+21, a pulsar with a rotation period of just 1.6 milliseconds (38,500 rpm). [28] Observations soon revealed that its magnetic field was much weaker than ordinary pulsars, while further discoveries cemented the idea that a new class of object, the "millisecond pulsars" (MSPs
Pulsar XP (also called the XP912) Improved model, with higher gross weight, powered by an 80 hp (60 kW) Rotax 912UL four-stroke powerplant and introduced in 1992 by Aero Designs. [2] Pulsar Series II Improved model, powered by a 100 hp (75 kW) Rotax 912ULS four-stroke or 115 hp (86 kW) Rotax 914 turbocharged powerplant and produced by SkyStar ...
PSR J0952–0607 is a massive millisecond pulsar in a binary system, located between 3,200–5,700 light-years (970–1,740 pc) from Earth in the constellation Sextans. [6] It holds the record for being the most massive neutron star known as of 2022, with a mass 2.35 ± 0.17 times that of the Sun—potentially close to the Tolman–Oppenheimer–Volkoff mass upper limit for neutron stars.
[1] In 2013, a slightly higher neutron star mass measurement was announced for PSR J0348+0432, 2.01 ± 0.04 M ☉. [5] This confirmed the existence of such massive neutron stars using a different measuring technique. After further high-precision timing of the pulsar, the mass measurement for J1614–2230 was updated to 1.908 ± 0.016 M ☉ in ...
PSR J1719−1438 b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719−1438, a millisecond pulsar. The pulsar planet is most likely composed largely of crystalline carbon but with a density far greater than diamond. [1] [2] PSR J1719-1438 b orbits so closely to its host star that its orbit would fit ...
The pulsar was discovered by Russell Alan Hulse and Joseph Hooton Taylor Jr., of the University of Massachusetts Amherst in 1974. Their discovery of the system and analysis of it earned them the 1993 Nobel Prize in Physics "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation."
