The system consists of one tiny planet with a mass of 0.02 ± 0.002 Earth masses and two Super-Earths with masses 4.3 ± 0.2 and 3.9 ± 0.2 times that of Earth, assuming that the pulsar has a mass of 1.4 solar masses. [70] They most likely formed from a protoplanetary disk, [1] probably generated from the partial destruction of a companion star ...
Neutron stars, including pulsars, can be as small as about 12 miles across—if Earth rotated at the same speed as one of these stars, an Earth day would be nearly 4,300 hours long.
An intermediate-mass binary pulsar (IMBP) is a pulsar-white dwarf binary system with a relatively long spin period of around 10–200 ms consisting of a white dwarf with a relatively high mass of approximately . [7] The spin periods, magnetic field strengths, and orbital eccentricities of IMBPs are significantly larger than those of low mass binary pulsars (LMBPs). [7]
PSR B1919+21 is a pulsar with a period of 1.3373 seconds [4] and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell on 28 November 1967, it is the first discovered radio pulsar. [5]
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.
One of only two pulsars known to have stopped pulsing for more than a few minutes. PSR B1931+24, has a cycle. It pulses for about a week and stops pulsing for about a month. [71] One of only two pulsars known to have stopped pulsing for more than a few minutes. Swift J0243.6+6124 most magnetic pulsar with 1.6 × 10 13 G. [72] [73]
The system was originally observed by an international team during a high-latitude multibeam survey organized in order to discover more pulsars in the night sky. [2] Initially, this star system was thought to be an ordinary pulsar detection. The first detection showed one pulsar with a period of 23 milliseconds in orbit around a neutron star.
PSR J0002+6216, also dubbed the Cannonball Pulsar, is a pulsar discovered by the Einstein@Home project in 2017. [2] It is one of the fastest moving pulsars known, and has moved 53 ly (5.0 × 10 14 km; 3.1 × 10 14 mi) away from the location of its formation supernova, where the remaining supernova nebula, CTB 1 (Abell 85 [3]), is.
