The pulsar is estimated to have a mass of 1.4 M ☉, which is typical for most neutron stars and pulsars. The radius is estimated to be around 10 kilometres or 6.2 miles (~1.5 × 10 −5 R ☉), also common for pulsars and neutron stars. The pulsar is extremely hot, with a surface temperature of up to around 28,856 K (28,583 °C; 51,481 °F).

Density wave theory or the Lin–Shu density wave theory is a theory proposed by C.C. Lin and Frank Shu in the mid-1960s to explain the spiral arm structure of spiral galaxies. [ 1 ] [ 2 ] The Lin–Shu theory introduces the idea of long-lived quasistatic spiral structure (QSSS hypothesis). [ 1 ]
The pulsar was discovered in 2024 using the MeerKAT radio telescope. [63] M62H has a rotational period of 3.70 milliseconds, meaning it completes 270 rotations per second (270 Hz). [65] Its planetary companion has a minimum mass of 2.5 M J and a median mass of 2.83 M J, assuming a mass of 1.4 M ☉ for the pulsar. Its minimum density is of 11 g ...
This diagram shows the steps astronomers say are needed to create a pulsar with a superfast spin. 1. A massive supergiant star and a "normal" Sun-like star orbit each other. 2. The massive star explodes, leaving a pulsar that eventually slows down, turns off, and becomes a cooling neutron star. 3.
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]
The Black Widow Pulsar (PSR B1957+20) is an eclipsing binary millisecond pulsar in the Milky Way. Discovered in 1988, it is located roughly 6,500 light-years (2,000 parsecs) away from Earth . It orbits with a brown dwarf or Super-Jupiter companion with a period of 9.2 hours with an eclipse duration of approximately 20 minutes.
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."
