PSR J2032+4127, sometimes abbreviated as J2032, is a pulsar. It is accompanied by a massive Be star named MT91 213 (also 2MASS J20321312+4127243). The system is located in the constellation Cygnus at a distance of about 1.4 kpc (4,570 ly) from the Sun. The system is part of the Cygnus OB2 association.
It is expected that the coming together of the two stars in early 2018 will generate high-energy phenomena.[1]
The system has an orbital period of 46 years.[2] It completes rotation period of 0.1432 seconds and is characteristic age of 201,000 years old.
