The astronomers of NASA have discovered a record-breaking star system which is known as IGR J17062-6143. It is a very compact binary system as one of the stars is spinning at great speed and this neutron star is called an X-ray pulsar.
The data of NICER shows that the two orbits of the star move in every 38 minutes and they are separated by about 186,000 miles which is less than the distance of the Moon from the Earth. J17062 was observed NICER for over seven hours and about 5.3 days and from this observation t is confirmed that it is orbiting at a record-breaking speed.
According to the Tod Strohmayer, who is an astrophysicist at NASA’s Goddard Space Flight Center and also the lead author of the paper on this subject, said “It’s not possible for a hydrogen-rich star, like our Sun, to be the pulsar’s companion. You can’t fit a star like that into an orbit so small.”
The study of this done by the NASA Neutron Star Interior Composition Explorer (NICER). It is an X-ray detection instrument which is installed in the ISS in June 2017. The old research which was done on this during the year 2008 shows for about 20-minute observation shows that J17062 X-ray pulses have occurred 163 times every second. This means that the pulsar was rotating at its axis which is almost 10,000 times every minute. The two stars create the orbits around each other in such a way that this case is accreting millisecond X-ray pulsars (AMXP).
This study was published online on Wednesday in the Astrophysical Journal Letters under the “NICER Discovers the Ultracompact Orbit of the Accreting Millisecond Pulsar IGR J17062-6143.” The main objective of the NISER was to study the physics and behaviour of the neutron.
