An ultra-rare space object found in the Milky Way

The object was named MAXI J1816-195, it is located at a distance of no more than 30,000 light years from Earth. Preliminary

observations and studies indicate that it is an accreting millisecond X-ray pulsar. According to the pulsar database, there are only 18 of them. 

X-ray light emanating from the object was first recorded on June 7 using the Monitor of All-sky X-ray Image (MAXI) device.

Using the Neil Gehrels Swift Observatory space telescope, astrophysicist Jamie Kenny of Pennsylvania State University and colleagues located the object.

The NICER X-ray device recordedX-ray pulsations with a frequency of 528.6 Hz - he suggested that the object rotates at a speed of 528.6 times per second. Also  NICER detects thermonuclear X-ray burst. This was due to the unstable thermonuclear burning of material that the companion star had accumulated.

As a result, the team found that MAXI J1816-195 is a neutron star and an accreting millisecond X-ray pulsar.
