Researchers have recently found a new member of a rare class of stars in the Galaxy. According to Science Alert, the star is so rare that only a few have been found so far. It is called MAXI J1816-195 and is located no more than 30,000 light years away. Based on initial observations and research, astronomers believe that the extremely rare cosmic object is a pulsar of milliseconds with rising X-rays – a class of stars of which only 18 are known so far. It was first spotted on June 7 by the Monitor of All-sky Ray X-ray Image (MAXI) of the Japanese Space Agency located outside the International Space Station (ISS). Science Alert reports that a team led by astrophysicist Hitoshi Negoro of Nihon University in Japan explained that they had located an unclassified X-ray source at the galactic level between the constellations Sagittarius, Scutum and Serpens. They said it ignited relatively strongly, but they could not identify it based on MAXI data.

Using the space telescope, Neil Gehrels Swift Observatory astrophysicist Jamie Kennea of ​​Pennysylvania State University and colleagues visited the site to confirm the detection with an independent instrument and locate it. The telescope saw the object in X-rays, but not optical or ultraviolet light, at the position determined by the MAXI observations. The astronauts then used the Neutron Stellar Inner Synthesis Researcher (NICER) – a NASA X-ray instrument also mounted on the ISS. Interestingly, NICER picked up X-ray pulses at 528.6 Hz – indicating that the object rotates at a rate of 528.5 times per second – except for a thermonuclear X-ray burst. “This detection shows that MAXI J1816-195 is a neutron star and a new X-ray pulse that increases by a millisecond,” the astronauts said, according to Science Alert.

The researchers made observations using the Neil Gehrels Swift Observatory. The Liverpool Telescope on the Canary Island of La Palma in Spain has also been included for further observations.
