    Scientists have found the heaviest neutron star in the universe: that's not all of its features

    This unusual black widow pulsar is also the second fastest rotating neutron star in our galaxy.

    Scientists from Stanford University, USA, have found that a unique neutron star is the most massive of its kind in the observable universe. It is not only the heaviest, but also the second fastest pulsar in the Milky Way, which “feeds” on the matter of its companion star, according to ScienceAlert.

    The pulsar PSR J0952-0607 is one of the most interesting for science neutron stars in our galaxy. It rotates at an incredible speed and is the second fastest in the Milky Way. Its speed is 707 revolutions around its axis per second. The fastest pulsar rotates at a speed of 716 revolutions.

    This star is called the “black widow”, as it is very close to another star and due to this “sucks” the stellar matter from its companion. Due to this, an accretion disk is formed around the neutron star, which also affects the increase in the speed of rotation of the pulsar.

    Through careful study of this binary star system, American scientists have determined that PSR J0952-0607 is the most massive neutron star in the known universe. It is believed that the standard mass of such a neutron star is about 1.4 times the mass of the Sun and its maximum mass can reach 2.3 times the mass of our star.

    But the pulsar companion has a mass that is only 10% of the mass of the Sun, which means that the neutron star has taken almost all the matter of its neighbor and it may soon disappear altogether. It is the huge amount of absorbed matter that led to the fact that the pulsar PSR J0952-0607 has a mass that exceeds the mass of the Sun by 2.35 times. And this is the largest figure among all discovered neutron stars.

    Neutron stars appear after a star, which had a mass of about 8 to 30 solar masses, exploded in a supernova and did not turn into a black hole. These are practically the densest objects in the Universe, only black holes are denser than them.

    Basically, neutron stars are a sphere with a diameter of about 20 km. Pulsars are a type of neutron stars that seem to pulsate at certain periods of time and release jets of radiation into space. But until now, scientists still have too little information about the processes that occur in neutron stars.

    Focus has already written in detail about such star systems and the fact that scientists managed to detect the densest of them.

    As for other space exploration, scientists using the Webb telescope focused their attention on the TRAPPIST-1 planetary system. This star system hosts several rocky exoplanets that are Earth-like and could harbor life.
