Neutron stars (pulsar or trumpet) are the remnants of stars at the end of their lives. 10-30 It is the result of the death of a sun-star. They are more massive than the Sun, although they are about 20 kilometers in diameter. This means that these objects are very dense.

The largest neutron star discovered is wetting his wife, who is constantly irradiated (Gabriel Pérez, SMM (IAC).).

Researchers at the Catalan Polytechnic University (UPC) and the Canary Islands Astrophysics Institute (IAC) have used a new method to measure the mass of one of the heaviest neutron stars ever discovered. The PSR J2215 + 5135, discovered in 2011, and about 2.3 solar masses, is one of the largest of more than 2,000 known neutron stars. The object calculated to be 2.4 solar masses in 2011 was considered to be 2 solar masses considering the studies in 2010 and 2013.

A new method was used in this study. The method gave more accurate results than those used to measure the mass of binary neutron stars. PSR is part of a dual star system in J2215 + 5135. His wife is a normal star like the Sun. This star is strongly irradiated by the neutron star.

The larger the neutron star, the faster it moves in its star orbital. In the new method, spectral hydrogen and magnesium lines were used to measure this movement. Looking at the portion of the star that does not receive the intense beam from the neutron star, it is determined that the neutron star has a mass greater than two times that of the Sun.

This method can also be applied to other neutron stars, which in the last 10 years have been discovered dozens of times similar to the Fermi-LAT NASA gamma-ray telescope. The method can also be applied to black hole and white dwarf in binary systems.

In addition to nuclear physics, astrophysics is also needed to determine the maximum mass of a neutron star. Interactions between nucleons (neutrons and protons in the atomic nucleus) at high densities are one of the questions that are being worked on to solve the present physics. The incredible intensity of the neutron stars constitutes a natural laboratory that we can observe.

The results of the study suggest that the pushing power between the neutron star’s particles in the nucleus must be strong enough to support the mass of the sun. This means that in the free state at the center of the neutron star there is no possibility of finding quarks and other extraordinary particles.
