The recent discovery of the most massive neutron star near the black hole limit is an exciting development in the field of astronomy. The discovery of the most massive neutron star near the black hole limit is a significant development in understanding the physics of matter at extreme densities. The study, published in a peer-reviewed academic journal, aims to find more neutron stars pushing dangerously close to the black hole limit, further contributing to our understanding of black holes and neutron stars. Here are some reasons why this discovery is attractive:
Scientists discover the most massive neutron star
A recent study has discovered the most massive neutron star ever detected, PSR J0952–0607, located in the Sextans constellation between 3,200-5,700 light years away from Earth. The neutron star is about 2.35 times the mass of the Sun, close to the theoretical upper mass limit of around 2.3 solar masses for neutron stars. The previous record for the most massive neutron star was held by J0740+6620, which is about 2.14 times the mass of the Sun. This discovery highlights the potential of neutron stars and black holes in our universe.
Neutron stars, which are collapsed cores of massive stars between 8 and 30 times the mass of the Sun, are among the densest objects in the Universe. These cores, around 1.5 times the mass of the Sun, have a tipping point where the force of gravity overwhelms even the ability of neutrons to resist further collapse. Each “most massive” neutron star found brings us closer to identifying that tipping point and helping us understand the physics of matter at these mind-boggling densities. Black holes and neutron stars are the only objects denser than neutron stars.
Researchers conducted a study in The Astrophysical Journal Letters, focusing on neutron stars and black holes. The goal was to discover more neutron stars that are close to the black hole limit, potentially indicating that the limit has been reached. The study highlights the importance of neutron stars in understanding black hole dynamics.
Of neutron stars and pulsars
A neutron star is a type of extremely large star that is fueled by energy production in its cores. This process, involving nuclear fission, fuses lighter elements to form heavier ones, keeping the star hot and allowing gases to expand while drawing its mass towards the core in a delicate gravitational balance. Neutron stars, black neutron stars, and black holes are all examples of neutron stars.
A neutron star, a supermassive star between 10-25 solar masses, collapses due to the inability to produce enough energy for a supernova. The intense gravity and mass of the core cause it to collapse in on itself, resulting in a smaller, compact, and super dense stellar object. This is not to be confused with a white dwarf star, which is the result of the collapse of a much less massive star. Despite being hot, neutron stars need to cool down over a long period of time, but accretion and collisions can still grow them larger. Black holes and neutron stars are the result of the collapse of a much less massive star.
Neutron stars are a fascinating phenomenon that are not made up of normal atoms but rather formed entirely of neutrons due to the collapse of the star. These stars rotate incredibly quickly, sometimes hundreds of times per second, and can release beams of electromagnetic radiation when rotated. These pulsars, which emit jets of radiation, are the best way to spot neutron stars, as they otherwise don’t emit much radiation. There are believed to be several hundred million, if not a billion, of neutron stars in the Milky Way Galaxy alone. Black holes and neutron stars are also a part of the fascinating universe.
How massive is a neutron star?
Neutron stars, which are a fraction of their original star’s mass, measure between one to three solar masses. These compact stars, which are around 20 kilometers wide, are around the size of a city. The Tolman–Oppenheimer–Volkoff limit, a crucial astronomical concept, states that a neutron star must have a mass between one to three solar masses. However, the exact number is unclear, and other factors like the star’s spinning also play a role. Black holes and neutron stars are a result of the collision between the original star and the neutron star, forming a complex interplay of black holes and neutron stars.
Black holes are formed when neutrons condense and become more dense, potentially forming a neutron star. However, the formation of black holes and the existence of further stars like quark stars remains unclear. The most massive neutron star we know of is a black neutron star, which is a combination of black holes and neutron stars.

how do scientists measure the mass of a neutron star?
Scientists measure the mass of a neutron star using a variety of methods, including direct and indirect methods. Here are some ways scientists measure the mass of a neutron star:
scientists use a combination of direct and indirect methods to measure the mass of a neutron star. The most precise and reliable measurements of neutron star masses have been made for neutron stars that are in a binary system with another star. If a neutron star is by itself, scientists use indirect methods such as its brightness and temperature to estimate its mass. New work has found an interesting way to determine the mass of a type of neutron star known as a pulsar by detecting magnetic glitches.
what is the difference between a neutron star and a black hole?
Neutron stars and black holes are both fascinating objects in space, but they have some key differences. Here are some of the differences between neutron stars and black holes:
neutron stars and black holes are both fascinating objects in space, but they have some key differences. Neutron stars have a hard surface, while black holes do not. Neutron stars are formed when a massive star runs out of nuclear fuel and collapses under gravity, while black holes are formed when an extremely massive star dies in a supernova. The heaviest known neutron star has a mass equivalent to around 2.5 times the mass of the sun, while the lightest known black hole is about 5 solar masses.
what is the significance of discovering the most massive neutron star?
the discovery of the most massive neutron star is significant for advancing our understanding of the physics of neutron stars, challenging existing theories, advancing astrophysical observations, revealing more information about supernovas, and helping us understand the Universe.
what is a pulsar and how is it related to neutron stars?
a pulsar is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. Pulsars are a subset of the neutron star family, and they are observed to have pulses of radiation at very regular intervals. Pulsars have very strong magnetic fields which funnel jets of particles out along the two magnetic poles, producing very powerful beams of light. Pulsar timing is the regular monitoring of the rotation of the neutron star by tracking the arrival times of the radio pulses, and it has been used as a tool for scientific research.
how do scientists detect neutron stars?
Neutron stars, known for their peculiar characteristics, have been elusive to astronomers for years due to their unique characteristics. The most precise and reliable measurements of neutron star masses have been made for neutron stars in binary systems with another star. Neutron stars are detected through their electromagnetic radiation, and they can also be detected by their gravity affecting visible objects around them.
what is the name of the most massive neutron star discovered?
The most massive neutron star, J0740+6620, was discovered by astronomers using the Green Bank Telescope (GBT) approximately 4,600 light-years from Earth. This rapidly spinning pulsar is approaching the theoretical maximum mass possible for a neutron star, packing 2.17 times the mass of our Sun into a sphere only 30 kilometers across. The discovery challenges existing theories about the maximum mass of neutron stars and brings us closer to identifying the tipping point where the force of gravity overwhelms even the ability of neutrons to resist further collapse. Another neutron star, PSR J0952-0607, was discovered in 2022 and is even more massive than J0740+6620.
