Neutron stars and their properties
Neutron stars are fascinating celestial objects formed from the remnants of supernova explosions. They are incredibly dense and have a strong gravitational pull that crushes their protons and electrons, leaving only neutrons in their nuclei. These stars are incredibly small, with a diameter of about 20 kilometers or less, but have masses 1.4 to 2 times that of the sun. Despite their size, neutron stars are incredibly powerful and have unique properties that make them stand out from other celestial objects.
Properties of neutron stars
- Strong magnetic fields: Neutron stars have incredibly strong magnetic fields, which are a million times stronger than those on Earth. These fields produce intense radiation that can be observed by astronomers as X-rays, radio waves, and gamma rays.
- Fast rotation: Neutron stars rotate incredibly fast; some complete one rotation every few milliseconds. This fast rotation is due to the conservation of angular momentum during the supernova explosion that formed the star. Some neutron stars can spin at over 700 revolutions per second!
- Gravitational force: Neutron stars have an incredibly strong gravitational force that can bend light, similar to black holes. However, unlike black holes, neutron stars have a solid surface, and anything that falls onto it will collide with the surface and produce intense radiation.
The fastest rotating neutron star
The fastest rotating neutron star, also known as a pulsar, was discovered in 2016 by researchers using the Green Bank Telescope in West Virginia. The star, named PSR J1748-2446ad, rotates at an incredible speed of 43,000 revolutions per minute, making it the fastest rotating neutron star ever discovered.
| Property | Value |
|---|---|
| Diameter | 20 km or less |
| Mass | 1.4 – 2 times the mass of the sun |
| Magnetic fields | A million times stronger than those on Earth |
| Rotation speed | Up to 700 revolutions per second |
Neutron stars are fascinating objects that continue to fascinate researchers and astronomers. Their unique properties and behaviors offer insight into the physical laws that govern the universe. The discovery of PSR J1748-2446ad, the fastest rotating neutron star, is a testament to the incredible diversity of celestial objects that exist in our universe.
Understanding the mechanism behind neutron stars’ fast rotation
Neutron stars are fascinating astronomical objects that have captured the attention of scientists for decades. The fastest rotating neutron star is named PSR J1748-244, which rotates about 43,000 times per minute or 24% the speed of light. But what is the mechanism that allows neutron stars to spin so rapidly?
- Conservation of angular momentum: Neutron stars are formed when a massive star undergoes a supernova explosion at the end of its life. During the explosion, the outer layers of the star are ejected into space while the core collapses due to the strong gravitational force. The conservation of angular momentum is what causes the neutron star to spin so rapidly. Like a figure skater who spins faster when they pull their arms closer to their body, as the core collapses, it spins faster and faster.
- Neutron star surface features: Neutron stars have strong magnetic fields that cause them to emit radiation as they rotate. The radiation can be seen as pulsations, which is why neutron stars are also known as pulsars. Scientists study the radiation emitted by neutron stars to determine their rotation speed.
- Accretion disks: Some neutron stars are in binary systems, meaning they orbit around another star. As the neutron star orbits, it can pull matter from its companion star, forming an accretion disk around the neutron star. The matter in the disk can spin the neutron star faster, just like a figure skater who spins faster when they pull their arms closer to their body.
Understanding the mechanism behind neutron stars’ fast rotation is crucial to learning more about these astronomical objects. Scientists continue to study neutron stars to better understand their behavior and unlock the secrets of the universe.
Researchers have been studying neutron stars for decades, and they continue to uncover new information about these fascinating cosmic objects.

How do neutron stars form?
Neutron stars are some of the most awe-inspiring celestial objects in the universe. They are formed from the remnants of supernova explosions, which occur at the end of a massive star’s life. When a massive star runs out of nuclear fuel, its core collapses inward due to gravity. The collapse causes the core’s materials to reach an incredibly high density, forming a neutron star.
- During the collapse, protons and electrons are squeezed together to form neutrons, hence the name “neutron star.”
- These stars are incredibly compact, with a mass greater than that of the sun but a radius only about 10 kilometers.
- They also have extremely strong magnetic fields, which can cause them to emit beams of radiation that can be detected on Earth. These beams of radiation create the pulsating effect that gives pulsars their name.
Neutron stars rotate incredibly fast due to the conservation of angular momentum during the collapse. The more massive the original star, the faster the neutron star will rotate. The fastest rotating neutron star discovered so far is the pulsar PSR J1748-2446ad, which spins at a mind-boggling rate of 716 times per second!
Scientists continue to study neutron stars to gain a better understanding of the fundamental principles of physics and the behavior of matter under extreme conditions.

| Mass | 1.4-2.1 solar masses |
| Radius | 10-15 km |
| Density | 1017-1018 kg/m3 |
| Magnetic Field | 108-1015 gauss |
| Rotation Period | Milliseconds to several seconds |
Neutron stars are fascinating objects that challenge our understanding of the universe. By studying them, we can gain insights into the fundamental principles of physics and the behavior of matter under extreme conditions.
Pulsars: the highly magnetized, rotating neutron star
Pulsars are one of the most fascinating objects in the universe. They are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles. These beams of radiation can be detected from Earth as pulsing radio waves.
- Pulsars are formed when a massive star explodes in a supernova and its core collapses into a highly dense and compact object, a neutron star.
- Pulsars have incredibly strong magnetic fields, billions of times stronger than the Earth’s magnetic field.
- Pulsars rotate rapidly, with some spinning hundreds of times per second.
The fastest rotating pulsar ever discovered is the PSR J1748-2446ad, located in the globular cluster Terzan 5, about 28,000 light-years from Earth. This pulsar rotates at an incredible speed of 716 times per second!

Comparison of Neutron Stars with Other Astronomical Objects
Neutron stars are one of the most fascinating objects in the universe. They are the collapsed cores of massive stars that have gone supernova, leaving behind incredibly dense and massive bodies that can rotate hundreds of times per second.
- Compared to the sun, neutron stars are incredibly small. They typically have a radius of only about 10 kilometers, which is roughly the size of a medium-sized city!
- However, despite their small size, neutron stars are incredibly massive. In fact, they are so dense that a teaspoonful of neutron star material would weigh about as much as Mount Everest!
- Moreover, neutron stars are some of the fastest rotating objects in the universe. The fastest known neutron star is the pulsar known as PSR J1748-2446ad, which rotates at a rate of 716 times per second!
Despite their unique characteristics, neutron stars share some similarities with other astronomical objects. For example:
- Black holes: Like neutron stars, black holes are incredibly dense objects that result from the collapse of massive stars. However, whereas neutron stars have a hard surface, black holes are defined by the event horizon – the point of no return beyond which the gravitational pull is too strong even for light to escape.
- White dwarfs: White dwarfs are also the remnants of old stars, but they are less massive than neutron stars and don’t rotate as fast. Unlike neutron stars, white dwarfs can cool down and eventually become “dead” objects that no longer produce heat or light.
- Planets: At first glance, comparing a neutron star to a planet seems like comparing apples and oranges. However, both show evidence of strong magnetic fields and are thought to have a layered, differentiated structure – with an outer crust, a mantle, and a core.
Overall, neutron stars are some of the most unique and fascinating objects in the universe. No other object comes close to their incredible density, extreme rotation speeds, and intense magnetic fields.
