SpaceTiger said:The neutron star's own gravity holds it together.
i think that a star spinning that fast would be very inplausible. we are talking of 38,500rpm, surely that's not likely to be correct?

-RA- said:what is the typical diameter of the rotating section of the pulsar?
SpaceTiger said:The paper you cite is not refuting the idea that pulsars are rotating -- there are no mainstream alternatives to the rotating pulsar model. The theoretical difficulty with pulsars is explaining the generation of their emission. That paper is attempting to distinguish between emission models.
Please be sure you fully understand something before trying to create a controversy. Many of your posts have been overly presumptuous in this regard.
-RA- said:Also there’s also some good data at http://www.mssl.ucl.ac.uk/~sz/Conference_files/pres/kuzmin.pdf , who also say that these very high energy bursts are likely caused by an recurring electrical discharge in the pulsars local environment.
A millisecond pulsar is a type of neutron star that rotates at incredibly high speeds, typically hundreds of times per second. They emit beams of radiation that can be detected on Earth, making them useful tools for studying the universe.
Millisecond pulsars are formed when a massive star reaches the end of its life and undergoes a supernova explosion, leaving behind a dense core made mostly of neutrons. As this core collapses, it spins up due to the conservation of angular momentum, resulting in a rapidly rotating pulsar.
Millisecond pulsars are unique because of their incredibly rapid rotation, which is caused by their small size and high density. They also have incredibly stable rotation periods, making them useful for precise timing measurements.
Scientists study millisecond pulsars by using radio telescopes to detect their radio emissions. By measuring the arrival times of the pulses, they can track the pulsar's rotation period and any changes in it over time. This can provide valuable information about the pulsar's properties and the space it resides in.
By studying millisecond pulsars, scientists can learn about a variety of topics, including the properties of neutron stars, the behavior of matter under extreme conditions, and the structure and evolution of our galaxy. They can also be used to test theories of gravity and general relativity.
