How does Angular Momentum relate to the rapid rotation of Pulsars?

AI Thread Summary
The discussion centers on the relationship between the Conservation of Angular Momentum and the rapid rotation of pulsars. It is noted that the angular momentum from the parent star is concentrated in the smaller pulsar, leading to increased rotation frequency. Additionally, some pulsars achieve even higher rotation rates due to momentum gained from infalling material, often from a companion star. The maximum observed rotation rate for pulsars is around 700 revolutions per second. This highlights the significant influence of angular momentum conservation in pulsar dynamics.

Hello,

Does the Conservation of Angular Momentum have any relation to the rapid rotation of Pulsars?
I've reasoned that the Angular Momentum of the "parent" star would be concentrated on the smaller pulsar and would produce a greater frequency of rotation.

Thanks,

You are basically correct, but some pulsars are even faster than that. The extra momentum comes from infalling material usually from a companion star. The max seems to be about 700 revolutions per second.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
