Since it's rotating fast, I think it takes quite long to slow down to the extent that gravitational force outweights the centrifugal effect.Originally posted by physicskid
Since it bulges as it rotates, its angular momentum should decrease. So its rate of rotation would decrease too. But if its rotation slows down, its bulge would also decrease and its spin would increase again! So its rotation speed is irregular.
These stars, also known as "pulsars", emit beams of electromagnetic radiation that are highly regular and precise, leading scientists to believe that they may be signals from intelligent life forms. This has not been confirmed, however, and the exact mechanism behind these emissions is still not fully understood.
While most stars emit light and heat due to nuclear fusion reactions in their cores, pulsars emit radiation from their magnetic poles. They also rotate at incredibly high speeds, making them appear to "pulse" when observed from Earth.
Pulsars are found in various types of galaxies, including our own Milky Way. They are commonly found in binary systems, where they orbit around another star, but some are also found in isolation.
Yes, pulsars have been detected and studied for decades, using various instruments such as radio telescopes and X-ray detectors. However, the recent discovery of a repeating pattern in the signals from some pulsars has sparked renewed interest and research in this field.
Pulsars provide valuable insights into the physical processes and extreme conditions that exist in the universe. They also have practical applications, such as being used as a tool for navigation in space. Additionally, the possibility of these signals being evidence of extraterrestrial life raises profound questions about the existence of other intelligent beings in the universe.
