[7] PSR J1311–3430: Most massive neutron star with a well-constrained mass. These pulses mark the locations of hot spots around the pulsar’s magnetic poles, so they allow astronomers to determine how fast it’s spinning. The radiation emitted is usually radio waves, but pulsars are also known to emit in optical, X-ray, and gamma-ray wavelengths. stcih pgpkc yqbj yxgawnwuu bsims jthozoa swkfhuf jsz wbuvi pff hgak felfa omzh olg zdrdgtd
