Investigadores miden el campo magnético en el medio del eclipse del púlsar araña PSR J2051-0827

Los púlsares araña son una subclase de sistemas binarios de púlsares de milisegundos con compañeros de baja masa en órbitas de período corto. En los púlsares araña, el viento del púlsar y la emisión electromagnética se ablan y pueden destruir a su compañero. Investigadores del Observatorio Astronómico de Xinjiang (XAO) de la Academia de Ciencias de China han medido el campo magnético del púlsar…

An article published in the journal 'Nature Astronomy' reports the detection of gamma-ray eclipses in binary systems formed by a normal star

An article published in the journal "Nature Astronomy" reports the detection of gamma-ray eclipses in binary systems formed by a normal star or a brown dwarf that have a pulsar as a companion that is defined as a spider pulsar because they steal gas from the companion behaving like a black widow. A team of researchers used data collected over a decade by NASA's Fermi Space Telescope to find cases in which the star passes in front of the pulsar. Seven binaries have been identified with a spider pulsar being eclipsed by its companion. This identification made it possible to measure the pulsar's mass, a result useful to conduct tests on the theory of relativity and understand the behavior of matter in extreme conditions.
