UrduAn international team of astronomers have used a powerful array of radio telescopes to discover new insights about a magnetar that’s only a few hundred years old. By capturing precise measurements of the magnetar’s position and velocity, new clues emerge regarding its developmental path. When a relatively high-mass star collapses at the end of its life and explodes as a supernova, it can leave behind a superdense star called a neutron star.

El nacimiento de un monstruo magnético
Un equipo de investigadores, que incluía al astrónomo de NOIRLab André-Nicolas Chené, descubrió una inusual estrella con el campo magnético más poderoso jamás encontrado en una estrella masiva, que podría convertirla en uno de los objetos más magnéticos de todo el Universo, es decir, una variante de una estrella de neutrones conocida como “magnétar”. El hallazgo marca el descubrimiento de un nuevo tipo de objeto astronómico, una estrella de helio magnética masiva, y provee información sobre el origen de los magnétares.
Astronomers Shed New Light on Formation of Mysterious Fast Radio Bursts
International team reports on a radio pulsar phase of a Galactic magnetar that emitted a fast radio burst in 2020; observations suggest unique origins for “bursts” and “pulses,” which adds to FRB formation theory.
Astronomers Unveil New – and Puzzling – Features of Mysterious Fast Radio Bursts
More than 15 years after deep-space fast radio bursts were first discovered, their perplexing nature continues to surprise astronomers – and newly published research only deepens the mystery surrounding them.
Strange Radio Burst Raises New Questions
A highly active repeating Fast Radio Burst is raising new questions about the nature of such objects, and also raising doubts about their usefulness as cosmic yardsticks.
