magnetar Definition and 1 Threads
A magnetar is a type of neutron star with an extremely powerful magnetic field (~109 to 1011 T, ~1013 to 1015 G). The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays.
The existence of magnetars was proposed in 1992 by Robert Duncan and Christopher Thompson. Their proposal sought to explain the properties of transient sources of gamma rays, now known as soft gamma repeaters (SGRs). Over the following decade, the magnetar hypothesis became widely accepted, and was extended to explain anomalous X-ray pulsars (AXPs). As of July 2021, 24 magnetars have been confirmed.
It has been suggested that magnetars are the source of fast radio bursts (FRB), in particular as a result of findings in 2020 by scientists using the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope.

B Neutron star 4U 1820-30 spins at 716 revolutions per second
I recently saw a short video describing some characteristics of neutron star, 4U 1820-30, in the Sagittarius constellation, i.e., in that direction. For some reason, it made the news recently, e.g., NICER X-ray Telescope Discovers Fast-Spinning Neutron Star, probably because some results were...- Astronuc
