Question

what are magnetars ? it is of astronomy please explain

Answer 1

A magnetar is a type of neutron star with an extremely powerful magnetic field. The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays.[1] The theory regarding these objects was proposed by Robert Duncan and Christopher Thompson in 1992, but the first recorded burst of gamma rays thought to have been from a magnetar had been detected on March 5, 1979.[2] During the following decade, the magnetar hypothesis became widely accepted as a likely
explanation for soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs).

Hope it helps!!
Cheers!!

Answer 2

Answer:

A magnetar is a type of neutron star believed to have 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.
