Latest Magnetar Stories
X-ray and gamma-ray data from ESAâ€™s XMM-Newton and Integral orbiting observatories has been used to test, for the first time, the physical processes that make magnetars, an atypical class of neutron stars, shine in X-rays.
Astronomers have discovered a most bizarre celestial object that emitted 40 visible-light flashes before disappearing again. It is most likely to be a missing link in the family of neutron.
MIDLAND, Texas, Sept.
A new NASA mission could discover the shape of space that has been distorted by a spinning black hole's crushing gravity, and explore the structure and effects of the formidable magnetic field around magnetars.
NASA's Spitzer Space Telescope has found a bizarre ring of material around the magnetic remains of a star that blasted to smithereens.
Like something out of a Robert Louis Stevenson novel, researchers at NASA and McGill University discovered an otherwise normal pulsar which violently transformed itself temporarily into a magnetar, a stellar metamorphosis never observed before.
With eyes that peer into the most energetic phenomena in the universe, ESAâ€™s Integral has been setting records, discovering the unexpected and helping understanding the unknown over its first five years.
University of Arizona astronomers have pinpointed the origin of powerful bursts from nature's most magnetic objects. The bursts are from "magnetars," some of the most enigmatic objects in the universe.
Astronomers using data from several X-ray satellites have caught a magnetar â€“ the remnant of a massive star with an incredibly strong magnetic field â€“ in a sort of giant cosmic blench.
NASA's Swift satellite has challenged some of astronomers' fundamental ideas about gamma-ray bursts (GRBs), which are among the most extreme events in our universe.
X-ray Pulsar -- This dramatic artist's vision shows a city-sized neutron star centered in a disk of hot plasma drawn from its enfeebled red companion star. Ravenously accreting material from the disk, the neutron star spins faster and faster emitting powerful particle beams and pulses of X-rays as it rotates 400 times a second. Could such a bizarre and inhospitable star system really exist in our Universe? Based on data from the orbiting Rossi X-Ray Timing Explorer (RXTE) satellite,...
Pulsar -- A pulsar, which originally stood for pulsating radio source, is a rapidly rotating neutron star, whose electromagnetic radiation is observed in regularly spaced interval, or pulses. Pulsars are closely related to magnetars, the main difference being the strenght of the object's magnetic field. History Pulsars were discovered by Jocelyn Bell and Antony Hewish in 1967 while they were using a radio array to study the scintillation of quasars. They found a very regular...
Magnetar -- A magnetar is a neutron star with a strong magnetic field. The theory around these objects was formulated by Robert Duncan and Christopher Thompson. When in a supernova a star collapses to a neutron star, its magnetic field increases dramatically in strength. Duncan and Thompson calculated that the magnetic field of a neutron star, normally an already enormous 1012 tesla could under certain circumstances grow even larger, to about 1015 tesla. Such a highly magnetic neutron...
