Dramatic flares and bursts of energy - activity previously thought reserved for only the strongest magnetized pulsars - have been observed emanating from a weakly magnetized, slowly rotating pulsar. The international team of astrophysicists who made the discovery believe that the source of the pulsar's power may be hidden deep within its surface. Pulsars, or neutron stars, are the collapsed remains of massive stars. Although they are on average only about 30km in diameter, they have hugely...

A team of European researchers have pinpointed a magnetar--an unusual type of neutron star that possesses an immensely powerful magnetic field--that was formed by a star that had at least 40 times more mass than our solar system's sun.The discovery, they say, could force scientists to rethink current theories of star evolution, and specifically, the amount of mass needed to form a black hole.According to the scientific website PhysOrg.com, "This proves for the first time that magnetars can...

NASA EDGE, an award-winning talk show known for offbeat, funny and informative behind-the-scene stories about the space agency, will celebrate Sun-Earth Day 2010, with a live webcast about our sun and its effects on Earth. The program will air at 1 p.m. EDT, Saturday, March 20, from the exhibit floor of the National Science Teachers Association conference in Philadelphia. This year's focus is magnetic storms created by the sun. Magnetism, a force that affects our everyday lives, plays a key...

Astronomers using the U.S. space agency's Swift satellite and Fermi Gamma-ray Space Telescope report high-energy gamma-ray bursts from a neutron star. National Aeronautics and Space Administration scientists said the object -- a rare type of neutron star known as a soft-gamma-ray repeater -- is emitting intense and frequent X-ray and gamma-ray flares. At times, this remarkable object has erupted with more than a hundred flares in as little as 20 minutes, said Loredana Vetere, who is...

WASHINGTON, Feb. 10 /PRNewswire-USNewswire/ -- Astronomers using NASA's Swift satellite and Fermi Gamma-ray Space Telescope are seeing frequent blasts from a stellar remnant 30,000 light-years away. The high-energy fireworks arise from a rare type of neutron star known as a soft-gamma-ray repeater. Such objects unpredictably send out a series of X-ray and gamma-ray flares.

The quick turn-around time of the INTEGRAL operation teams has enabled rare high-energy observations of a magnetar. The observations, which were performed as a Target of Opportunity, followed indications late last week that this magnetar, the Anomalous X-ray Pulsar, 1E 1547.0-5408, had entered outburst mode. 1E1547.0-5408 is one of only 9 confirmed Anomalous X-ray Pulsars (AXP) - isolated, young neutron stars with unusually strong magnetic fields (1014G -1015G). Together with Soft Gamma...

XMM-Newton has caught the fading glow of a tiny celestial object, revealing its rotation rate for the first time. The new information confirms this particular object as one of an extremely rare class of stellar zombie "“ each one the dead heart of a star that refuses to die. There are just five so-called Soft Gamma-ray Repeaters (SGRs) known, four in the Milky Way and one in our satellite galaxy, the Large Magellanic Cloud. Each is between 10 and 30 km across, yet contains about twice...

X-ray and gamma-ray data from ESA'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. Neutron stars are remnants of massive stars (10-50 times as massive as our Sun) that have collapsed on to themselves under their own weight. Made almost entirely of neutrons (subatomic particles with no electric charge), these stellar corpses concentrate more than the mass...

First Optically Active Magnetar-Candidate Discovered 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. This weird object initially misled its discoverers as it showed up as a gamma-ray burst, suggesting the death of a star in the distant Universe. But soon afterwards, it exhibited some unique behaviour that indicates its origin is much closer to us....

MIDLAND, Texas, Sept. 24, 2008 (GLOBE NEWSWIRE) -- Legacy Reserves LP (Nasdaq:LGCY) today announced that is has entered into a commitment to invest up to $20 million over three years with Black Oak Resources, LLC ("Black Oak"), a partnership between Mike Black, and a partnership formed by Post Oak Energy Capital, LP ("Post Oak") and Magnetar Capital ("Magnetar"). Black Oak and Legacy will jointly pursue oil and natural gas assets which have a high percentage of undeveloped reserves. The...

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...
