Astronomers Find Youngest-Ever X-Ray Binary
2013-12-05 06:29:43

[ Watch the Video: Millisecond Pulsar with Magnetic Field Structure ] redOrbit Staff & Wire Reports - Your Universe Online Using data obtained from NASA's Chandra X-ray Observatory and the Australia Telescope Compact Array, researchers have identified the remains of a supernova that exploded just 2,500 years ago, making it the youngest astronomical object of its kind ever discovered. The object is an X-ray binary located between 24,000 and 30,000 light years from Earth in the...

Millisecond Pulsars: The Discovery Of Deceleration
2012-02-03 08:16:23

Stellar astrophysics helps to explain the behavior of fast rotating neutron stars in binary systems Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometers, but at the same time roughly the mass of our sun. A sugar-cube sized piece of its ultra-compact matter on the Earth would weigh hundreds of millions of tons. A sub-class of them, known as millisecond pulsars, spin up to several hundred times per second around their own axes. Previous...

Black Hole Birth Announcement
2011-11-17 14:40:32

For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise measurements have allowed them to reconstruct the history of the object from its birth some six million years ago. Using several telescopes, both ground-based and in orbit, the scientists unraveled longstanding mysteries about the object called Cygnus X-1, a famous binary-star system discovered...

Using two NASA X-ray satellites, astronomers have discovered what drives the "heartbeats" seen in the light from an unusual black hole system. These results give new insight into the ways that black holes can regulate their intake and severely curtail their growth. This study examined GRS 1915+105 (GRS 1915 for short), a binary system in the Milky Way galaxy containing a black hole about 14 times more massive than the Sun that is feeding off material from a companion star. As this material...

NASA's Fermi Gamma-ray Space Telescope has made the first unambiguous detection of high-energy gamma-rays from an enigmatic binary system known as Cygnus X-3. The system pairs a hot, massive star with a compact object -- either a neutron star or a black hole -- that blasts twin radio-emitting jets of matter into space at more than half the speed of light. Astronomers call these systems microquasars. Their properties -- strong emission across a broad range of wavelengths, rapid brightness...

A team of scientists, including researchers in the University of Southampton's School of Physics and Astronomy, has shown that black holes are not the only known objects in the universe to produce infrared light from beams of particles being shot into space at nearly the speed of light. Previously, these steady "Ëœrelativistic jets' were only seen from black holes which form part of a black hole X-ray binary, a system containing a black hole orbited by a normal star which is so...

A team of astronomers from The Netherlands and the UK has discovered a vast "Ëœjet-powered bubble' formed in the gas around a black hole in the Milky Way.   The discovery means that for decades scientists have been severely underestimating how much power black holes pump back into the universe instead of merely swallowing material across their event horizons. Jets of energy and particles flowing outwards at close to the speed of light are a common feature of all accreting...

Cygnus X-1 -- Cygnus X-1 (often abbreviated to Cyg X-1) is an X-ray source in the Cygnus constellation considered to be one of the most likely black hole candidates. The optical counterpart (HDE 226868) is a variable 8.9 magnitude star (visible with good binoculars in good observing conditions.) at right ascension 19 h 56.5 min and declination of 35 deg 4 min (for 1950 epoch). Cyg X-1 is a binary star that contains a O9-B0 supergiant (with a surface temperature of 31000 Kelvin) and a...
