Orion Block V1647 stellar explosions illuminated McNeil star cloud. In this artistic interpretation of the magnetic field driven by the strong airflow came to the star, creating two hot spots of the manufacture of high-energy rays.

McNeil star cloud: the protostar Orion V1647 McNeil star cloud top. The scientists found that in an explosion near the vertex of January 2004 Fengyun protostar.

The yellow line represents the Orion the V1647 star X-ray periodic emission: two hot spots (green and red lines) X-ray production is located in both ends of the star.NASA scientists as the interstellar midwife "as careful monitoring of a local young star still in the interstellar cloud infant. Astronomers use data from 3 surrounded by orbiting X-ray telescope is extremely rare to find a powerful phenomenon with new star formation.NASA is monitoring "Orion V1647 stars have been observed to a strong magnetic field driven airflow to the star's surface, these broad areas the air is heated to millions of degrees, which makes that this new stars rapidly rotating hot the release of the X-ray. This explosion of new stars X-ray energy will make it to brighten 100-fold.In January 2004, astronomers in an explosion near the vertex of the first note of this young star. The explosion of this new star became very bright, that illuminate one now known as McNeil star cloud "conical dust. This new stars and nebulae from the constellation Orion constant, about 1,300 light-years. Astronomers soon Orion V1647 was a star of the original star, which is still a local young stars in the interstellar clouds in their infancy,The study of the person in charge of NASA's Goddard Space Flight Center astrophysicist Hamaguchi Kenji (Kenji Hamaguch) said: "According to the infrared study, we speculate that this protostar age of less than 100 years, or even young protostar has not yet evolved the ability of a normal star like the sun to generate energy. Solar hydrogen and its core nitrogen together. Orion V1647 stars, the next needed millions of years before entering this stage. Prior to this, this protostar can only rely on continuously fell on its surface, the gas release of heat and light, most of them gas from a discoid region around the stellar rotation.Most of the Orion V1647 star is likely to only 80% of the sun, but its low density so that after the expansion than the sun, nearly five times. Infrared measurements show that in most parts of the star surface temperature is about 6400 degrees Fahrenheit (about 3,500 degrees Celsius), of which about one-third region is colder than the sun. However, during the explosion in 2003, this protostellar X-ray brightness of 100 times, while launching the X-ray region, the temperature reaches about 90 million degrees Fahrenheit (about 50 million degrees Celsius).2008, an explosion broke July 13, 2012. Explosion, the changes in the brightness of the light and infrared wavelengths is likely to be caused by changes in this protostar the dominant energy source. Due to the change of light and infrared brightness of the X-ray immediately changed, so the high-energy missile inevitable and the brightness increases.The study is responsible for one - Joel Kastner said: "Taking into account the Orion V1647 star is about 5 times than the sun, rapid rotation confirmed that we are observing a young star pulled together." cyclical changes of the X-ray appearance change and disappearance of the star hot zone.The researchers said the most consistent with the observations of the model consists of two brightness ranging from hot spots at the ends of the star. They believe that these two hot spots into the sun size, shaped like a pancake regions, but more hot south about 5 times higher brightness. These hot spots represent the footprint of the discoid region of the accretion flow to the magnetic effect of this young star surface.In order to achieve the high-temperature X-ray emission, the material is bound to hit about 4.5 million miles per hour speed this protostar. A result, these hot spots to achieve a higher temperature than all other places of the star about 1.3 times. The star and discoid region has a magnetic field around its operation. As the star is rotating faster than the discoidal area, so the magnetic field is distorted, like a taut rubber band, the same stored energy. This chaos into a ball of a magnetic field to adjust into a more stable state, a strong explosion in the form of sudden release of stored energy. This is called "magnetic reconnection" process also provided the impetus for the solar X-ray flare.Although these physical processes may be very similar, but their time scales are significantly different. A solar flare X-ray production can only lasted less than a few minutes. Orion V1647 star explosions continued for several years. In contrast, the strongest solar flares on record is an X28-class solar flare erupted in November 4, 2003. Hamaguchi Kenji infer that the stability of the X-ray brightness Orion V1647 star produced by the explosion thousands of times higher than the peak brightness of the solar flare.What caused the explosion of the star it? Astronomers do not know. They suppose, gradually built a medial discoid area closer to the star within the the discoid regional part of the gas outside in the way. Very active magnetic be opened only when the limit is reached, but once it did so the gas will flow quickly to hot spots, produce X-rays.Orion V1647 star explosion, astronomers are now using Chandra, Suzaku, and X-ray lens - Newton telescope a sun in the stars of the "infancy".
