Scientists know the Binary Star System Cosmic Sermic & # 39; Creating Gamma-Ray Breaks



A great part of the great, and even fear, behind space sciences is that it offers a true picture of the random and unpredictable set of cosmic phenomena that may be around our planet at any given time.

Amongst all, star systems seem to capture our attention in a more dynamic way, most likely due to their potential to shoot cosmic rays in the Earth, but in some cases, such as terrestrial gamma gamma flashes (TGF), the source unexpected to be a hurricane storm activity.

Now, researchers are investigating the behavior of one of the most exciting and incredible star systems in the galaxy, Wolf-Rayet stars, and more importantly, the role of the dust cloud that moves rapidly around the system creates long-term gaming rays (GRB). Named the 2XMM J160050.7-514245, the Wolf-Rayet system also passes through the Apep nickname, and seats within a contrast of the Norma name, or Carpenter Square (Ble, or where do astronomers get these names?).

In the case of Apep, however, the name is a reference to the ancient Egyptian image of the same name in the form of a large serpent, and given the uncoordinated nature of the system's unique shape, the name & # 39; n more than fit. First, the VISIR European Observatory of Europe (ESO) tool captured the system first.

Track the GRBs Delete

GRB, some of the most powerful and short explosions in the whole universe, can last as long as a few hours or as few as a few thousand seconds. If their life passes the two seconds mark, they can be considered as a long-lasting GRB.

Below is a video of the process that is sensitive to time that goes to tracking GRBs:

On the one hand, Apep's huge wind moves at a rate of 12 million kph based on ESO measurements, while the dust pinch travels at a slower rate two million kph, which the team believes it is because the wind is being launched in different directions. In either way, the evidence of the GRB phenomenon shows to the researchers that the star system moves at such a spectacular speed because it is a type of suicide mission.

Regardless of the case, the team are proud of the opportunity to comment on this. It's a rare opportunity to comment on a dynamic star system, which, given the dynamic combination of factors associated with the formation of GRB as well as the Wolf-Rayet star systems, it seems that excitement & The excitement is good.

"This is the system of the first kind found in our own galaxy," explained Joseph Callingham of the Netherlands Radio Radio Foundation (ASTRON), leading author of the study that reports This system, adding "We had never expected to find such a system in our own backyard."

Details of the study appear in a paper, known as "Bluetooth anisotropic devices in Wolf-Rayet identifying a possible gamma manufacturer", published November 19 in Astronomy of Nature magazine.
