Betelgeuse star hot spots

Mysterious hot spots on Betelgeuse star

Scientists found mysterious hot spots in a red supergiant star.  Astronomers submitted the photo of an external layer of the atmosphere of a Betelgeuse star. It is the red supergiant next to Earth. It is very bright star located in constellation of Orion, which is the semiregular variable star which shine changes from 0,2 up to 1,2 star sizes and on the average makes near 0,7m. Red color of a star is easily noticeable at supervision by naked eye. The new photo of this star opens secrets of structure of substance, which proceeds from a star. In the photo on the right is visible the Betelgeuse star and her orbital circles. The photo was made by the camera of a radio telescope of MERLIN of Jodrell Bank Observatory. The Betelgeuse star is in 1000 of times massive from our Sun, but at distance of 650 light years from Earth, it still looks as a small point. In spite of the fact that it is a cold pro-evolving star, scientists found on it strange hot spots. These hot spots are on the opposite sides of a star, and their temperature reaches 4000-5000 degrees Kelvin, while the general temperature of a star doesn’t exceed 1 200 degrees Kelvin. The arches of cold gas proceeding from a star, stretch for 7,4 billions kilometers in a space. According to the doctor Anita Richards, the leading author of research from University of Manchester, is still unclear why hot spots on Betelgeuse star have such high temperature. Probably, it is provoked by a shock wave at a star pulsation.
