Researchers have found evidence of destroying themselves outside its orbit from a star in a “partial supernova” – now hurt on the Milky Way.
Around 40 percent of our Sun’s mass, this star is traveling at a speed of 559,234 mph.
Scientists at Britain’s University of Warwick note that the star, a white dwarf named SDSS J1240 + 6710, is an unusual composition. White dwarfs are very small dense stars that have exhausted their nuclear fuel.
In a statement by Warwick scientists at the University of Warwick, “The majority of white dwarfs are composed almost entirely of hydrogen or helium in the atmosphere, with occasional evidence of carbon or oxygen. However, researchers Said SDSS J1240 + 6710 contained neither hydrogen nor helium, but was composed of an unusual mixture of oxygen, neon, magnesium and silicon.
Scientists were also able to identify carbon, sodium, and aluminum using NASA’s Hubble Space Telescope. “The statement states,” However, there is a clear absence of elements, known as ‘iron groups’ of iron, nickel, chromium and manganese. “These heavier elements are usually lighter cooked and form the defining features of thermonuclear supernovae. The lack of iron group elements in SDSSJ1240 + 6710 suggests that the star underwent only a partial supernova before nuclear burning.”
This research is published in the monthly notice of the Royal Astronomical Society. Scientists from the Universidad Federal do Rio Grande do Sul in Brazil and Université Politecine de Catalunaya of Spain were also involved in the project.
“This star is unique because it has all the major characteristics of a white dwarf, but it has very high velocity and unusual abundance that makes no sense when combined with low mass,” said Professor Boris Gensike of the Department of Physics at the University . In Warwick’s statement. “It has a chemical structure that is a fingerprint of atomic burns, a low mass, and a very high velocity: all these facts mean that it must have come from some kind of close binary system and had thermonuclear ignition.”
The star would have been a type of supernova, but one of a kind not seen before, Gensike said.
In a separate project, astronomers in Japan have observed a large “superflare” emerging from a nearby star.
Researchers at Kyoto University and Japan’s National Astronomical Observatory discovered a red dwarf 16 light-years away. Detected 12 stellar flows over Leonis. One light year, which measures the distance in space, is equal to about 6 trillion miles.
Red dwarf stars are the smallest and most abundant stars in our galaxy. They are also the longest surviving stars.
