Astronomers find a binary star system that will go supernova

An international team of astronomers led by researchers from the University of Warwick has made a very interesting discovery. The team has found a binary star system that leads to supernova, which is very rare. The tellaale sign from the binary system towards his death is a star in the form of tear droplets.

The shape is caused by a large and closest white dwarf distorting stars with intense gravity. Intense gravity is a catalyst for supernova finally who will consume stars. The binary duo is one of only a small number of star systems found one day will see white dwarf stars revive the point.

The researchers published a study that revealed that binary pairs were in the initial phase of spirals which are expected to end with the type of supernova, a type of supernova who can help astronomers determine how fast the universe develops. Astronomers are nicknamed pair HD265435, and they are around 1500 light years. It consists of hot subdwarf stars and white dwarf stars orbiting each other closely with a 100 minute orbital rate.

White dwarf star is a star whose fatigue of all the fuel and collapses by itself, makes it very small but very crowded. A type supernova he believed to occur when a white Dwarf turned on the core which led to a thermal nuclear explosion. Astronomers say there are two situations where this happens. The first to see white Dwarf get enough mass to reach 1.4 times the mass of our Sun, known as the Chandrasekhar limit.

HD265435 is expected to match the second scenario, where the total mass of the star system several stars near or above the limit. The researchers only found a small number of star systems that would reach the chandrasekhar limit and produce the type of supernova. Astronomers observed a hot subdwarf star using data from the satellite survey of NASA’s exoplanet transit but could not see white dwarf because his companion was far brighter. White Dwarf is expected to be a supernova in around 70 million years.
