Scientists believe that after hundreds of years of the explosion again.
Astrophysics from Poland, the US and the UK observed the explosion of a white dwarf — the birth of a classic supernova.
A study published in the journal Nature.
Surveillance conducted since 2003 in the framework of the project OGLE (Optical Gravitational Lensing Experiment), the fixed periodic change of the luminosity of the star V1213 Cen, which culminated in the explosion of a supernova in 2009.
Scientists have noted a low rate of mass transfer between stars in a binary system V1213 Cen. Reset shell white dwarf began six days after the last fall of his luminosity.
Astronomers say that they were able to directly observe the supernova explosion and confirm the theory that describes the mass transfer between companions in a binary system. Scientists believe that after hundreds of years of the explosion, accompanied by a short-term increase of three orders of magnitude brightness of a star, again.
Properties of binary system in this case depends on the mass transfer rate — how quickly matter with a small companion falls onto a white dwarf.
