A collision of stars splashes radioactive particles in space

A collision of two stars can result in an astounding explosion which may lead to the formation of a new star. A similar event happened in 1670 where the viewers saw a blazing new star. Earlier it was visible to the naked eye but the light swiftly diminished and now telescopes are needed to view the leftovers of this collision. An international group of scientists analyzed the leftovers of this collision and found a conclusive design of the radioactive form of aluminium with atoms of fluorine which formed aluminium monofluoride.

It is the first particle carrying an unstable radioisotope conclusively found outside our solar system. These isotopes carry surplus nuclear energy which decomposes into steady form. Tomasz Kaminski, lead author in Nature Astronomy believes the finding of such radioactive particle to be a substantial landmark in exploring the molecular cosmos.

The astronomers found the rare pattern of these particles in the debris close to CK Vul which is at a distance of 2000 light years from the Earth. When these particles skid and turn in space, they radiate peculiar fingerprint of millimetre wavelength light. Scientists call this process rotational transition. These fingerprints are taken from experiments and are used to analyze particles in space.

Alexander Breier from the Kassel team said this method of calculation enables astronomers to decisively compute the rotational advances of 26AlF with an exactness needed for astronomical researchers.

The analysis of this specific isotope gives new bits of knowledge into the merger procedure that made CK Vul.
