Astronomers have now detected a binary star system with the closest high-mass young stellar objects ever measured, providing a standard "laboratory" to test the theories on high binary star formation.
The distance between the two binary star has been discovered to be PDS 27 and its orbiting stellar companion to be 30 astronomical units away, or 4.5 billion Km by an international team led by the University of Leeds.
This is the approximate distance between the sun and Neptune, making them the stellar companions with the closest proximity ever determined for young high mass stars in a binary system - a star system with two stars revolving around a centre of mass.
Dr Eugenia Koumpia, from School of Physics and Astronomy at Leeds, said, "this is a very interesting discovery, observing and stimulating massive binaries at the initial stages of their development is one of the major difficulty of modern astronomy. But with PDS 27 and its companion, we have found the closest, most massive young stellar objects in binaries resolved to date."
