binary stars

The binary properties of massive stars

The physics of star formation remains an outstanding problem within astrophysics. This problem is particularly acute for the production of OB stars (with masses in excess of 20 times that of the Sun); where the apparent brevity of the process (<100,000 yrs) and the presence of significant extinction (>>30 visual magnitudes) due to their birth clouds, make observations of high mass protostars highly challenging.
