"The Formation of Stars and Brown Dwarfs and the Truncation of Protoplanetary Discs in a Star Cluster
Matthew R. Bate, Ian A. Bonnell, and Volker Bromm
The calculation models the collapse and fragmentation of a molecular cloud with a mass 50 times that of our Sun. The cloud is initially 1.2 light-years (9.5 million million kilometres) in diameter, with a temperature of 10 Kelvin (-263 degrees Celsius). The cloud collapses under its own weight and very soon stars start to form. Surrounding some of these stars are swirling discs of gas which may go on later to form planetary systems like our own Solar System.
The calculation took approximately 100,000 CPU hours running on up to 64 processors on the UKAFF supercomputer. In terms of arithmetic operations, the calculation required approximately 1016 FLOPS (i.e. 10 million billion arithmetic operations).
Movie showing the full evolution of the system. Two versions, 94 seconds and 163 seconds, the latter of which shows the star formation sequence twice." (2 Formats .AVI and Quicktime)
