Similar to all supernovae, the luminosity of metal - poor supernovae show a characteristic rise to a peak brightness followed by a decline.
«So far we have doubled the peak and average «luminosity» - measures that are directly related to the collision rates,» said Wolfram Fischer, Associate Chair for Accelerators of Brookhaven's Collider - Accelerator Department and lead author on a paper describing the success just published in Physical Review Letters.
The YSO mass function (MF), constructed using a theoretical mass - luminosity relation, shows peaks at substellar (~ 0.08 - 0.18 Msolar) and intermediate (~ 1 - 1.78 Msolar) mass ranges for the IRS 1 - 3 region.
The peak absolute luminosity appears to be about 50,000 times the luminosity of the Sun, but the largest percentage of known open clusters has a brightness equivalent to 500 solar luminosities.
