Re: [nbos] [AS] Star density/frequency
Tue May 29th, 2007
My appologies for one error in those numbers. It is not .025 stars
per cubic light year. It is 0.039269908169872415480783042290994 stars
per cubic light year. Which makes the yield
2,570,209.4794503538069881486978844 stars. My appologies. (These
numbers were grabbed with the 'copy' function on my comp's calculator
and have not been adjusted for significant didgits in any way shape or
form.) It's still a much higher average density than 400,000 stars
than AS includes and sol's 'neighborhood' in space. Which means there
have to be some exceptionally dense regions out there if the edges
like Sol's area only have 42,000 in the area that 'galactic average'
says should have 2,570,209 stars give or take.
