Title: Stellar Populations in the Cosmological Context: Day 1

The Space Telescope Science Institute is currently hosting their annual May Symposium. This year, it’s on “Stellar Populations in the Cosmological Context“. The official abstract for the meeting claims “The 2010 May Symposium aims at understanding the physical processes and observational characteristics of local stellar populations as a tool for elucidating the evolution of general stellar populations throughout cosmic history”, but I prefer to think of it as “Hey! Galaxies are made of STARS! We might learn something if we actually look at them!”

Oh it's very interesting.  But the bit that amused me was:

Bosch et al 2009 dropped the velocity dispersion of the cluster from 35 km/s to 8 km/s, by correcting for the motions of stars in binaries (2/3rds of the massive stars)

Centuries of science had been forgotten!   ::)
