Measurements of 3He in Galactic HII regions and planetary nebulae
Published online by Cambridge University Press: 23 April 2010
Abstract
The cosmic abundance of the 3He isotope has important implications for many fields of astrophysics. We are using the 8.665 GHz hyperfine transition of 3He+ to determine the 3He/H abundance in Milky Way H ii regions and planetary nebulae. Here we review the 30 year history of our 3He program, report on its current status, and describe our future plans.
