Magnesium isotope ratios in Hyades stars
David Yong, David L. Lambert, Carlos Allende Prieto +1
Using classical model atmospheres and an LTE analysis, Mg isotope ratios 24Mg:25Mg:26Mg are measured in 32 Hyades dwarfs covering 4000K < Teff < 5000K. We find no significant trend…
Magnesium isotopic abundance ratios in cool stars
David Yong, David L. Lambert, Inese I. Ivans
From high resolution spectra of 61 cool dwarfs and giants, Mg isotopic abundance ratios 24Mg:25Mg:26Mg are derived from spectral synthesis of the MgH A-X lines near 5140A. Our samp…
Finding cool subdwarfs using a V-J reduced proper-motion diagram: Stellar parameters for 91 candidates
David Yong, David L. Lambert
We present the results of a search for cool subdwarfs for which our candidates were drawn from a V-J reduced proper-motion diagram constructed by Salim & Gould (2002). Kinematic (U…
Mg isotopic ratios in giant stars of the globular cluster NGC 6752
David Yong, Frank Grundahl, David L. Lambert +2
Mg isotopic abundance ratios are measured in 20 bright red giants in globular cluster NGC 6752 based on very high-resolution, high signal-to-noise spectra obtained with UVES on the…
