A Chemical Composition Survey of the Iron-Complex Globular Cluster NGC 6273 (M 19)
Christian I. Johnson, Nelson Caldwell, R. Michael Rich +5
Recent observations have shown that a growing number of the most massive Galactic globular clusters contain multiple populations of stars with different [Fe/H] and neutron-capture…
A 3D Search for Companions to 12 Nearby M-Dwarfs
Cassy L. Davison, Russel J. White, Todd J. Henry +7
We present a carefully vetted equatorial ( 30 Decl.) sample of all known single (within 4'') mid M-dwarfs (M2.5V-M8.0V) extending out to 10 pc; their proximity and low…
AGB Sodium Abundances in the Globular Cluster 47 Tucanae (NGC 104)
Christian I. Johnson, Iain McDonald, Catherine A. Pilachowski +8
A recent analysis comparing the [Na/Fe] distributions of red giant branch (RGB) and asymptotic giant branch (AGB) stars in the Galactic globular cluster NGC 6752 found that the rat…
