The [Y/Mg] clock works for evolved solar metallicity stars
D. Slumstrup, F. Grundahl, K. Brogaard +5
Previously [Y/Mg] has been proven to be an age indicator for solar twins. Here, we investigate if this relation also holds for helium-core-burning stars of solar metallicity. High…
An investigation of the formation and line properties of MgH in 3D hydrodynamical model stellar atmospheres
Anders O. Thygesen, Evan N. Kirby, Andrew J. Gallagher +4
Studies of the isotopic composition of magnesium in cool stars have so far relied upon the use of one-dimensional (1D) model atmospheres. Since the isotopic ratios derived are base…
Triangulum II: Not Especially Dense After All
Evan N. Kirby, Judith G. Cohen, Joshua D. Simon +3
Among the Milky Way satellites discovered in the past three years, Triangulum II has presented the most difficulty in revealing its dynamical status. Kirby et al. (2015a) identifie…
The age of 47Tuc from self-consistent isochrone fits to colour-magnitude diagrams and the eclipsing member V69
K. Brogaard, D. A. VandenBerg, L. R. Bedin +3
Our aim is to derive a self-consistent age, distance and composition for the globular cluster Tucanae (Tuc; NGC104). First, we reevaluate the reddening towards the clus…
