High-fidelity stellar extinction with Gaia and APOGEE -- I. The method and a new extinction curve
Jie Yu, Luca Casagrande, John A. Taylor +9
The scarcity of high-fidelity extinction measurements remains a bottleneck in deriving accurate stellar properties from Gaia parallaxes. In this work, we aim to derive precision ex…
New Evidence of Binarity in Young α-Rich Turn-off and Subgiant Stars: Fast Rotation and Strong Magnetic Activity
Jie Yu, Luca Casagrande, Ioana Ciucă +3
Young α-rich (YAR) stars within the old Galactic thick disk exhibit a dual characteristic of relative youth determined with asteroseismology and abundance enhancement in α elements…
Cool and Data-Driven: An Exploration of Optical Cool Dwarf Chemistry with Both Data-Driven and Physical Models
Adam D. Rains, Thomas Nordlander, Stephanie Monty +6
Detailed chemical studies of F/G/K -- or Solar-type -- stars have long been routine in stellar astrophysics, enabling studies in both Galactic chemodynamics, and exoplanet demograp…
On the AGB stars of M 4: A robust disagreement between spectroscopic observations and theory
B. T. MacLean, S. W. Campbell, A. M. Amarsi +7
Several recent spectroscopic investigations have presented conflicting results on the existence of Na-rich asymptotic giant branch (AGB) stars in the Galactic globular cluster M4 (…
AGB subpopulations in the nearby globular cluster NGC 6397
B. T. MacLean, S. W. Campbell, G. M. De Silva +5
It has been well established that Galactic Globular clusters (GCs) harbour more than one stellar population, distinguishable by the anti-correlations of light element abundances (C…
Fundamental Properties of Stars using Asteroseismology from Kepler & CoRoT and Interferometry from the CHARA Array
D. Huber, M. J. Ireland, T. R. Bedding +37
We present results of a long-baseline interferometry campaign using the PAVO beam combiner at the CHARA Array to measure the angular sizes of five main-sequence stars, one subgiant…
