HST astrometry in the 30 Doradus region: measuring proper motions of individual stars in the Large Magellanic Cloud
I. Platais, R. P. van der Marel, D. J. Lennon +5
We present measurements of positions and relative proper motions in the 30 Doradus region of the Large Magellanic Cloud (LMC). We detail the construction of a single-epoch astromet…
High-precision astrometry with VVV. I. An independent reduction pipeline for VIRCAM@VISTA
M. Libralato, A. Bellini, L. R. Bedin +6
We present a new reduction pipeline for the VIRCAM@VISTA detector and describe the method developed to obtain high-precision astrometry with the VISTA Variables in the Vía Láctea (…
A spin-down clock for cool stars from observations of a 2.5-billion-year-old cluster
Soren Meibom, Sydney A. Barnes, Imants Platais +3
The ages of the most common stars - low-mass (cool) stars like the Sun, and smaller - are difficult to derive because traditional dating methods use stellar properties that either…
The Nature and Orbit of the Ophiuchus Stream
B. Sesar, J. Bovy, E. J. Bernard +20
The Ophiuchus stream is a recently discovered stellar tidal stream in the Milky Way. We present high-quality spectroscopic data for 14 stream member stars obtained using the Keck a…
