A Larger Extent for the Ophiuchus Stream
N. Caldwell, A. Bonaca, A. Price-Whelan +2
We present new kinematic data for the Ophiuchus stellar stream. Spectra have been taken of member candidates at the MMT telescope using Hectospec, Hectochelle and Binospec, which p…
The extended Gaia-PS1-SDSS (GPS1+) proper motion catalog
Hai-Jun Tian, Yang Xu, Chao Liu +3
The GPS1 catalog was released in 2017. It delivered precise proper motions for around 350 million sources across three-fourths of the sky down to a magnitude of \,mag. In…
On the use of field RR Lyrae as Galactic probes: I. The Oosterhoff dichotomy based on fundamental variables
M. Fabrizio, G. Bono, V. F. Braga +21
We collected a large data set of field RR Lyrae stars (RRLs) by using catalogues already available in the literature and Gaia DR2. We estimated the iron abundances for a sub-sample…
Connecting the Milky Way potential profile to the orbital timescales and spatial structure of the Sagittarius Stream
Mark A. Fardal, Roeland P. van der Marel, David R. Law +4
Recent maps of the halo using RR Lyrae from Pan-STARRS1 have clearly depicted the spatial structure of the Sagittarius stream. These maps show the leading and trailing stream apoce…
Two chemically similar stellar overdensities on opposite sides of the plane of the Galaxy
Maria Bergemann, Branimir Sesar, Judith G. Cohen +9
Our Galaxy is thought to have undergone an active evolutionary history dominated by star formation, the accretion of cold gas, and, in particular, mergers up to 10 gigayear ago. Th…
A Disk Origin for the Monoceros Ring and A13 Stellar Overdensities
Allyson A. Sheffield, Adrian M. Price-Whelan, Anastasios Tzanidakis +3
The Monoceros Ring (also known as the Galactic Anticenter Stellar Structure) and A13 are stellar overdensities at estimated heliocentric distances of kpc and 15 kpc obs…
