Untangling the Galaxy. II. Structure within 3kpc J/AJ/160/279 ivo://CDS.VizieR/J/AJ/160/279 doi:10.26093/cds/vizier.51600279 CDS Kounkel M. Covey K.

The current paper builds on the sample from the previous work, extending it in distance from 1 to 3kpc and increasing the number of identified structures up to 8292. To aid in the analysis of the population properties, we developed a neural network called Auriga to robustly estimate the age, extinction, and distance of a stellar group based on the input photometry and parallaxes of the individual members. We apply Auriga to derive the properties of not only the structures found in this paper, but also previously identified open clusters. Through this work, we examine the temporal structure of the spiral arms. Specifically, we find that the Sagittarius Arm has moved by >500pc in the last 100Myr and the Perseus Arm has been experiencing a relative lull in star formation activity over the last 25Myr. We confirm the findings of the previous paper on the transient nature of the spiral arms, with the timescale of transition of a few 100Myr. Finally, we find a peculiar ~1Gyr old stream of stars that appears to be heliocentric. Its origin is unclear. 2020AJ....160..279K https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/279 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to B/ocl : Optically visible open clusters and Candidates (Dias+, 2002-2015) I/345 : Gaia DR2 (Gaia Collaboration, 2018) I/349 : StarHorse, Gaia DR2 photo-astrometric distances (Anders+, 2019) J/A+A/558/A53 : Milky Way global survey star clusters.
