Blue straggler stars beyond the Milky Way. IV. Radial distributions and dynamical implications

Chengyuan Li, Weijia Sun, Jongsuk Hong +3

Blue straggler stars have been proposeed as powerful indicators to measure the dynamical state of Galactic globular clusters. Here we examine for the first time if this framework o…

Mapping the Milky Way with LAMOST III: Complicated spatial structure in the outer disc

Hai-Feng Wang, Chao Liu, Yan Xu +2

We present {complexity} of the Galactic outer disc {by fitting the stellar volume densities of the red giant branch stars with a two-disc component model}. {The discs are confirmed…

An extremely low mid-infrared extinction law toward the Galactic Center and 4% distance precision to 55 classical Cepheids

Xiaodian Chen, Shu Wang, Licai Deng +1

Distances and extinction values are usually degenerate. To refine the distance to the general Galactic Center region, a carefully determined extinction law (taking into account the…

Optical-Mid-Infrared Period-Luminosity Relations for W UMa-type Contact Binaries Based on Gaia DR 1: 8% Distance Accuracy

Xiaodian Chen, Licai Deng, Richard de Grijs +2

W Ursa Majoris (W UMa)-type contact binary systems (CBs) are useful statistical distance indicators because of their large numbers. Here, we establish (orbital) period-luminosity r…

Disk stars in the Milky Way detected beyond 25 kpc from its center

M. Lopez-Corredoira, C. Allende Prieto, F. Garzon +3

CONTEXT. The maximum size of the Galactic stellar disk is not yet known. Some studies have suggested an abrupt drop-off of the stellar density of the disk at Galactocentric distanc…

3D Asymmetrical motions of the Galactic outer disk with LAMOST K giant stars

Haifeng Wang, Martín López-Corredoira, Jeffrey L. Carlin +1

We present a three dimensional velocity analysis of Milky Way disk kinematics using LAMOST K giant stars and the GPS1 proper motion catalogue. We find that Galactic disk stars near…
