Mark J. Reid,Karl M. Menten,Andreas Brunthaler,Xingwu Zheng,Thomas M. Dame,Ye Xu,J. J. Li,Nobuyuki Sakai,Yuefang Wu,K. Immer,Bo Zhang,Alberto Sanna,Luca Moscadelli,Kazi L.J. Rygl,A. Bartkiewicz,B. Hu,L. H. Quiroga-Nuñez,L. H. Quiroga-Nuñez,H. J. van Langevelde,H. J. van Langevelde +19 more
TL;DR: In this paper, the authors present an updated model for the structure of the Milky Way and incorporate it into the previously published parallax-based distance estimation program for sources associated with spiral arms.

TL;DR: In this article, the authors report parallaxes and proper motions of three water maser sources in high-mass star-forming regions in the Outer Spiral Arm of the Milky Way.

A Possible Extension of the Scutum-Centaurus Arm into the Outer Second Quadrant
TL;DR: In this article, a new segment of a spiral arm between Galactocentric radii of 15 and 19 kpc was identified, which apparently lies beyond the Outer Arm in the second Galactic quadrant.

TL;DR: A map of the Milky Way in three dimensions, based on the positions and distances of thousands of classical Cepheid variable stars, shows the structure of the Galaxy’s young stellar population and allows us to constrain the warped shape of the galactic disc.

Journal ArticleDOI
Local kinematics and the local standard of rest
TL;DR: In this article, the stellar kinematics of the solar neighbourhood in terms of the velocity υ� of the Sun with respect to the local standard of rest were examined. But the results were not robust to the metallicity gradient in the disc, which introduces a correlation between the colour of a group of stars and the radial gradients of its properties.

Disk-Satellite Interactions
Peter Goldreich,Scott Tremaine +1 more
TL;DR: In this article, the authors calculate the rate at which angular momentum and energy are transferred between a disk and a satellite which orbit the same central mass, and show that substantial changes in both the structure of the disk and the orbit of Jupiter must have taken place on a time scale of a few thousand years.

Local Kinematics and the Local Standard of Rest
TL;DR: In this article, the stellar kinematics of the Solar neighbourhood were examined in terms of the velocity of the Sun with respect to the local standard of rest. And the authors showed that the classical determination of its component V_sun in the direction of Galactic rotation via Stroemberg's relation is undermined by the metallicity gradient in the disc, which introduces a correlation between the colour of a group of stars and the radial gradients of its properties.

TL;DR: In this paper, the authors estimate the radius to the Galactic center, R-0, to be 8.34 +/- 0.16 kpc, a circular rotation speed at the Sun, Theta(0), to be 240 +/- 8 km s(-1), and a rotation curve that is nearly flat.
