The peculiar in-plane velocities in the outer disc of the Milky Way
Hai-Jun Tian, Chao Liu, Jun-Chen Wan +9
We present the peculiar in-plane velocities derived from the LAMOST red clump stars, which are purified and separated by a novel approach into two groups with different ages. The s…

A Gaia-PS1-SDSS (GPS1) Proper Motion Catalog Covering 3/4 of the Sky
Hai-Jun Tian, Prashansa Gupta, Branimir Sesar +7
We combine Gaia DR1, PS1, SDSS and 2MASS astrometry to measure proper motions for 350 million sources across three-fourths of the sky down to a magnitude of \,. Using po…

The age-kinematical features in the Milky Way outer disk
Chao Liu, Hai-Jun Tian, Jun-Chen Wan
We derive the mean velocity components at various Galactocentric radii from 8 to 14 kpc using about 40,000 red clump stars observed in the LAMOST survey. We find that the vertical…
