Stars with fast Galactic rotation observed in Gaia TGAS: a signature driven by the Perseus arm?
Jason A. S. Hunt, Daisuke Kawata, Giacomo Monari +3
We report on the detection of a small overdensity of stars in velocity space with systematically higher Galactocentric rotation velocity than the Sun by about 20 km s in the…
Tracing the Hercules stream with Gaia and LAMOST: new evidence for a fast bar in the Milky Way
Giacomo Monari, Daisuke Kawata, Jason A. S. Hunt +1
The length and pattern speed of the Milky Way bar are still controversial. Photometric and spectroscopic surveys of the inner Galaxy, as well as gas kinematics, favour a long and s…
Detection of a dearth of stars with zero angular momentum in the solar neighbourhood
Jason A. S. Hunt, Jo Bovy, Raymond G. Carlberg
We report on the detection in the combined -DR1/RAVE data of a lack of disk stars in the solar neighbourhood with velocities close to zero angular momentum. We propose that t…
Impacts of a Flaring Star-forming Disc and Stellar Radial Mixing on the Vertical Metallicity Gradient
D. Kawata, R. J. J. Grand, B. K. Gibson +3
Using idealised N-body simulations of a Milky Way-sized disc galaxy, we qualitatively study how the metallicity distributions of the thin disc star particles are modified by the fo…
