APOGEE Kinematics I: Overview of the Kinematics of the Galactic Bulge as Mapped by APOGEE
M. Ness, G. Zasowski, J. A. Johnson +12
We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky Way. APOGEE includes…
Spectroscopic determination of masses (and implied ages) for red giants
M. Ness, David W. Hogg, H-W. Rix +3
The mass of a star is arguably its most fundamental parameter. For red giant stars, tracers luminous enough to be observed across the Galaxy, mass implies a stellar evolution age.…
Red giant masses and ages derived from carbon and nitrogen abundances
Marie Martig, Morgan Fouesneau, Hans-Walter Rix +7
We show that the masses of red giant stars can be well predicted from their photospheric carbon and nitrogen abundances, in conjunction with their spectroscopic stellar labels log…
The Metallicity Distribution of the Milky Way Bulge
M. Ness, K. Freeman
The Galactic bulge of the Milky Way is made up of stars with a broad range of metallicity, -3.0 < [Fe/H] < 1 dex. The mean of the Metallicity Distribution Function (MDF) decreases…
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
A Kiloparsec-Scale Nuclear Stellar Disk in the Milky Way as a Possible Explanation of the High Velocity Peaks in the Galactic Bulge
Victor P. Debattista, Melissa Ness, Samuel W. F. Earp +1
The Apache Point Observatory Galactic Evolution Experiment has measured the stellar velocities of red giant stars in the inner Milky Way. We confirm that the line of sight velocity…
