New kinematic map of the Milky Way bulge
Carlos Quezada, Manuela Zoccali, Elena Valenti +7
The kinematics of the Milky Way bulge is known to be complex, reflecting the presence of multiple stellar components with distinct chemical and spatial properties. In particular, t…
The Galactic Bulge exploration V.: The secular spherical and X-shaped Milky Way bulge
Z. Prudil, V. P. Debattista, L. Beraldo e Silva +9
In this work, we derive systemic velocities and subsequently orbits for 8456 RR~Lyrae stars. We identify interlopers from other Milky Way (MW) structures, which amount to 22 percen…
The Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation
Z. Prudil, A. Kunder, L. Beraldo e Silva +10
We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…
An "alien" called Oosterhoff dichotomy?
E. Luongo, V. Ripepi, M. Marconi +4
In this letter we investigate the origin of the Oosterhoff dichotomy, considering recent discoveries related to several ancient merging events of external galaxies with the Milky W…
Near-infrared observations of RR Lyrae and Type II Cepheid variables in the metal-rich bulge globular cluster NGC 6441
A. Bhardwaj, S. M. Kanbur, M. Rejkuba +4
NGC 6441 is a bulge globular cluster with an unusual horizontal branch morphology and a rich population of RR Lyrae (RRL) and Type II Cepheid (T2C) variables that is unexpected for…
Stellar density profile and mass of the Milky Way Bulge from VVV data
E. Valenti, M. Zoccali, O. A. Gonzalez +6
We present the first stellar density profile of the Milky Way bulge reaching latitude . It is derived by counting red clump stars within the colour\--magnitude diagram c…
A Sub-Earth-Mass Moon Orbiting a Gas Giant Primary or a High Velocity Planetary System in the Galactic Bulge
D. P. Bennett, V. Batista, I. A. Bond +90
We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M_host ~ 4 Jupiter masses hosting a sub-Eart…
Reddening and metallicity maps of the Milky Way bulge from VVV and 2MASS II. The complete high resolution extinction map and implications for Bulge studies
O. A. Gonzalez, M. Rejkuba, M. Zoccali +5
We use the Vista Variables in the Via Lactea (VVV) ESO public survey data to measure extinction values in the complete area of the Galactic bulge covered by the survey at high reso…
Alpha element abundances and gradients in the Milky Way bulge from FLAMES-GIRAFFE spectra of 650 K giants
O. A. Gonzalez, M. Rejkuba, M. Zoccali +9
We obtained FLAMES-GIRAFFE spectra (R=22,500) at the ESO Very Large Telescope for 650 bulge red giant branch (RGB) stars and performed spectral synthesis to measure Mg, Ca, Ti, and…
