New variable stars in NGC 6652 and its background Sagittarius stream
Ricardo Salinas, A. Katherina Vivas, Rodrigo Contreras Ramos
We conducted a variable star search on the metal-rich Galactic globular cluster NGC 6652 using archival Gemini-S/GMOS data. We report the discovery of nine new variable stars in th…
unVEil the darknesS of The gAlactic buLgE (VESTALE)
G. Bono, M. Dall'Ora, M. Fabrizio +55
The main aim of this experiment is to provide a complete census of old (t > 10 Gyr, RR Lyrae, type II Cepheids, red horizontal branch), intermediate age (red clump, Miras) and youn…
Discovery of Tidal RR LYRAE stars in the Bulge Globular Cluster M 62
Dante Minniti, José G. Fernández-Trincado, Vincenzo Ripepi +3
The RR Lyrae (RRL) rich globular cluster M 62 (NGC 6266) is one of the most massive globular clusters in the Milky Way, located in the dense region of the Galactic bulge, where dyn…
VVV Survey Microlensing: the Galactic Longitude Dependence
María Gabriela Navarro, Dante Minniti, Rodrigo Contreras Ramos
We completed the search for microlensing events in the zero latitude area of the Galactic bulge using the VVV Survey near-IR data obtained between 2010 and 2015. We have now a tota…
Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data
V. F. Braga, A. Bhardwaj, R. Contreras Ramos +5
Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. We trace t…
Milky Way demographics with the VVV survey. IV. PSF photometry from almost one billion stars in the Galactic bulge and adjacent southern disk
Javier Alonso-García, Roberto K. Saito, Maren Hempel +10
The inner regions of the Galaxy are severely affected by extinction, which limits our capability to study the stellar populations present there. The Vista Variables in the Via Lact…
The Orbit of the new Milky Way Globular Cluster FSR1716 = VVV-GC05
Rodrigo Contreras Ramos, Dante Minniti, Jose G. Fernandez-Trincado +10
We use deep multi-epoch near-IR images of the VISTA Variables in the Via Lactea (VVV) Survey to measure proper motions (PMs) of stars in the Milky Way globular cluster FSR1716 = VV…
