Characterization of the VVV Survey RR Lyrae Population across the Southern Galactic Plane

Autor: Minniti, D. Dékány, I. Majaess, D. Palma, T. Pullen, J. Rejkuba, M. Alonso-García, J. Catelan, M. Contreras Ramos, R. Gonzalez, O.A. Hempel, M. Irwin, M.l Lucas, P.W. Saito, R.K. Tissera, P. Valenti, E. Zoccali, M.

Deep near-IR images from the VISTA Variables in the Via Lactea (VVV) Survey were used to search for RR Lyrae stars in the Southern Galactic plane. A sizable sample of 404 RR Lyrae of type ab stars was identified across a thin slice of the fourth Galactic quadrant (295 degrees < l < 350 degrees, -...

Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data

Autor: Braga, V.F. Bhardwaj, A. Contreras Ramos, R. Minniti, D. Bono, G. De Grijs, R. Minniti, J.H. Rejkuba, M.

Context. Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. Aims. We trace the structure of old stellar population in the Galactic bulge using new distance estimates and kinemati...

Pulsating stars in ω Centauri. Near-IR properties and period-luminosity relations

Autor: Navarrete, C. Catelan, M. Contreras Ramos, R. Alonso-García, J. Gran, F. Dékány, I. Minniti, D.

ω Centauri (NGC 5139) contains many variable stars of different types, including the pulsating type II Cepheids, RR Lyrae and SX Phoenicis stars. We carried out a deep, wide-field, near-infrared (IR) variability survey of ω Cen, using the VISTA telescope. We assembled an unprecedented homogeneous...

The VVV Survey RR Lyrae Population in the Galactic Center Region

Autor: Contreras Ramos, R. Minniti, D. Gran, F. Zoccali, M. Alonso-Garcia, J. Huijse, P. Navarro, M.G. Rojas-Arriagada, A. Valenti, E.

Deep near-IR images from the VISTA Variables in the V a L ctea (VVV) Survey were used to search for RR Lyrae stars within 100 arcmin from the Galactic Center. A large sample of 960 RR Lyrae of type ab (RRab) stars were discovered. A catalog is presented featuring the positions, magnitudes, colors...

Proper motions in the VVV Survey: Results for more than 15 million stars across NGC 6544

Autor: Contreras Ramos, R. Zoccali, M. Rojas, F. Rojas-Arriagada, A. Gárate, M. Huijse, P. Gran, F. Soto, M. Valcarce, A.A.R. Estévez, P.A. Minniti, D.

Context. In the last six years, the VISTA Variable in the Vía Láctea (VVV) survey mapped 562 sq. deg. across the bulge and southern disk of the Galaxy. However, a detailed study of these regions, which includes ∼36 globular clusters (GCs) and thousands of open clusters is by no means an easy chal...

Extinction ratios in the inner Galaxy as revealed by the VVV survey

Autor: Alonso-García, J. Minniti, D. Catelan, M. Contreras Ramos, R. Gonzalez, O.A. Hempel, M. Lucas, P.W. Saito, R.K. Valenti, E. Zoccali, M.

Interstellar extinction toward the Galactic Center (GC) is large and significantly differential. Its reddening and dimming effects in red clump (RC) stars in the Galactic Bulge can be exploited to better constrain the extinction law toward the innermost Galaxy. By virtue of a deep and complete ca...

Mapping the outer bulge with RRab stars from the VVV Survey

Autor: Gran, F. Minniti, D. Saito, R. K. Zoccali, M. Gonzalez, O. A. Navarrete, C. Catelan, M. Contreras Ramos, R. Elorrieta, F. Eyheramendy, S. Jordán, A.

Context. The VISTA Variables in the Vía Láctea (VVV) is a near-IR time-domain survey of the Galactic bulge and southern plane. One of the main goals of this survey is to reveal the 3D structure of the Milky Way through their variable stars. In particular, enormous numbers of RR Lyrae stars have b...
