Unveiling the structural content of NGC 6357 via kinematics and NIR variability
C. Ordenes-Huanca, M. Zoccali, A. Bayo +3
NGC 6357, a star-forming complex at kpc from the Sun, contains giant molecular clouds and three prominent star clusters alongside with HII regions, very massive stars an…
New type II Cepheids from VVV data towards the Galactic center
V. F. Braga, R. Contreras Ramos, D. Minniti +5
The Galactic center (GC) is the densest region of the Milky Way. Variability surveys towards the GC potentially provide the largest number of variable stars per square degree withi…
New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
The Unimodal Distribution Of Blue Straggler Stars in M75 (NGC 6864)
R. Contreras Ramos, F. R. Ferraro, E. Dalessandro +2
We have used a combination of multiband high-resolution and wide-field ground-based observations to image the Galactic globular cluster M75 (NGC 6864). The extensive photometric sa…
Pulsation Models for Ultra-Low (Z=0.0004) Metallicity Classical Cepheids
M. Marconi, I. Musella, G. Fiorentino +7
Classical Cepheids are primary distance indicators playing a fundamental role in the calibration of the extragalactic distance scale. The possible dependence of their characteristi…
