Cepheids with giant companions III. Evolutionary modeling of nine binary double Cepheids from the Milky Way and Magellanic Clouds
F. Espinoza-Arancibia, B. Pilecki, M. Catelan +3
Binary double (BIND) Cepheids are systems comprising two Cepheid components. This feature provides important constraints that allow us to reveal the origin of Cepheids, trace their…
A near-infrared stellar atlas of the Galactic plane from the VVVX survey
Javier Alonso-García, Maren Hempel, Roberto K. Saito +12
The VISTA Variables in the Via Lactea eXtended (VVVX) ESO public survey observed the Galactic plane and the outer Galactic bulge in the near-infrared to mitigate the effects of ext…
RR Lyrae stars with variable mean magnitudes
Gergely Hajdu, Johanna Jurcsik, Márcio Catelan +6
Context. A number of RR Lyrae stars show variable mean magnitudes in the OGLE survey light curves of the Galactic bulge. Hitherto this phenomenon was not studied, as it was general…
Variable stars in the VVV globular clusters III. RR Lyrae stars in the inner Galactic globular clusters
Javier Alonso-García, Leigh C. Smith, Jason L. Sanders +13
High reddening near the Galactic plane hampers observations and proper characterization of the globular clusters (GCs) located toward the inner regions of the Milky Way. The VISTA…
Near-IR period-luminosity relations for pulsating stars in Centauri (NGC 5139)
C. Navarrete, M. Catelan, R. Contreras Ramos +4
Centauri (NGC 5139) hosts hundreds of pulsating variable stars of different types, thus representing a treasure trove for studies of their corresponding period-luminosity (PL)…
An Updated Census of RR~Lyrae Stars in the Globular Cluster ~Centauri (NGC\,5139)
C. Navarrete, R. Contreras Ramos, M. Catelan +7
[ABRIDGED] Centauri (NGC 5139) contains large numbers of variable stars of different types and, in particular, more than a hundred RR Lyrae stars. We have conducted a variabili…
Orbital and physical parameters of eclipsing binaries from the All-Sky Automated Survey catalogue - VII. V1200 Centauri: a bright triple in the Hyades moving group
J. Coronado, K. G. Hełminiak, L. Vanzi +6
We present the orbital and physical parameters of the detached eclipsing binary V1200~Centauri (ASAS~J135218-3837.3) from the analysis of spectroscopic observations and light curve…
Massive open star clusters using the VVV survey III: A young massive cluster at the far edge of the Galactic bar
S. Ramírez Alegría, J. Borissova, A. N. Chené +14
Context: Young massive clusters are key to map the Milky Way's structure, and near-IR large area sky surveys have contributed strongly to the discovery of new obscured massive stel…
Three Galactic globular cluster candidates
C. Moni Bidin, F. Mauro, D. Geisler +12
The census of Galactic globular clusters (GCs) is still incomplete, and about ten new objects are supposed to await discovery, hidden behind the crowded and reddened regions of the…
