Proper motions in the VVV Survey: Results for more than 15 million stars across NGC 6544
R. Contreras Ramos, M. Zoccali, F. Rojas +8
Context: In the last six years, the VVV survey mapped 562 sq. deg. across the bulge and southern disk of the Galaxy. However, a detailed study of these regions, which includes $\si…
Pulsating stars in Centauri: Near-IR properties and period-luminosity relations
Camila Navarrete, Márcio Catelan, Rodrigo Contreras Ramos +4
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-fiel…
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)…
FSR 1716: A new Milky Way Globular Cluster confirmed using VVV RR Lyrae stars
Dante Minniti, Tali Palma, Istvan Dékány +35
We use deep multi-epoch near-IR images of the VISTA Variables in the Vía Láctea (VVV) Survey to search for RR Lyrae stars towards the Southern Galactic plane. Here we report the di…
