VVV Survey Microlensing Events in the Galactic Center Region
María Gabriela Navarro, Dante Minniti, Rodrigo Contreras Ramos
We search for microlensing events in the highly reddened areas surrounding the Galactic center using the near-IR observations with the VISTA Variables in the Vía Láctea Survey (VVV…
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)…
