Red dwarf stars, which represent 75% of stars in the Milky Way, can be studied in great detail in the solar neighborhood where the sample is more complete. We intend to better char…
Confirmation Of Two New Galactic Bulge Globular Clusters: FSR 19 and FSR 25
Casmir Obasi, Matias Gomez, Dante Minniti +1
Globular clusters (GCs) in the Milky Way (MW) bulge are very difficult to study because: i) they suffer from the severe crowding and galactic extinction; which are characteristic o…

The RR Lyrae projected density distribution from the Galactic centre to the halo
Maria Gabriela Navarro, Dante Minniti, Roberto Capuzzo-Dolcetta +4
The projected density distribution of type ab RR Lyrae (RRab) stars was characterised from the innermost regions of the Milky Way to the halo, with the aim of placing constraints o…
The VVV Infrared Variability Catalog (VIVA-I)

Thanks to the VISTA Variables in the Via Lactea (VVV) ESO Public Survey it is now possible to explore a large number of objects in those regions. This paper addresses the variabili…
Candidate Hypervelocity Red Clump Stars in the Galactic Bulge Found Using the VVV and Gaia Surveys
Alonso Luna, Dante Minniti, Javier Alonso-García
We propose a new way to search for hypervelocity stars in the Galactic bulge, by using red clump (RC) giants, that are good distance indicators. The 2nd Gaia Data Release and the n…
Short and long term near-infrared spectroscopic variability of eruptive protostars from VVV
Zhen Guo, P. W. Lucas, C. Contreras Peña +7
Numerous eruptive variable young stellar objects (YSOs), mostly Class I systems, were recently detected by the near-infrared Vista Variables in the Via Lactea (VVV) survey. We pres…
