Variable stars in the Quintuplet stellar cluster with the VVV survey

Autor: Molina, CN Borissova, J Catelan, M Alonso-Garcia, J Kerins, E Kurtev, R Lucas, PW Medina, N Minniti, D Dekany, I

The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic Centre. We present a new search for variable stars in the vicinity of the cluster, using the five-year data base of the Vista Variables in the Via Lactea (VVV) ESO Public Survey i...

DISCOVERY OF RR LYRAE STARS IN THE NUCLEAR BULGE OF THE MILKY WAY

Autor: Minniti, D Ramos, RC Zoccali, M Rejkuba, M Gonzalez, OA Valenti, E Gran, F

Galactic nuclei, such as that of the Milky Way, are extreme regions with high stellar densities, and in most cases, the hosts of a supermassive black hole. One of the scenarios proposed for the formation of the Galactic nucleus is merging of primordial globular clusters. An implication of this mo...

Heavy elements Ba, La, Ce, Nd, and Eu in 56 Galactic bulge red giants

Autor: Van der Swaelmen, M Barbuy, B Hill, V Zoccali, M Minniti, D Ortolani, S Gomez, A

Aims. The aim of this work is the study of abundances of the heavy elements Ba, La, Ce, Nd, and Eu in 56 bulge giants (red giant branch and red clump) with metallicities ranging from 1 : 3 dex to 0 : 5 dex. Methods. We obtained high-resolution spectra of our giant stars using the FLAMES-UVES sp...

Constraining dust extinction properties via the VVV survey

Autor: Majaess, D Turner, D Dekany, I Minniti, D Gieren, W

Near-infrared color-excess and extinction ratios are essential for establishing the cosmic distance scale and probing the Galaxy, particularly when analyzing targets attenuated by significant dust. A robust determination of those ratios followed from leveraging new infrared observations from the ...

Near-infrared photometry of WISE J085510.74-071442.5

Autor: Osorio, MRZ Lodieu, N Bejar, VJS Martin, EL Ivanov, VD Bayo, A Boffin, HMJ Muzic, K Minniti, D Beamin, JC

Aims. We aim at obtaining near-infrared photometry and deriving the mass, age, temperature, and surface gravity of WISE J085510.74 071442.5 (J0855 0714), which is the coolest object beyond the solar system currently known. Methods. We used publicly available data from the archives of the Hubble...
