Variable stars in the Quintuplet stellar cluster with the VVV survey
(OXFORD UNIV PRESS, 2016-10)
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 ...
Heavy elements Ba, La, Ce, Nd, and Eu in 56 Galactic bulge red giants
(EDP SCIENCES, 2016-02)
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. ...
Constraining dust extinction properties via the VVV survey
(EDP SCIENCES, 2016-09)
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 ...
Near-infrared photometry of WISE J085510.74-071442.5
(EDP SCIENCES, 2016-08)
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. ...
DISCOVERY OF RR LYRAE STARS IN THE NUCLEAR BULGE OF THE MILKY WAY
(IOP PUBLISHING, 2016-10)
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 ...
