Automated classification of eclipsing binary systems in the VVV Survey
I. V. Daza-Perilla, L. V. Gramajo, M. Lares +4
With the advent of large-scale photometric surveys of the sky, modern science witnesses the dawn of big data astronomy, where automatic handling and discovery are paramount. In thi…
Raman-scattered O VI features in the symbiotic nova RR Telescopii
Jeong-Eun Heo, Hee-Won Lee, Rodolfo Angeloni +2
RR Tel is an interacting binary system in which a hot white dwarf (WD) accretes matter from a Mira-type variable star via gravitational capture of its stellar wind. This symbiotic…
Variable stars in the VVV globular clusters. II. NGC6441, NGC6569, NGC6626 (M28), NGC6656 (M22), 2MASS-GC02, and Terzan10
Javier Alonso-García, Leigh C. Smith, Márcio Catelan +18
The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. The VVV survey provides a…
A hundred new eclipsing binary system candidates studied in a near-infrared window in the VVV survey
L. V. Gramajo, T. Palma, D. Minniti +4
We present the first results obtained from an extensive study of eclipsing binary (EB) system candidates recently detected in the VISTA Variables in the Vía Láctea (VVV) near-infra…
New Candidate Planetary Nebulae in Galactic Globular Clusters from the VVV Survey
Dante Minniti, Bruno Dias, Matías Gómez +2
Only four globular cluster planetary nebulae (GCPN) are known so far in the Milky Way. About 50 new globular clusters have been recently discovered towards the Galactic bulge. We p…
CCD Washington photometry of 10 open clusters or candidates projected close to the Galactic plane
Juan J. Clariá, M. Celeste Parisi, Tali Palma +2
We present high-quality CCD photometry in the Washington system C and T1 passbands down to T1 ~ 19.5 mag in the fields of 10 Galactic open clusters (OCs) or candidates projected cl…
