SPICY 30021: an embedded bona fide FUor with a mid-infrared precursor
Zhen Guo, Calum Morris, Vitor Fermiano +37
Unstable mass accretion in young stellar objects (YSOs) often leads to observable outbursts, which play a key role in stellar mass assembly during pre-main-sequence evolution. The…
Unresolved triples in the open cluster NGC 2437 (M 46) confirmed by the KMOS VVVX-GalCen Spectroscopic Survey
D. Minniti, T. Palma, C. O. Obasi +31
Recent optical and near-IR photometric databases like Gaia data release 3 (DR3) and the VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey allow the exploration of…
A Newly Discovered VVVX Star Cluster Surfing the Galactic Disk
Elisa R. Garro, José G. Fernández-Trincado, Casmir O. Obasi +15
We report the discovery of Garro 04, a previously unidentified stellar cluster toward the Galactic disc, uncovered as part of the ESO/KMOS VVVX-GalCen Spectroscopic Survey. This ob…
Unresolved triple systems in the aged open cluster Trumpler 19: Discovery, confirmation, and implications
D. Minniti, R. K. Saito, V. D. Ivanov +31
It is difficult to identify unresolved triple and higher-order systems beyond the solar vicinity. Star clusters yield controlled environments with known physical parameters, provid…
Consensus based Algorithm for Nonparametric Detection of Star Clusters (CANDiSC)
C O Obasi, J G Fernandez Trincado, M Gomez +14
Context: The VISTA Variables in the Via Lactea (VVV) and its extension (VVVX) are near-infrared surveys mapping the Galactic bulge and adjacent disk. These data have enabled the di…
VVV-WIT-13: an eruptive young star with cool molecular features
Zhen Guo, Philip Lucas, Sergey N. Yurchenko +27
Here we investigate an infrared eruptive source, identified from the decade-long VISTA Variables in the Via Lactea survey (VVV). We named this target after a group of variable sour…
A Benchmark White Dwarf-Ultracool Dwarf Wide Field Binary
Thiago Ferreira, Roberto K. Saito, Dante Minniti +8
We present the discovery and multi-wavelength characterisation of VVV J1438-6158 AB, a new field wide-binary system consisting of a 4.6(+5.5-2.4) Gyr and Teff = 9500+/-125 K DA whi…
M-dwarf stars in the b294 field from the VISTA Variables in the Vía Láctea (VVV)
Patricia Cruz, Miriam Cortés-Contreras, Enrique Solano +4
M-dwarf stars are the dominant stellar population in the MilkyWay and they are important for a wide variety of astrophysical topics. The Gaia mission has delivered a superb collect…
The globular cluster system of the nearest Seyfert II galaxy Circinus
C. Obasi, M. Gómez, D. Minniti +7
Context. The globular cluster (GC) system of Circinus galaxy has not been probed previously partly because of the location of the galaxy at - 3.8 Galactic latitude which su…
VVV WIN 17333349: a low extinction window to probe the far side of the Milky Way bulge
Roberto K. Saito, Dante Minniti, Robert A. Benjamin +5
Windows of low extinction in the Milky Way (MW) have been used along the past decades for the study of the Galactic structure and the stellar population across the inner bulge and…
Variable stars in the globular cluster M28 (NGC 6626)
G. Prieto, M. Catelan, R. Contreras Ramos +3
We present a new search for variable stars in the Galactic globular cluster M28 (NGC 6626). The search is based on a series of BVI images obtained with the SMARTS Consortium's 1.3m…
Variability and stellar populations with deep optical-IR images of the Milky Way disk: matching VVV with VLT/VIMOS data
P. Pietrukowicz, D. Minniti, J. Alonso-Garcia +1
We have used deep V-band and JHKs-band observations to investigate variability and stellar populations near the Galactic plane in Centaurus, and compared the observations with the…
New Galactic Star Clusters Discovered in the VVV Survey
Jura Borissova, Charles Bonatto, Radostin Kurtev +27
VISTA Variables in the V\'ıa Láctea (VVV) is one of the six ESO Public Surveys operating on the new 4-meter Visible and Infrared Survey Telescope for Astronomy (VISTA). VVV is scan…
