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…
Hot water emission during an outburst in a classical T Tauri star
Zhen Guo, Javier Osses, Vitor Fermiano +34
In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…
High energy gamma-ray sources in the VVV survey - III. Spectroscopic confirmation of an AGN at low Galactic latitudes
Eduardo O. Schmidt, Laura D. Baravalle, Ana Pichel +9
We aim to spectroscopically confirm the nature of VVV-J181258.71-314346.7, a candidate counterpart to the unassociated gamma-ray source 4FGLJ1812.8-3144. This object was selected b…
Obscured star clusters in the Inner Milky Way. How many massive young clusters are still awaiting detection?
Akash Gupta, Valentin D. Ivanov, Thomas Preibisch +1
Aims. Our goal is twofold. First, to detect new clusters we apply the newest methods for the detection of clustering with the best available wide-field sky surveys in the mid-infra…
Accretion Funnel Reconfiguration during an Outburst in a Young Stellar Object: EX Lupi
Koshvendra Singh, Joe P. Ninan, Marina M. Romanova +14
EX Lupi, a low-mass young stellar object, went into an accretion-driven outburst in March of 2022. The outburst caused a sudden phase change of ~ 112 5 in…
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…
Searching for Faint Comoving Companions to the Centauri system in the VVV Survey Infrared Images
J. C. Beamin, D. Minniti, J. B. Pullen +7
The VVV survey has observed the southern disk of the Milky Way in the near infrared, covering 240 deg in the filters. We search the VVV Survey images in a 19…
VVV High proper motion stars I. The catalogue of bright Ks < 13.5 stars
R. Kurtev, M. Gromadzki, J. C. Beamin +14
Knowledge of the stellar content near the Sun is important for a broad range of topics ranging from the search for planets to the study of Milky Way structure. The most powerful me…
Discovery of a brown dwarf companion to the A3V star β Circini
L. C. Smith, P. W. Lucas, C. Contreras Peña +14
We report the discovery of an L dwarf companion to the A3V star β Circini. VVV J151721.49-585131.5, or β Cir B, was identified in a proper motion and parallax catalogue of the Vist…
Spectro-photometric characterization of high proper motion sources from WISE
J. C. Beamín, V. D. Ivanov, D. Minniti +7
The census of the solar neighborhood is almost complete for stars and becoming more complete in the brown dwarf regime. Spectroscopic, photometric and kinematic characterization of…
Proper motions and brown dwarfs with the VVV survey
J. C. Beamín, V. D. Valentin, R. Kurtev +3
The Vista Variables in the Vía Láctea survey (VVV) is a near-IR ESO public survey devoted to study the Galactic bulge and southern inner disk covering 560 deg on the sky. This…
Young Massive Clusters/Associations in the GMC G23.3-0.3
M. Messineo, K. M. Menten, D. Figer +7
An overview of a spectroscopic survey for massive stars in the direction of the Galactic giant molecular complex G23.3-0.3 is presented (Messineo et al. 2010, and 2014 A&A submitte…
VVV High Proper Motion Survey
M. Gromadzki, R. Kurtev, S. Folkes +7
Here we present survey of proper motion stars towards the Galactic Bulge and an adjacent plane region base on VISTA-VVV data. The searching method based on cross-matching photometr…
