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…
The deepest color-magnitude diagrams for the benchmark open cluster NGC 2437 from Gaia and VVVX
Tali Palma, Matías Gómez, Dante Minniti +8
Deep photometry of Galactic star clusters provides one of the most powerful tools for determining their physical properties. In particular, in low Galactic latitude regions that su…
Ultracool and Brown Dwarf Candidates Identified via CatWISE-2MASS-Gaia DR3
Daniel Majaess, Dante Minniti, Matias Gomez +2
Ultracool and brown dwarf candidates ( pc, ) were identified via multiband and astrometric data from CatWISE (), 2MASS (), and…
The potential broader complex linked to the key Cepheid SV Vul
Daniel Majaess, Ignacio Negueruela, Leonid N. Berdnikov +10
A new distance was established to the Cepheid SV Vul () and its host cluster Alicante 13, and is tied in part to deeper UKIDSS-DR6 photometry and Gaia DR3 observatio…
