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…
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…
The Gaia parallax discrepancy for the cluster Pismis 19, and separating Scutis from Cepheids
Daniel Majaess, Charles J. Bonatto, David G. Turner +10
Pre-Gaia distances for the open cluster Pismis 19 disagree with Gaia parallaxes. A 2MASS red clump distance was therefore established for Pismis 19 ( kpc), whic…
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…
