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…

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…

A near-infrared stellar atlas of the Galactic plane from the VVVX survey

Javier Alonso-García, Maren Hempel, Roberto K. Saito +12

The VISTA Variables in the Via Lactea eXtended (VVVX) ESO public survey observed the Galactic plane and the outer Galactic bulge in the near-infrared to mitigate the effects of ext…

Spectroscopic follow-up of Gaia alerted Young Stellar Object variables: the Large Binocular Telescope view

Teresa Giannini, Manuele Gangi, Fernando Cruz-Saenz de Miera +13

We analyzed optical/near-IR Large Binocular Telescope spectra of 16 sources alerted by Gaia between 2021 and 2024 due to significant photometric variability. Half of the spectra we…
