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…

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

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…
Protostars at Subsolar Metallicity: First Detection of Large Solid-state Complex Organic Molecules in the Large Magellanic Cloud
Marta Sewiło, Will R. M. Rocha, Martijn van Gelder +11
We present the results of James Webb Space Telescope observations of the protostar ST6 in the Large Magellanic Cloud (LMC) with the Medium Resolution Spectrograph of the Mid-Infrar…
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…
PROJECT-J: JWST observations of HH46~IRS and its outflow. Overview and first results
B. Nisini, M. G. Navarro, T. Giannini +23
We present the first results of the JWST program PROJECT-J (PROtostellar JEts Cradle Tested with JWST ), designed to study the Class I source HH46 IRS and its outflow through NIRSp…
The globular cluster VVV CL002 falling down to the hazardous Galactic centre
D. Minniti, N. Matsunaga, J. G. Fernandez-Trincado +15
Context. The Galactic centre is hazardous for stellar clusters because of the strong tidal force. Supposedly, many clusters were destroyed and contributed stars to the crowded stel…
Globular Clusters in the Galactic Center Region: expected behavior in the infalling and merger scenario
Maria Gabriela Navarro, Roberto Capuzzo-Dolcetta, Manuel Arca-Sedda +1
The infall and merger scenario of massive clusters in the Milky Way's potential well, as one of the Milky Way formation mechanisms, is reexamined to understand how the stars of the…
Unveiling short period binaries in the inner VVV bulge
E. Botan, R. K. Saito, D. Minniti +5
Most of our knowledge about the structure of the Milky Way has come from the study of variable stars. Among the variables, mimicking the periodic variation of pulsating stars, are…

Maria Gabriela Navarro, Dante Minniti, Roberto Capuzzo-Dolcetta +4
The projected density distribution of type ab RR Lyrae (RRab) stars was characterised from the innermost regions of the Milky Way to the halo, with the aim of placing constraints o…
VVV survey microlensing: candidate events with source in the far disk
