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…

High-Precision Near-Infrared Abundances of Solar Analogs in the YJ Bands

Noriyuki Matsunaga, Takuji Tsujimoto, Daisuke Taniguchi +12

We present a near-infrared abundance analysis of 46 solar analogs with known ages, observed with the WINERED WIDE-mode spectrograph at a resolution of . Using an empi…

Kinematical and dynamical properties of recently discovered bulge and disc star clusters with WINERED

Ilaria Petralia, Dante Minniti, José G. Fernández-Trincado +8

Context. Galactic globular clusters are a very important tool in explaining the characteristics of the Milky Way. Therefore it is essential to determine the kinematical and dynamic…

The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy

R. K. Saito, M. Hempel, J. Alonso-García +143

The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…

Signature of systemic rotation in 21 Galactic Globular Clusters from APOGEE-2

Ilaria Petralia, Dante Minniti, José G. Fernández-Trincado +2

Context. Traditionally, Globular Clusters (GCs) have been assumed to be quasi-relaxed non-rotating systems, characterized by spherical symmetry and orbital isotropy. However, in re…

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…
