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…

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…

Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey

J. V. Sales-Silva, K. Cunha, V. V. Smith +20

The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…

Spatial Property of Multiple Metallic Populations in the Tidal Stream of ω Centauri

Shiru Zheng, Baitian Tang, Long Wang +4

ω Centauri, the remnant nucleus of an accreted dwarf galaxy, is a unique laboratory for studying complex stellar populations. The recently discovered Fimbulthul stream provides a f…

Consensus based Algorithm for Nonparametric Detection of Star Clusters (CANDiSC)

C O Obasi, J G Fernandez Trincado, M Gomez +14

Context: The VISTA Variables in the Via Lactea (VVV) and its extension (VVVX) are near-infrared surveys mapping the Galactic bulge and adjacent disk. These data have enabled the di…
