Planetary Nebula Central Stars as Tracers of Planetary Nebula-Star Cluster Associations in the Galaxy

Vasiliki Fragkou, Luis Lomelí-Núñez, Dante Minniti +2

Planetary nebulae (PNe) that are physically associated with star clusters are rare but crucial for stellar evolution studies because they allow their initial and final stellar prop…

Near-infrared photometry of the central stars of planetary nebulae with the VVVX survey

Dante Minniti, Vasiliki Fragkou, Javier Alonso-García +2

Achieving accurate photometric characterizations of central stars of planetary nebulae (CSPNe) toward the galactic plane is significantly hindered by the high levels of interstella…

VVV-WIT-13: an eruptive young star with cool molecular features

Zhen Guo, Philip Lucas, Sergey N. Yurchenko +27

Here we investigate an infrared eruptive source, identified from the decade-long VISTA Variables in the Via Lactea survey (VVV). We named this target after a group of variable sour…

Revealing the Origins of Galactic Globular Clusters via Their Mg-Al Abundances

Shihui Lin, Baitian Tang, Genghao Liu +4

Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifyin…

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…

Variable stars in the VVV globular clusters III. RR Lyrae stars in the inner Galactic globular clusters

Javier Alonso-García, Leigh C. Smith, Jason L. Sanders +13

High reddening near the Galactic plane hampers observations and proper characterization of the globular clusters (GCs) located toward the inner regions of the Milky Way. The VISTA…

The Valuable Long-period Cluster Cepheid KQ Scorpii and other Calibration Candidates

Daniel Majaess, David G. Turner, Dante Minniti +2

The classical Cepheid KQ Sco is a valuable anchor for the distance scale because of its long pulsation period () and evidence implying membership in the open cluster…

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…

High-precision astrometry with VVV -- II. A near-infrared extension of Gaia into the Galactic plane

M. Griggio, M. Libralato, A. Bellini +4

Aims. We use near-infrared, ground-based data from the VISTA Variables in the Via Lactea (VVV) survey to indirectly extend the astrometry provided by the Gaia catalog to objects in…

High energy gamma-ray sources in the VVV survey -- II. The AGN counterparts

Laura G. Donoso, Ana Pichel, Laura D. Baravalle +9

We identified Active Galactic Nuclei (AGN) candidates as counterparts to unidentified gamma-ray sources (UGS) from the Fermi-LAT Fourth Source Catalogue at lower Galactic latitudes…

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…
