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…

VIRAC2: NIR Astrometry and Time Series Photometry for 500M+ Stars from the VVV and VVVX Surveys

Leigh C. Smith, Philip W. Lucas, Sergey E. Koposov +11

We present VIRAC2, a catalogue of positions, proper motions, parallaxes and , , , , and near-infrared photometric time series of 545 346 537 unique stars. The cat…
