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…

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…

Young Stellar Objects in the Carina nebula: Near-Infrared variability and spectroscopy

Jura Borissova, Radostin Kurtev, Josemanuel Escobar +10

We present a catalog of 652 young stellar objects (YSOs) in the Carina star-forming region. The catalog was constructed by combining near-infrared Ks-band variability from the VIST…

The VVV near-IR galaxy catalogue of the southern Galactic disc

M. V. Alonso, L. D. Baravalle, J. L. Nilo Castellón +16

The distribution of galaxies in the Zone of Avoidance (ZoA) is incomplete due to the presence of our own Galaxy. Our research focused on the identification and characterisation of…

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…
