Infrared variability of young solar analogs in the Lagoon Nebula
C. Ordenes-Huanca, M. Zoccali, A. Bayo +9
T Tauri stars are low-mass pre-main sequence stars that are intrinsically variable. Due to the intense magnetic fields they possess, they develop dark spots on their surface that,…
Spectroscopic analysis of VVV CL001 cluster with MUSE
Julio Olivares Carvajal, Manuela Zoccali, Alvaro Rojas-Arriagada +4
Like most spiral galaxies, the Milky Way contains a population of blue, metal-poor globular clusters and another of red, metal-rich ones. Most of the latter belong to the bulge, an…
The VVV survey: Long-period variable stars I. Photometric catalog of ten VVV/OGLE tiles
F. Nikzat, C. E. Ferreira Lopes, M. Catelan +7
Long-period variable stars (LPVs) are pulsating red giants, primarily in the asymptotic giant branch phase, and they include both Miras and semi-regular variables (SRVs). Their per…
Hidden in the Haystack: Low-luminosity globular clusters towards the Milky Way bulge
F. Gran, M. Zoccali, I. Saviane +8
Recent wide-area surveys have enabled us to study the Milky Way with unprecedented detail. Its inner regions, hidden behind dust and gas, have been partially unveiled with the arri…
CAPOS: The bulge Cluster APOgee Survey I. Overview and initial ASPCAP results
Doug Geisler, Sandro Villanova, Julia E. O'Connell +39
Context. Bulge globular clusters (BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational d…
Variable stars in the VVV globular clusters. II. NGC6441, NGC6569, NGC6626 (M28), NGC6656 (M22), 2MASS-GC02, and Terzan10
Javier Alonso-García, Leigh C. Smith, Márcio Catelan +18
The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. The VVV survey provides a…
