A DECam View of the Diffuse Dwarf Galaxy Crater II: Variable Stars
A. Katherina Vivas, Alistair R. Walker, Clara E. Martínez-Vázquez +11
Time series observations of a single dithered field centered on the diffuse dwarf satellite galaxy Crater II were obtained with the Dark Energy Camera (DECam) at the 4m Blanco Tele…
On the use of field RR Lyrae as Galactic probes: I. The Oosterhoff dichotomy based on fundamental variables
M. Fabrizio, G. Bono, V. F. Braga +21
We collected a large data set of field RR Lyrae stars (RRLs) by using catalogues already available in the literature and Gaia DR2. We estimated the iron abundances for a sub-sample…
Chemical Compositions of Field and Globular Cluster RR~Lyrae Stars: II. omega Centauri
D. Magurno, C. Sneden, G. Bono +21
We present a detailed spectroscopic analysis of RR Lyrae (RRL) variables in the globular cluster NGC 5139 (omega Cen). We collected optical (4580-5330 A), high resolution (R = 34,0…
New type II Cepheids from VVV data towards the Galactic center
V. F. Braga, R. Contreras Ramos, D. Minniti +5
The Galactic center (GC) is the densest region of the Milky Way. Variability surveys towards the GC potentially provide the largest number of variable stars per square degree withi…
