New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
Variable stars in Terzan 5: additional evidence of multi-age and multi-iron stellar populations
L. Origlia, A. Mucciarelli, G. Fiorentino +8
Terzan 5 is a complex stellar system in the Galactic bulge, harboring stellar populations with very different iron content (Δ[Fe/H] ~1 dex) and with ages differing by several Gyrs.…
unVEil the darknesS of The gAlactic buLgE (VESTALE)
G. Bono, M. Dall'Ora, M. Fabrizio +55
The main aim of this experiment is to provide a complete census of old (t > 10 Gyr, RR Lyrae, type II Cepheids, red horizontal branch), intermediate age (red clump, Miras) and youn…
Massive Star cluster formation under the microscope at z=6
E. Vanzella, F. Calura, M. Meneghetti +12
We report on a superdense star-forming region with an effective radius (R_e) smaller than 13 pc identified at z=6.143 and showing a star-formation rate density Σ_SFR~1000 Msun/yr/k…
Old-Aged Stellar Population Distance Indicators
Rachael L. Beaton, Giuseppe Bono, Vittorio Francesco Braga +8
Old-aged stellar distance indicators are present in all Galactic structures (halo, bulge, disk) and in galaxies of all Hubble types and, thus, are immensely powerful tools for unde…
Variable Stars in Local Group Galaxies. IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
M. Monelli, A. R. Walker, C. E. Martìnez-Vàzquez +9
We present a search and analysis of variable stars in the recently discovered Crater~II dwarf galaxy. Based on , , data collected with the Isaac Newton Telescope (FoV$\si…
