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…
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…
On a new method to estimate distance, reddening and metallicity of RR Lyrae stars using optical/near-infrared (,,,,,) mean magnitudes: Centauri as a first test case
G. Bono, G. Iannicola, V. F. Braga +26
We developed a new approach to provide accurate estimates of metal content, reddening and true distance modulus of RR Lyrae stars (RRLs). The method is based on homogeneous optical…
Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data
V. F. Braga, A. Bhardwaj, R. Contreras Ramos +5
Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. We trace t…
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…
On the Impact of Helium Content on the RR Lyrae Distance Scale
M. Marconi, G. Bono, A. Pietrinferni +3
We constructed new sets of He-enhanced (Y = 0.30, Y = 0.40) nonlinear, time-dependent convective hydrodynamical models of RR Lyrae (RRL) stars covering a broad range in metal abund…
