RR Lyrae the Stellar Beacons of the Galactic Structure
Giuseppe Bono, Massimo Dall'Ora, Filippina Caputo +5
We present some recent findings concerning the use of RR Lyrae as distance indicators and stellar tracers. We outline pros and cons of field and cluster RR Lyrae stars and discuss…
On a new parameter to estimate the helium content in old stellar systems
F. Troisi, G. Bono, P. B. Stetson +19
We introduce a new parameter Δξ - the difference in magnitude between the red giant branch (RGB) bump and a point on the main sequence (MS) at the same color as the bump, the "benc…
Distance to Galactic globulars using the near-infrared magnitudes of RR Lyrae stars: IV. The case of M5 (NGC5904)
G. Coppola, M. Dall'Ora, V. Ripepi +6
We present new and accurate near-infrared (NIR) J, K-band time series data for the Galactic globular cluster (GC) M5 = NGC5904. Data were collected with SOFI at the NTT (71 J + 120…
Constraints on the Formation of the Globular Cluster IC 4499 from Multi-Wavelength Photometry
A. R. Walker, A. M. Kunder, G. Andreuzzi +9
We present new multiband photometry for the Galactic globular cluster IC 4499 extending well past the main sequence turn-off in the U, B, V, R, I, and DDO51 bands. This photometry…
The Carina Project. IV. radial velocity distribution
M. Fabrizio, M. Nonino, G. Bono +16
We present new and accurate radial velocity (RV) measurements of luminous stars of all ages (old horizontal branch, intermediate--age red clump, and young blue plume, as well as re…
