Weak Galactic halo--dwarf spheroidal connection from RR Lyrae stars

Giuliana Fiorentino, Giuseppe Bono, Matteo Monelli +6

We discuss the role that dwarf galaxies may have played in the formation of the Galactic halo (Halo) using RR Lyrae stars (RRL) as tracers of their ancient stellar component. The c…

A stellar population synthesis approach to the Oosterhoff dichotomy

A. Sollima, S. Cassisi, G. Fiorentino +1

We use color-magnitude diagram synthesis together with theoretical relations from non-linear pulsation models to approach the long-standing problem of the Oosterhoff dichotomy rela…

On the use of asymmetric PSF on NIR images of crowded stellar fields

Giuliana Fiorentino, Ivan Ferraro, Giacinto Iannicola +8

We present data collected using the camera PISCES coupled with the Firt Light Adaptive Optics (FLAO) mounted at the Large Binocular Telescope (LBT). The images were collected using…

Homogeneous Photometry VI: Variable Stars in the Leo I Dwarf Spheroidal Galaxy

Peter B. Stetson, Giuliana Fiorentino, Giuseppe Bono +5

We have characterized the pulsation properties of 164 candidate RR Lyrae variables (RRLs) and 55 candidate Anomalous and/or short-period Cepheids in Leo I dwarf spheroidal galaxy.…

Constraining the true nature of an exotic binary in the core of NGC 6624

E. Dalessandro, C. Pallanca, F. R. Ferraro +4

We report on the identification of the optical counterpart to Star1, the exotic object serendipitously discovered by Deutsch et al. in the core of the Galactic globular cluster NGC…
