Another Non-segregated Blue Straggler Population in a Globular Cluster: the Case of NGC 2419
E. Dalessandro, B. Lanzoni, F. R. Ferraro +4
We have used a combination of ACS-HST high-resolution and wide-field SUBARU data in order to study the Blue Straggler Star (BSS) population over the entire extension of the remote…
The Blue Straggler population in the globular cluster M53 (NGC5024): a combined HST, LBT, CFHT study
G. Beccari, B. Lanzoni, F. R. Ferraro +24
We used a proper combination of multiband high-resolution and wide field multi-wavelength observations collected at three different telescopes (HST, LBT and CFHT) to probe Blue Str…
Blue Straggler Stars in the Unusual Globular Cluster NGC 6388
E. Dalessandro, B. Lanzoni, F. R. Ferraro +4
We have used multi-band high resolution HST WFPC2 and ACS observations combined with wide field ground-based observations to study the blue straggler star (BSS) population in the g…
The surprising external upturn of the Blue Straggler radial distribution in M55
B. Lanzoni, E. Dalessandro, S. Perina +4
By combining high-resolution HST and wide-field ground based observations, in ultraviolet and optical bands, we study the Blue Straggler Star (BSS) population of the low density ga…
3-He in the Milky Way Interstellar Medium: Ionization Structure
T. M. Bania, Dana S. Balser, Robert T. Rood +2
The cosmic abundance of the 3-He isotope has important implications for many fields of astrophysics. We are using the 8.665 GHz hyperfine transition of 3-He+ to determine the 3-He/…
A Panchromatic Study of the Globular Cluster NGC 1904. I: The Blue Straggler Population
B. Lanzoni, N. Sanna, F. R. Ferraro +7
By combining high-resolution (HST-WFPC2) and wide-field ground based (2.2m ESO-WFI) and space (GALEX) observations, we have collected a multi-wavelength photometric data base (rang…
