The youngest white dwarf companion to a millisecond pulsar: Insights from NGC 362D
Greta Ettorre, Emanuele Dalessandro, Mario Cadelano +7
We report on the identification of the optical counterpart to the recently discovered millisecond pulsar (MSP) NGC362D in the Galactic globular cluster NGC362 based on deep, multi-…
Fast Rotating Blue Straggler Stars in the globular cluster NGC 1851
Alex Billi, Lorenzo Monaco, Francesco R. Ferraro +4
In this work we study the rotational velocities of a sample of blue straggler stars (BSSs) and reference stars belonging to the Galactic globular cluster NGC 1851, using high-resol…
A candidate to the long sought optical counterpart to the Rapid Burster in the bulge fossil fragment Liller 1
Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni +6
We report on the possible identification of the optical counterpart of the Rapid Burster MXB 1730-335 in the stellar system Liller 1. The identification was performed by taking adv…
Detection of a white dwarf orbiting a Carbon-Oxygen depleted blue straggler in 47 Tucanae
Elisabetta Reggiani, Mario Cadelano, Barbara Lanzoni +3
We have employed deep far-UV observations secured with the Solar Blind Channel of the Advanced Camera for Surveys onboard the Hubble Space Telescope to search for hot companions to…
A binary-related origin mediated by environmental conditions for blue straggler stars
Francesco R. Ferraro, Barbara Lanzoni, Enrico Vesperini +7
Blue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enh…
Rotational velocities of Blue Straggler Stars in the Globular Cluster M55
Alex Billi, Francesco R. Ferraro, Alessio Mucciarelli +3
By using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured radial and rotational velocities of 115 stars in the Galactic globular cluster M55. After…
