The Potential of Exozodiacal Disks Observations with the WFIRST Coronagraph Instrument
B. Mennesson, V. Bailey, J. Kasdin +60
The Wide Field Infrared Survey Telescope (WFIRST) Coronagraph Instrument (CGI) will be the first high-performance stellar coronagraph using active wavefront control for deep starli…
Galactic globular clusters: a new catalog of masses, structural parameters, velocity dispersion profiles, proper motions and space orbits
Michael Hilker, Holger Baumgardt, Antonio Sollima +1
We collected radial velocities of more than 50.000 individual stars in 156 Galactic globular clusters (GGC) and matched them with HST photometry and Gaia DR2 proper motions. This a…
Imprints of Evolution on the Internal Kinematics of Globular Clusters
Laura L. Watkins, Roeland P. van der Marel, Andrea Bellini +2
Globular clusters are collisional systems, meaning that the stars inside them interact on timescales much shorter than the age of the Universe. These frequent interactions transfer…
The HST Large Programme on NGC 6752. III. Detection of the Peak of the White Dwarf Luminosity Function
L. R. Bedin, M. Salaris, J. Anderson +10
We report on the white dwarf cooling sequence of the old globular cluster NGC 6752, which is chemically complex and hosts a blue horizontal branch. This is one of the last globular…
On the photometric signature of fast rotators
Léo Girardi, Guglielmo Costa, Yang Chen +4
Rapidly rotating stars have been recently recognized as having a major role in the interpretation of colour-magnitude diagrams of young and intermediate-age star clusters in the Ma…
Spectral Energy Distribution of Blue Stragglers in the core of 47 Tucanae
S. Raso, C. Pallanca, F. R. Ferraro +8
We have constructed the Spectral Energy Distributions (SEDs) of a sample of Blue Straggler Stars (BSSs) in the core of the globular cluster 47 Tucanae, taking advantage of the larg…
