ESO User Support and Observation Preparation for VLTI Science Operations
M. Wittkowski, G. Beccari, A. Corporaal +15
The paper describes recent user‑focused upgrades to the VLTI, including new guiding and instrument modes, enhanced observation‑planning tools, and the availability of reduced GRAVI…
Binary stars as dynamical tracers in globular clusters .II. Evolution of the radial distribution of the binary star fraction
J. Bruce, E. Vesperini, E. Dalessandro +5
The distinct dynamical environments occupied by multiple stellar populations in globular clusters play a significant role in many aspects of cluster evolution, including the dynami…
Binary Stars as Dynamical Tracers in Globular Clusters .I. First Observations of Bimodal Spatial Distributions
M. Cadelano, E. Dalessandro, J. Bruce +7
We present the first homogeneous study of the radial distribution of the binary fraction across the full extent of six Galactic globular clusters (GCs) spanning a wide range of dyn…
Far-ultraviolet flux distribution in Orion and its relation to stellar accretion
Rossella Anania, Andrew J. Winter, Miguel Vioque +8
Orion is the closest region hosting active star formation and young OBA stars. Computing far-ultraviolet (FUV) fluxes at its stars is essential to connect stellar and protoplanetar…
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…
RGB Tip distance to the faint gas-rich dwarf KK 153
M. Bellazzini, G. Beccari, R. Pascale +4
KK 153 is a star-forming dwarf galaxy that has been recently proposed as a new member of the sparsely populated class of gas-rich ultra faint dwarfs, lying in the outskirts of the…
