Revisiting the Evidence for Double Sequences of Blue Straggler Stars in Globular Clusters
Gourav Kumawat, Craig O. Heinke, Alison Sills +5
Blue straggler stars (BSSs) are believed to form through mass transfer in binary systems or stellar collisions. The reported presence of double BSS sequences in some globular clust…
Far-ultraviolet investigation into the galactic globular cluster M30 (NGC 7099): II. Potential X-ray counterparts and variable sources
Santana Mansfield, Andrea Dieball, Pavel Kroupa +4
We present a far-ultraviolet (FUV) study of the globular cluster M30 (NGC 7099). The images were obtained using the Advanced Camera for Surveys (ACS/SBC, F150LP, FUV) and the Wide…
Far-ultraviolet investigation into the galactic globular cluster M30 (NGC 7099): I. Photometry and radial distributions
Santana Mansfield, Andrea Dieball, Pavel Kroupa +4
We present a far-ultraviolet (FUV) study of the globular cluster M30 (NGC 7099). The images were obtained using the Advanced Camera for Surveys (ACS/SBC, F150LP, FUV) and the Wide…
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…
Hunting for Brown Dwarfs in the Globular Cluster M4: 2nd epoch HST NIR observations
Andrea Dieball, L. R. Bedin, Christian Knigge +5
We present an analysis of the second epoch HST WFC3 F110W near-Infrared (NIR) imaging data of the globular cluster M4. The new dataset suggests that one of the previously suggested…
Discovery of a double Blue Straggler sequence in M15: new insight into the core-collapse process
Giacomo Beccari, Francesco R. Ferraro, Emanuele Dalessandro +8
In this paper we report on the discovery of a double blue straggler star (BSS) sequence in the core of the core-collapsed cluster M15 (NGC 7078). We performed a detailed photometri…
