A Quadruple Excess in Wide Binary Systems: Evidence for Correlated Binary Formation
Dolev Bashi, Cathie J. Clarke, Vasily Belokurov
Understanding the multiplicity of stellar systems and the correlations between their hierarchical components provides crucial insights into star formation processes. If binary comp…
Hide and Seek with Gaia. Detectability of Predicted Thin-Disc Metal-Rich RR Lyrae Binaries in Gaia DR3 and DR4
Giuliano Iorio, Pranav Nagarajan, Alexey Bobrick +8
RR Lyrae stars (RRLs) are classical tracers of old stellar populations, yet growing evidence suggests the presence of a metal-rich ([Fe/H]>-0.5), intermediate-age (2-7 Gyr) sub-pop…
Fewer Companions in the Crowd: The Low Close Binary Fraction in Globular Clusters from Gaia RVS
Dolev Bashi, Vasily Belokurov
In dense environments like globular clusters (GCs), dynamical interactions can disrupt or harden close binaries, nonetheless, detailed comparisons with field binary fractions remai…
Revealing the ages of metal-rich RR Lyrae via kinematic label transfer
HanYuan Zhang, Giuliano Iorio, Vasily Belokurov +3
RR Lyrae stars have long been considered reliable tracers of old, metal-poor populations, primarily due to their prevalence in globular clusters and the Galactic halo. However, the…
Predicting metallicities and carbon abundances from Gaia XP spectra for (carbon-enhanced) metal-poor stars
Anke Ardern-Arentsen, Sarah G. Kane, Vasily Belokurov +4
Carbon-rich (C-rich) stars can be found at all metallicities and evolutionary stages. They are often the result of mass-transfer from a companion, but some of the most metal-poor C…
