Exoplanets in ancient stellar populations: occurrence constraints and hot-Jupiter candidates in the Galactic halo
Dolev Bashi, Michelle Kunimoto, Kevin K. Hardegree-Ullman +3
The Galactic halo preserves a record of the Milky Way's earliest assembly and contains both in-situ stars and stars accreted from dwarf galaxies. Possible planets around these star…
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…
Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, A. Gómez, E. Caffau +39
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…
Do Outer Giants Inflate Neptune-sized Planets? An Architecture-Dependent Mass-Radius Relation
Dolev Bashi
Exoplanet demographics increasingly reveal that planetary properties depend not only on local irradiation and composition but also on the wider system architecture. We analyse a sa…
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…
Searching for compact hierarchical triple systems candidates in astrometric binaries and accelerated solutions
Dolev Bashi, Andrei Tokovinin
Compact hierarchical triple (CHT) systems, where a tertiary component orbits an inner binary, provide critical insights into stellar formation and evolution. Despite their importan…
