VELOcities of CEpheids (VELOCE) II. Systematic Search for Spectroscopic Binary Cepheids
Shreeya S. Shetye, Giordano Viviani, Richard I. Anderson +4
Classical Cepheids provide valuable insights into the evolution of stellar multiplicity among intermediate-mass stars. Here, we present a systematic investigation of single-lined s…
VELOcities of CEpheids (VELOCE) I. High-precision radial velocities of Cepheids
Richard I. Anderson, Giordano Viviani, Shreeya S. Shetye +27
This first VELOCE data release comprises 18,225 high-precision RV measurements of 258 bona fide classical Cepheids on both hemispheres collected mainly between 2010 and 2022, along…
The 33 M black hole Gaia BH3 is part of the disrupted ED-2 star cluster
E. Balbinot, E. Dodd, T. Matsuno +19
The Gaia Collaboration has recently reported the detection of a 33 M black hole in a wide binary system located in the Solar neighbourhood. Here we explore the relationship…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
