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…

MESS: Multi-Epoch Spectroscopic Solver for Detecting Double-Lined Systems
Gil Nachmani, Simchon Faigler, Tsevi Mazeh
We present MESS, a fully automated algorithm for identifying and characterizing double-lined spectroscopic binaries (SB2) in large databases of multi-epoch spectra. MESS extends th…

Revisiting Stellar equatorial rotational velocities with Gaia DR3 line broadening -- the dependence on temperature, mass and age
Amitay Sussholz, Tsevi Mazeh, Simchon Faigler
We used more than Gaia DR3 line broadening vbroad measurements to examine stellar rotation as a function of stellar temperature, mass and age. The large sample clearly displ…
