The VELOCE modulation zoo III. Detecting additional pulsation modes in optical spectra of classical Cepheids using semi-partial distance correlation periodograms
Kent Barbey, Richard Irving Anderson, Giordano Viviani +5
Known for their large amplitude radial pulsations, classical Cepheids are critical standard candles in astrophysics. However, they also exhibit various pulsational irregularities a…

A generative model for Gaia astrometric orbit catalogs: selection functions for binary stars, giant planets, and compact object companions
Kareem El-Badry, Casey Lam, Berry Holl +4
Astrometry from Gaia DR3 has produced a sample of 170,000 Keplerian orbital solutions, with many more anticipated in the next few years. These data have enormous potential to…
