"WebJan 12, 2024 · Binary stars are ubiquitous: more than half the stars with masses of 1 M⊙ or higher are found in binary or multiple systems (Raghavan et al. 2010; Sana' et al. 2012; Moe & Di Stefano 2024 ). Binaries are thus a natural product of star formation and make up a large fraction of the visible universe. " - Binary star light curve
