Asteroseismic binaries likely to be gravitationally bound systems. Colours represent the method used to detect the binarity, where yellow, green, and light blue represent wide binaries (Table 1), stars with high RUWE (Table 2), and stars with RV variability indicators (Table 3), respectively. Circles represent ABs for which both solar-like oscillators were matched to a Gaia source (Table D.1). Squares depict ABs for which only one of the two oscillators was matched (Table D.2), and triangles correspond to ABs for which none of the oscillators was matched to a Gaia source (Table D.3). Black lines show Dartmouth evolutionary tracks (Dotter et al. 2008) for 0.8−2.6 M_⊙ at solar metallicity, with mass decreasing from left to right.
