Notes. Columns list the GDR3 ID, spectral type, stellar mass, and the encounter parameters (time, distance, and velocity at pericentre). Values are given as confidence intervals: x50 and [x2.5, x97.5] for x ∈ {t, d, v}, and [0, d95] for extremely close encounters. This table is available in Zenodo. (1)Multiple systems (see Table 3). (2)Reported by Kalas et al. (2001, see our Table 4). (3)This star forms a binary system with GDR3 4078432504018987904.
