Blanco 1 is an ≈130 Myr open cluster located 240 pc from the Sun, below the Galactic plane. Recent studies have reported the existence of diffuse tidal tails extending 50–60 pc from the cluster center based on the positions and velocities measured by Gaia. To independently assess the reality and extent of this structure, we used light curves generated from TESS full-frame images to search for photometric rotation periods of stars in and around Blanco 1. We detected rotation periods down to a stellar effective temperature of ≈3100 K in 347 of the 603 cluster member candidates for which we have light curves. For cluster members in the core and candidate members in the tidal tails, both within a temperature range of 4400–6200 K, 74% and 72% of the rotation periods, respectively, are consistent with the single-star gyrochronological sequence. In contrast, a comparison sample of field stars yielded gyrochrone-consistent rotation periods for only 8.5% of the stars. The tidal tail candidates’ overall conformance to the core members’ gyrochrone sequence implies that their contamination ratio is consistent with zero and |
