Unbound Close Stellar Encounters in the Solar Neighborhood

We present a catalog of unbound stellar pairs, within 100 pc the Sun, that are undergoing close, hyperbolic, encounters. The data drawn from GAIA EDR3 catalogue, and limiting factors errors in radial distance unknown velocities along line sight. Such pairs have been suggested (Hansen & Zuckerman 2021) to be possible events associated with migration technological civilisations between stars. As such, this sample may represent finite set targets for SETI search based on hypothesis. Our contains total 132 close passage events, featuring stars across entire main sequence, 16 at least one sequence star spectral type K1 F3. Many these also binaries, so we isolate eight single as most likely candidates an ongoing event -- HD 87978, 92577, 50669, 44006, 80790, LSPM J2126+5338, J0646+1829 192486. Amongst host known planets, GJ 433 HR 858 best candidates.
