Joint radial-velocity and astrometry analysis detects five new cold giant planets and improves precision on two known ones around CHEPS targets.
Reports a close stellar encounter rate of 10.6 ± 4.5 per Myr per star within 1 pc for stars in the solar neighborhood, with the GJ 710 approach being rarer than average at one per ~50 Myr.
