Alpha Centauri
Simulates the Alpha Centauri A–B binary: 1.1 and 0.9 solar-mass stars on a 79.9-year, e = 0.52 orbit swinging between 11 and 36 AU, started at apastron.
Scenarios
Nearby multiple-star systems. Alpha Centauri A and B swing between 11 and 36 AU on an 80-year eccentric orbit; Beta Centauri is a hierarchical triple of massive B-type stars.

Simulates Hadar as a hierarchical triple: B-type Aa and Ab (12.0 and 10.6 solar masses) on a 357-day eccentric orbit, with B on a 181-year outer path.
