Extended Data Table 1 Possible orbital solutions for the W Aql system

From: Chemical tracers of a highly eccentric AGB–main-sequence star binary

  1. Table notes: e is the eccentricity, rp is the periastron, a is the semimajor axis, T is the orbital period, Δt is the time since the most recent periastron, and tclose is the amount of time the two stars spend close together (see ‘Orbital solutions’ in the Methods).
