Seismic age estimates for the four g-mode stars in NGC 2516. The stars are vertically ordered by increasing Gaia colour index G_BP − G_RP. Horizontal error bars indicate the individual seismic ages derived using Approach 1. The vertical grey line and the grey shaded region mark the seismic age and ±1σ range obtained from joint modelling of all the four stars using Approach 2 (“Seismic joint fitting”). The vertical blue shaded region represents the MIST isochrone age derived from CMD fitting. The vertical gold shaded region represents the age derived using our own isochrone deduced from the seismic model grid, see Section 5.
