# Can someone calculate the age of the KOI-4878 star?

The star’s low metallicity and fairly high space velocity suggest that KOI-4878 is older than the Sun.

But I don't know how to calculate an estimation for the age.

• You probably want to look if it has been picked up by an asteroseismic survey. Given that its a KOI, this could be true. Ages from asteroseismology are the most accurate ones, particularly that this star is a G4. – AtmosphericPrisonEscape Oct 2 '19 at 23:22
• @AtmosphericPrisonEscape Where would one look for that? – B--rian Mar 12 at 12:29
• @B--rian: I would think the relevant archives should be those with accurately sampled photometric time series data, i.e. Corot, Kepler, Tess. But I see you already posted the link to the exoplanet archive, which does link all those info together, if available. If standard methods (isochrone fitting, seismology) would allow the age determination, I suspect it would already have been done. – AtmosphericPrisonEscape Mar 12 at 12:38
• @AtmosphericPrisonEscape Thanks for the hints, made me realize that I do not understand the exoplanet archive well enough - all I see is that there is no obvious entry age. – B--rian Mar 12 at 12:48

A search with the keyword KOI-4878.01 on different publication databases like arXiv or scholar.google did not help either.
