Abstract (from CDS):
Besides the age–metallicity degeneracy, we examine the possible effects of other factors (horizontal branch morphology, blue straggler stars, binary interactions and α-enhancement) and give a quantitative analysis of the influences of these factors on age determinations (except for α-enhancement). For the colour and spectrum-fitting methods, the age can be underestimated by about 0.0–3.0, 0.0–2.0 and 0.0–3.0 Gyr owing to the influence of horizontal branch, blue straggler and binary stars, respectively. For the Lick-index method, the lower limit of maximal change of age is 6.0, 5.0 and 3.0 Gyr owing to the influence of horizontal branch, blue straggler and binary stars, respectively.
