Abstract:
The luminosities and effective temperatures, as well as the whole
bolometric light curves of non-linear convective RR Lyrae models with
0.0001≤Z≤0.006, are transformed into the Sloan Digital Sky Survey
(SDSS) photometric system. The obtained ugriz light curves, mean
magnitudes and colours, pulsation amplitudes and colour-colour loops
are shown and analytical relations connecting pulsational to intrinsic
stellar parameters, similar to the ones currently used in the
JohnsonCousins filters, are derived. Finally, the behaviour in the
colour-colour planes is compared with available observations in the
literature and possible systematic uncertainties affecting this
comparison are discussed.
