We present a new comprehensive collection of stellar evolutionary tracks and isochrones for rotating low- and intermediate-mass stars assembled with the updated version of PARSEC V2.0. This version includes our recent calibration of the extra mixing from overshooting and rotation, as well as several improvements regarding the nuclear reaction network, treatment of convective zones, mass loss, and other physical input parameters. The initial mass of the stellar models covers the range 0.09 M-circle dot to 14 M-circle dot for six sets of initial metallicity, from Z=0.004 to Z=0.017. Rotation is considered for stars above similar to 1M(circle dot) with a smooth transition between non-rotating and extremely fast-rotating models, based on the initial mass. For stars more massive than similar to 1.3M(circle dot), the full rotation range, from low to critical, is considered. We adopt the solar-scaled chemical mixtures with Z(circle dot)=0.01524. All the evolutionary phases from the pre-main-sequence to the first few thermal pulses on the asymptotic giant branch or central C exhaustion are considered. The corresponding theoretical isochrones are further derived with TRILEGAL code and are converted into several photometric systems, taking different inclination angles into account. Besides magnitudes, they also offer many other stellar observables in line with the data being provided by current large surveys. The new collection is fully integrated in a user-friendly web-interface for the benefit of easily performing stellar population studies.

Abstract

We present a new comprehensive collection of stellar evolutionary tracks and isochrones for rotating low- and intermediate-mass stars assembled with the updated version of PARSEC V2.0. This version includes our recent calibration of the extra mixing from overshooting and rotation, as well as several improvements regarding the nuclear reaction network, treatment of convective zones, mass loss, and other physical input parameters. The initial mass of the stellar models covers the range 0.09 M-circle dot to 14 M-circle dot for six sets of initial metallicity, from Z=0.004 to Z=0.017. Rotation is considered for stars above similar to 1M(circle dot) with a smooth transition between non-rotating and extremely fast-rotating models, based on the initial mass. For stars more massive than similar to 1.3M(circle dot), the full rotation range, from low to critical, is considered. We adopt the solar-scaled chemical mixtures with Z(circle dot)=0.01524. All the evolutionary phases from the pre-main-sequence to the first few thermal pulses on the asymptotic giant branch or central C exhaustion are considered. The corresponding theoretical isochrones are further derived with TRILEGAL code and are converted into several photometric systems, taking different inclination angles into account. Besides magnitudes, they also offer many other stellar observables in line with the data being provided by current large surveys. The new collection is fully integrated in a user-friendly web-interface for the benefit of easily performing stellar population studies.
