Stellar mass and age determinations. I. Grids of stellar models from Z=0.006 to 0.04 and M=0.5 to 3.5 M☉. Mowlavi N., Eggenberger P., Meynet G., Ekstrom S., Georgy C., Maeder A., Charbonnel C., Eyer L. <Astron. Astrophys. 541, A41 (2012)> =2012A&A...541A..41M
ADC_Keywords: Models, evolutionary Keywords: stars: evolution - stars: fundamental parameters - stars: low-mass - Hertzsprung-Russell diagram Abstract: We present dense grids of stellar models suitable for comparison with observable quantities measured with great precision, such as those derived from binary systems or planet-hosting stars. We computed new Geneva models without rotation at metallicities Z=0.006, 0.01, 0.014, 0.02, 0.03, and 0.04 (i.e. [Fe/H] from -0.33 to +0.54) and with mass in small steps from 0.5 to 3.5M☉. Great care was taken in the procedure for interpolating between tracks in order to compute isochrones. Description: File header: Indicates the number of tracks included in the file, and then lists the different tracks one after the other. For each track, a track header first summarizes general information on the track. Those are: - the type of track; - the metallicity, either Zinit or Zsurf depending on the type of track; - the age or the stellar mass of the track, depending on whether it is an isochrone or not; - the number of models in the track; - the model indexes of the reference points in the track. The reference points define phases in the following way: - phase 20: starts at the ZAMS, - phase 21: starts at the second (after ZAMS) reference point on the MS, - phase 22: starts at the third reference point, which corresponds to the occurrence of the first turn-off point on the MS or to the equivalent point if there is no hook, - phase 23: starts at the fourth reference point, which corresponds to the occurrence of the second turn-off point on the MS, or to the equivalent point if there is no hook, - phase 30: starts at the TAMS, - phase 31: base of the red giant branch.
