File formats

听

In听, you will find the tracks corresponding to the latest grids. Their output spectrum are available听, and the isochrones generated with the new models are available听. So far, only the solar metallicity is available.

There are four types of files:

The names of the听evolution files听give information on the model considered:

  • the mass stands after the听M听(M085: 85 M鈯�; M2p5: 2.5 M鈯�);
  • the metallicity stands after the听Z听(Z14:听Z=0.014; Z02:听Z=0.002);
  • the rotation rate stands after the听V听(V0: no rotation; V4: V/Vcrit=0.40)

The names of the听isochrone files听give the following informations:

  • the metallicity stands after the听Z;
  • the rotation rate considered is indicated after the听V;
  • the log (age) stands after the听t.

The names of the听spectra files听give the following informations:

  • the related model, with the same naming convention as above;
  • the time-step number in 7 digits;
  • the听Tsurf听and log(L/L鈯�) of the model at that time step;
  • the type of data provided:
    • 听full spectrum =听spec;
    • 听normalised spectrum =听norm;
    • 听continuum only =听cont.

The names of the听X-UV evolution files听give the following informations:

  • the name of the host star of the planetary system;
  • the initial value of the surface rotation rate;
  • the type of rotator.
