Stellar Tracks

Class providing models of stellar tracks in luminosity and effective temperature as a function of initial mass, metallicity, and age.

Default implementation: stellarTracksFile

Methods

luminosity → double precision

Returns the bolometric luminosity of a star of given initialMass, metallicity and age.

  • double precision, intent(in ) :: initialMass, metallicity, age

temperatureEffective → double precision

Returns the effective temperature of a star of given initialMass, metallicity and age.

  • double precision, intent(in ) :: initialMass, metallicity, age

stellarTracksFile

A stellar tracks class in which luminosities and effective temperatures of stars are computed from a tabulated set of stellar tracks, read from file and interpolated. The file containing the tracks to use is specified via the stellarTracksFile parameter. The file specified must be an HDF5 file with the following structure:

stellarTracksFile
 |
 +-> metallicity1
 |    |
 |    +-> metallicity
 |    |
 |    +-> mass1
 |    |    |
 |    |    +-> mass
 |    |    |
 |    |    +-> age
 |    |    |
 |    |    +-> luminosity
 |    |    |
 |    |    +-> effectiveTemperature
 |    |
 |    x-> massN
 |
 x-> metallicityN

Each metallicityN group tabulates tracks for a given metallicity (the value of which is stored in the metallicity dataset within each group), and may contain an arbitrary number of massN groups. Each massN group should contain a track for a star of some mass (the value of which is given in the mass dataset). Within each track three datasets specify the age (in Gyr), luminosity (in \(L_\odot\)) and effectiveTemperature (in Kelvin) along the track.

(Default implementation)

Methods

  • readFile — Read the named power spectrum file.

Parameters

  • [forceZeroMetallicity] (default .false.) — Force the use of zero metallicity (or lowest metallicity available) for all stellar populations.

  • [fileName] — The path to the HDF5 file containing the tabulated stellar population spectra, with datasets for ages (Gyr), metallicities (log Solar), wavelengths (AA), and spectra (\(L_\odot\,\mathrm{Hz}^{-1}\)); see the scripts/ssps folder for conversion scripts.

  • [fileName] — The name of the file which contains fit coefficients for the time per tree fitting function.

  • [fileName] (default inputPath(pathTypeDataStatic)//'stellarAstrophysics/stellarPropertiesCompilationStandard.xml') — The name of the XML file from which to read stellar properties (ejected masses, yields, etc.).

  • [fileName] (default inputPath(pathTypeDataStatic)//'stellarAstrophysics/Stellar_Tracks_Padova.hdf5') — The name of the HDF5 file from which to read stellar tracks.

  • [fileName] — The name of the file from which to read intergalactic medium state data.

  • [fileName] — The name of the file from which to read intergalactic background light properties.

  • [fileName] — The name of a file from which to read tabulated spectra of accretion disks.

  • [fileName] — The name of the file from which to read a tabulated transfer function.
