Detailed Description

An instance of the Starburst99SEDFamily class represents a family of Starburst99 SEDs for single stellar populations (Leitherer et al. 1999, ApJS, 123, 3), assuming the Kroupa initial mass function (Kroupa 2001, MNRAS, 322, 231), parameterized on metallicity and age, and scaled by the initial mass of the SSP. The library data was prepared and bundled into a FITS file by Patrik Jonsson for use by the Sunrise code (2013ascl.soft03030J).

The SEDs are tabulated over a wavelength range from 0.009 $\mu \mathrm{m}$ to 160 $\mu \mathrm{m}$ with the spectral resolution shown in the figure below.

The data were downloaded from https://bitbucket.org/lutorm/sunrise/downloads/Patrik-imfKroupa-Zmulti-ml.fits.gz and converted to SKIRT stored table format for inclusion as a resource file. The stored table is opened during setup, and it is subsequently interpolated to the desired parameters and wavelength grid when needed.

When imported from a text column file, the parameters for this SED family must appear in the following order in the specified default units (unless these units are overridden by column header info):

$$M_{\mathrm{i}\mathrm{n}\mathrm{i}\mathrm{t}}({\mathrm{M}}_{\odot })Z(\mathrm{d}\mathrm{i}\mathrm{m}\mathrm{e}\mathrm{n}\mathrm{s}\mathrm{i}\mathrm{o}\mathrm{n}\mathrm{l}\mathrm{e}\mathrm{s}\mathrm{s})t(\mathrm{y}\mathrm{r})$$

Constructor & Destructor Documentation

Starburst99SEDFamily() [1/2]

Starburst99SEDFamily::Starburst99SEDFamily ( )

inlineprotected

Default constructor for concrete Item subclass Starburst99SEDFamily : "a Starburst99 SED family for single stellar populations" .

Starburst99SEDFamily() [2/2]

Starburst99SEDFamily::Starburst99SEDFamily ( SimulationItem *  parent )

explicit

This constructor can be invoked programmatically by classes that use a hard-coded SED family (as opposed to selected through the ski file). Before the constructor returns, the newly created object is hooked up as a child to the specified parent in the simulation hierarchy (so it will automatically be deleted), and its setup() function has been called.

Member Function Documentation

cdf()

double Starburst99SEDFamily::cdf ( Array &  lambdav, Array &  pv, Array &  Pv, const Range &  wavelengthRange, const Array &  parameters  ) const

overridevirtual

This function constructs both the normalized probability density function (pdf) and the corresponding normalized cumulative distribution function (cdf) for the SED with the specified parameters over the specified wavelength range. The function returns the normalization factor. The number and type of parameters must match the information returned by the parameterInfo() function; if not the behavior is undefined.

Implements SEDFamily.

intrinsicWavelengthRange()

Range Starburst99SEDFamily::intrinsicWavelengthRange ( ) const

overridevirtual

This function returns the intrinsic wavelength range of the SED family. It retrieves this range from the underlying stored table.

Implements SEDFamily.

parameterInfo()

vector< SnapshotParameter > Starburst99SEDFamily::parameterInfo ( ) const

overridevirtual

This function returns the number and type of parameters used by this particular SED family as a list of SnapshotParameter objects. Each of these objects specifies unit information and a human-readable descripton for the parameter.

Implements SEDFamily.

setupSelfBefore()

void Starburst99SEDFamily::setupSelfBefore ( )

overrideprotectedvirtual

This function opens the appropriate resource file (in SKIRT stored table format).

Reimplemented from SimulationItem.

specificLuminosity()

double Starburst99SEDFamily::specificLuminosity ( double  wavelength, const Array &  parameters  ) const

overridevirtual

This function returns the specific luminosity $L_{\lambda }$ (i.e. radiative power per unit of wavelength) for the SED with the specified parameters at the specified wavelength, or zero if the wavelength is outside of the SED's intrinsic wavelength range. The number and type of parameters must match the information returned by the parameterInfo() function; if not the behavior is undefined.

Implements SEDFamily.
