Detailed Description

BlackBodySED is a class that describes black-body spectral energy distributions, i.e. the emission spectra of perfect absorbers which are in thermal equilibrium. Such an SED is characterized by the temperature of the object, and its spectrum is the Planck spectrum.

Whenever a tabular form of the black body SED is requested, this class uses a spectral resolution of \(R\triangleq\lambda/\Delta\lambda\geq 1000\) (see PlanckFunction::cdf()).

Constructor & Destructor Documentation

BlackBodySED()

BlackBodySED::BlackBodySED ( )

inlineprotected

Default constructor for concrete Item subclass BlackBodySED: "a black-body spectral energy distribution".

~BlackBodySED()

BlackBodySED::~BlackBodySED ( )

protected

This function destructs the Planck function object.

Member Function Documentation

generateWavelength()

double BlackBodySED::generateWavelength ( ) const

overridevirtual

This function draws a random wavelength from the normalized spectral energy distribution.

Implements SED.

integratedLuminosity()

double BlackBodySED::integratedLuminosity ( const Range & wavelengthRange ) const

overridevirtual

This function returns the normalized integrated luminosity \(L\) (i.e. radiative power) over the specified wavelength range.

Implements SED.

intrinsicWavelengthRange()

Range BlackBodySED::intrinsicWavelengthRange ( ) const

overridevirtual

This function returns the intrinsic wavelength range of the SED. For the BlackBodySED, the intrinsic range is unlimited, so this function returns a range including all representable positive floating point values.

Implements SED.

setupSelfBefore()

void BlackBodySED::setupSelfBefore ( )

overrideprotectedvirtual

This function constructs a Planck function object corresponding to the user-configured temperature and sets up the cumulative distribution that will be used to sample random wavelengths.

Reimplemented from SimulationItem.

specificLuminosity()

double BlackBodySED::specificLuminosity ( double wavelength ) const

overridevirtual

This function returns the normalized specific luminosity \(L_\lambda\) (i.e. radiative power per unit of wavelength) at the specified wavelength.

Implements ContSED.

specificLuminosityArray()

void BlackBodySED::specificLuminosityArray ( Array & lambdav, Array & pv, const Range & wavelengthRange ) const

overridevirtual

This function returns the normalized specific luminosity \(L_\lambda\) (i.e. radiative power per unit of wavelength) at a number of wavelength points within the specified wavelength range.

Implements ContSED.

temperature()

double BlackBodySED::temperature ( ) const

inline

This function returns the value of the discoverable double property temperature: "the black body temperature".

This property represents a physical quantity of type "temperature".

The minimum value for this property is "]0 K".

The default value for this property is given by the conditional value expression "5000 K".
