Detailed Description

ModifiedLogNormalGrainSizeDistribution is a GrainSizeDistribution subclass that represents a modified log-normal dust grain size distribution of the form

$\frac{d n_{D}}{d a} \propto \frac{1}{a} \exp [- \frac{(\ln (a / a_{0}))^{2}}{2 σ^{2}}] M (a) for a_{min} \leq a \leq a_{max}$

with a mixing term

$M (a) = y_{0} + (y_{1} - y_{0}) \frac{\ln (a / a_{min})}{\ln (a_{max} / a_{min})} .$

The size range of the distribution can be configured in the RangeGrainSizeDistribution base class. The centroid $a_{0}$ and the width $σ$ can be configured in the LogNormalGrainSizeDistribution base class. The remaining two parameters $y_{0}$ and $y_{1}$ can be configured as attributes in this class. The function is scaled arbitrarily.

The functional form for the grain size distribution implemented by this class is inspired by the DustEM code, which is described in Compiègne et al. 2011 (AA, 525, A103) and can be downloaded from http://www.ias.u-psud.fr/DUSTEM/.

Constructor & Destructor Documentation

◆ ModifiedLogNormalGrainSizeDistribution()

ModifiedLogNormalGrainSizeDistribution::ModifiedLogNormalGrainSizeDistribution ( )

inlineprotected

Default constructor for concrete Item subclass ModifiedLogNormalGrainSizeDistribution : "a modified log-normal dust grain size distribution" .

Member Function Documentation

◆ dnda()

double ModifiedLogNormalGrainSizeDistribution::dnda ( double a ) const

overridevirtual

This function returns the value of $\frac{d n_{D}}{d a}$ as described in the header for this class (with an arbitrary proportionality factor of one).

Reimplemented from LogNormalGrainSizeDistribution.

◆ firstMixingParameter()

ModifiedLogNormalGrainSizeDistribution::firstMixingParameter ( ) const

inline

This function returns the value of the discoverable double property firstMixingParameter : "the first mixing parameter y0" .

The minimum value for this property is "[0" .

The maximum value for this property is "1]" .

The default value for this property is given by the conditional value expression "1" .

◆ secondMixingParameter()

ModifiedLogNormalGrainSizeDistribution::secondMixingParameter ( ) const

inline

This function returns the value of the discoverable double property secondMixingParameter : "the second mixing parameter y1" .

The minimum value for this property is "[0" .

The maximum value for this property is "1]" .

The default value for this property is given by the conditional value expression "1" .
