exosim.tasks.sed.createPlanckStar

Classes

CreatePlanckStar

Create a star SED using the Planck function.

Module Contents

class CreatePlanckStar

Bases: exosim.tasks.task.Task

Create a star SED using the Planck function.

The star emission is simulated by astropy.modeling.physical_models.BlackBody. The resulting sed is then converted into \(W/m^2/sr/\mu m\) and scaled by the solid angle \(\pi \left( \frac{R}{D} \right)^2\).

Returns:

Star Sed

Return type:

Sed

Examples

>>> from exosim.tasks.sed import CreatePlanckStar
>>> import astropy.units as u
>>> import numpy as np
>>> createPlanckStar = CreatePlanckStar()
>>> wl = np.linspace(0.5, 7.8, 10000) * u.um
>>> T = 6086 * u.K
>>> R = 1.18 * u.R_sun
>>> D = 47 * u.au
>>> sed = createPlanckStar(wavelength=wl, T=T, R=R, D=D)

>>> import matplotlib.pyplot as plt
>>> plt.plot(sed.spectral, sed.data[0,0])
>>> plt.ylabel(sed.data_units)
>>> plt.xlabel(sed.spectral_units)
>>> plt.show()

execute()

Class execution. It runs on call and executes all the task actions returning the outputs. It requires the input with correct keywords
