luminosity_from_temperature(temperature: astropy.units.Quantity[pytmosph3r.util.pt.temperature], radius: astropy.units.Quantity[pytmosph3r.util.pt.length]) → astropy.units.W[source]

This function allows retrieving of the luminosity [Power] of a star behaving as a blackbody from its temperature [Temperature] and its radius [Length].

Parameters:

  • temperature (u.Quantity) – Effective temperature of the star.

  • radius (u.Quantity) – Radius of the star.

Returns:

Luminosity of the star in Watt [Power].

temperature_from_luminosity(luminosity: astropy.units.Quantity, radius: astropy.units.Quantity) → astropy.units.K[source]

This function allows retrieving of the effective temperature [Temperature] of a star behaving as a blackbody from its luminosity [Luminosity] and its radius [Length].

Parameters:

  • luminosity (u.Quantity) – Luminosity of the star.

  • radius (u.Quantity) – Radius of the star.

Returns:

Effective temperature of the star in Kelvin [Temperature].
