HabitableZoneAtmosphere()

template<typename T >

T EGXPhys::HabitableZoneAtmosphere	(	const T	planetMassInkg,
		const T	planetMeanRadiusInm,
		const T	planetEquilibriumTemperatureInK
	)

Calculates the Habitable Zone Atmosphere metric, \(HZA\), of a planet. The Habitable Zone Atmosphere is a measure of the potential of an exoplanet to hold a habitable atmosphere.

\[ HZA= \dfrac{ 2\sqrt{ \dfrac{m_p}{m_{\oplus}} / \dfrac{r_p}{r_{\oplus}} } -v_{eH} - v_{eN} }{v_{eH} - v_{eN}} \]

\[ v_{eH}=\sqrt{ \dfrac{z T_{eq}}{ M_wN } } \]

\[ T_{eq}=\sqrt{ \dfrac{z T_{eq}}{ M_wH } } \]

Parameters

planetMassInkg	\(m_{p}\ (kg)\) Mass of the planet in kilograms.
planetMeanRadiusInm	\(r_{p}\ (m)\) Mean radius of the planet in meters.
planetEquilibriumTemperatureInK	\(T_{eq}\ (K)\) Planetary equilibrium tempreture of a planet in kelvin.

Returns

\(HZA\ (dimensionless)\) Habitable Zone Atmosphere of a planet. Results between -1 and 1 means that the planet has the potential for a habitable atmospheric composition.
