[Planet]

This header is used to define planetary properties. Currently, only planet_type = simple is supported and must be included. planet_type = custom is also valid, See Custom Types

Class:

Planet

Keywords

Variable	Type	Description	Default
planet_mass	float	Mass in Jupiter mass	1.0
planet_radius	float	Radius in Jupiter radius	1.0
planet_distance	float	Semi-major-axis in AU	1.0
impact_param	float	Impact parameter	0.5
orbital_period	float	Orbital period in days	2.0
albedo	float	Planetary albedo	0.3
transit_time	float	Transit time in seconds	3000.0

Physical quantities are normalized to the documented units. For example, 48 * u.hour is stored as an orbital period of two days and 50 * u.min as a transit time of 3000 seconds. Impact parameter and albedo accept dimensionless quantities such as percentages.

Fitting Parameters

Parameter	Type	Description
planet_mass	float	Mass in Jupiter mass
planet_radius	float	Radius in Jupiter radius
planet_distance	float	Semi-major-axis in AU

Examples

Planet with 1.5 Jupiter mass and 1.2 Jupiter radii:
