Bases: BaseParameters

Class representing planet parameters.

Parameters:

name (str) – The name of the planet. Any characters are allowed. If you find that PSG is changing the name internally please submit an issue.
radius (astropy.units.Quantity) – The radius of the planet.
gravity (GravityParameters) – The gravity parameters of the planet.
semimajor_axis (astropy.units.Quantity) – The semi-major axis of the planet’s orbit.
orbit_period (astropy.units.Quantity) – The period of the planet’s orbit.
rotation_period (astropy.units.Quantity) – The rotation period of the planet.
eccentricity (float) – The eccentricity of the planet’s orbit
obliquity (astropy.units.Quantity) – The obliquity (tilt) of the planet.
obliquity_direction (astropy.units.Quantity) – The direction of the planet’s obliquity. The true anomaly at which the planet’s north pole faces away from the star.
init_phase (astropy.units.Quantity) – The initial phase of the planet.
init_substellar_lon (astropy.units.Quantity) – The initial substellar longitude of the planet.

Notes

The proxcenb class method initializes parameters specific to Proxima Centauri b.
The std class method initializes parameters for a standard exoplanet.

classmethod proxcenb(init_phase: astropy.units.Quantity, init_substellar_lon: astropy.units.Quantity)#

init_substellar_lon (astropy.units.Quantity) – The initial subsolar longitude of the planet.

Returns:

The planet parameters for Proxima Centauri b.

Return type:

PlanetParameters

classmethod std(init_phase: astropy.units.Quantity, init_substellar_lon: astropy.units.Quantity)#

The default VSPEC planet.

Parameters:
