data stars

Stars are emissive bodies, illuminating the other bodies of the parent system.

Parameters

• type: star
• name: list of names of the star, mandatory.
• body-class: Body category, optional, unless 'reflective' class has been used.
• radius: radius of the body, mandatory, in kilometers, if not set it is calculated from the effective temperature.
• diameter: diameter of the body, optional, in kilometers, ignored if radius is specified.
• axes: Three axes diameter of the body, optional, in kilometers, ignored if radius or diameter is specified.
• ellipticity : Oblateness of the body, optional, default value is 0, ignored if axes is specified.
• temperature: effective temperature in Kelvin of the surface of the star, optional, if not set it is calculated from the spectral type of the star.
• magnitude: absolute magnitude of the star, mandatory.
• spectral-type: spectral type of the star, mandatory.
• orbit: orbit of the star, mandatory, see the orbits page.
• rotation: rotation of the star, mandatory, see the rotations page.
• albedo : Geometric albedo of the body, optional, default value is 0.5.
• point-color : Color of the body when seen as point source, optional, default value is [1, 1, 1].
• surfaces : List of the surfaces of the body, optional, see the surfaces page.
• surface-factory : Name of the surface generator, optional, default is 'default'.
• clouds : Clouds of the body, optional, see the clouds page.
• rings : Rings of the body, optional, see the rings page.
