Star#

class ansys.stk.core.stkobjects.Star#

Bases: ISTKObject, ILifetimeInformation

Class defining the Star object.

Overview#

access_constraints

Get the constraints imposed on the star.

chain_analysis_options

Get the star’s chain analysis options.

epoch

Epoch of the star position information as a Julian epoch (yyyy.yy). The Julian epoch is related to the Julian date by the expression JD = 2451545.0 + (yyyy.yy - 2000.0) x 365.25, where 2451545.0 (TT) represents the standard J2000 epoch.

graphics

Get the star’s 2D Graphics properties.

graphics_3d

Get the star’s 3D Graphics properties.

location_declination

The star’s declination: the angle from the inertial equator measured toward the inertial positive Z-axis. Uses Angle Dimension.

location_right_ascension

The star’s right ascension: the angle in the equatorial plane measured in a right-handed sense about the inertial Z-axis from the inertial X-axis. Uses Angle Dimension.

magnitude

Magnitude, the visual brightness of the star. Dimensionless.

parallax

Annual parallax: motion of a star due to changes in the Earth’s position relative to the solar system barycenter. Uses Angle Dimension.

proper_motion_declination

Motion of the star relative to the solar system barycenter expressed in arc seconds per year. Here, declination refers to motion from the inertial equator measured towards the inertial positive Z-axis. Uses AngleRate Dimension.

proper_motion_right_ascension

Motion of star relative to solar system barycenter expressed in arc seconds per year. Here, right ascension refers to motion in equatorial plane measured in a right-handed sense about the inertial Z-axis from inertial X-axis. Uses AngleRate Dimension.

radial_velocity

The star’s radial velocity relative to the solar system barycenter. Uses Rate dimension.

reference_frame

Return a reference frame.
