boinor.constants.general¶
Astronomical and physics constants.
This module complements constants defined in astropy.constants, with gravitational paremeters and radii.
Note that GM_jupiter and GM_neptune are both referred to the whole planetary system gravitational parameter.
Unless otherwise specified, gravitational and mass parameters were obtained from:
Luzum, Brian et al. “The IAU 2009 System of Astronomical Constants: The Report of the IAU Working Group on Numerical Standards for Fundamental Astronomy.” Celestial Mechanics and Dynamical Astronomy 110.4 (2011): 293–304. Crossref. Web. DOI: 10.1007/s10569-011-9352-4
radii were obtained from:
Archinal, B. A. et al. “Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2009.” Celestial Mechanics and Dynamical Astronomy 109.2 (2010): 101–135. Crossref. Web. DOI: 10.1007/s10569-010-9320-4
J2 for the Sun was obtained from:
