J/A+A/311/710       Faint Jovian satellites ephemerides (Rocher+, 1996)

Observations and ephemerides of the faint satellites of Jupiter Rocher P., Chapront J. <Astron. Astrophys. 311, 710 (1996)> =1996A&A...311..710R (SIMBAD/NED BibCode)
ADC_Keywords: Planets ; Ephemerides Keywords: ephemerides - planets and satellites: Jupiter Description: The observations of the faint satellites of Jupiter J6, J7, J8 and J9 have been collected. Numerical integrations have been performed and fitted to ancient and modern observations. Ephemerides of the equatorial jovicentric rectangular coordinates of the satellites are presented under the form of Poisson series, covering 150 years from 1900. Numerical tools (tables and softwares) are provided to the users for a practical reconstruction of the ephemerides. Author's Address: P. Rocher, J.

Explanations: The program satxjup.f computes the geocentric positions of Jupiter satellites J6, J7, J8, J9 for 10 values of the time (dynamical time) with 5400 days step. Starting Julian date = 2415020.5 (1900/Jan./10h). The resulting values appear on the screen : geocentric rectangular positions X, Y, Z (AU) of the satellites (equinox and equator J2000) Courtesy: P.
