    • n ephemeris In astronomy, a table or a collection of tables or data showing the daily positions of the planets or heavenly bodies, or of any number of them; specifically, an astronomical almanac, exhibiting the places of the heavenly bodies throughout the year, and giving other information regarding them, for the use of the astronomer and navigator. The chief publications of this sort are the French “Connaissance des Temps” (from 1679), the British “Nautical Almanack and Astronomical Ephemeris” (from 1766), the Berlin “Astronomisches Jahrbuch” (from 1776), and the “American Ephemeris and Nautical Almanac” (from 1855).
    • n ephemeris Anything lasting only for a day or for a very brief period; something that is ephemeral or transient; especially, a publication or periodical of only temporary interest or very short duration.

In science:

They can be applied to a number of principal problems of modern astronomy and timekeeping metrology including the search for stochastic gravitational wave background in the early universe, testing General Relativity and establishing of new ephemeris time scale.
Millisecond and Binary Pulsars as Nature's Frequency Standards. II. Effects of Low-Frequency Timing Noise on Residuals and Measured Parameters
We used the DE200 ephemeris of the Jet Propulsion Laboratory (Standish 1982) to transform the TOAs to the solar system barycenter and the Blandford & Teukolsky (1976) model for timing pulsars in binary systems.
Millisecond Pulsar Velocities
Millisecond and binary pulsars are the most stable natural frequency standards which admits to introduce modified versions of universal and ephemeris time scales based correspondingly on the intrinsic rotation of pulsar and on its orbital motion around barycenter of a binary system.
