Analytical Lunar Ephemeris: Brouwer's Suggestion

Abstract

in the main problem of lunar theory, elimination of the monthly terms brings in divisors in the form (j+km), where m is the ratio n'/n. Delaunay develops them systematically in powers of m. Brouwer sug- gested examining whether these binomial expansions could be the primary cause of slow convergence in the powers of m. The answer to that question is in the negative.
