Scientific paper
The authors report photometric observations of mutual Pluto-Charon eclipses in April 1986 and non-detection of eclipses in April 1985. Combining their data with previously published shallow eclipse events in early 1985 they determine radii of (1100±70) km and (580±50) km for Pluto and Charon, respectively, and deduce a systemic mean density ρ = (2.1±0.5) g/cm3 and geometric albedos p = 0.63±0.10 for Pluto and p = 0.49±0.10 for Charon. The rotational period of Pluto agrees to within 0.003% with the binary orbital cycle, with an upper limit of the projected eccentricity (e cos ω) of 0.002. Both findings confirm that the Pluto-Charon system is completely tidally evolved.
