In the interval JD2429100 - 38409 Min I = 2418357.0140; 3.5846794d(E - 406) - 0.429d cos alpha + 0.06d*sin(2alpha) + 0.010d*cos(3alpha) + 0.003d*sin(4alpha), MinII = 2418355.2220 + 3.5846794d(E - 406) + 0.429d cos alpha + 0.060D*sin(2alpha) - 0.010d cos*3alpha + 0.003d*sin(4alpha) (JD2416900 - 29100); Min I = 2429641.567 + 3.5846391d*(E - 3554) - 0.429d*cos(alpha) + 0.060d*sin(2alpha) + 0.010d*cos(3alpha) + 0.003d*sin(4alpha), Min II = 2429639.775 + 3.5846391d(E - 3554) + 0.429d*cos(alpha) + 0.060d*sin(2alpha) - 0.010d*cos(3alpha) + 0.003d*sin(4alpha), where alpha = 0.01245deg(E - 406) [D.Ya.Martynov, Astron. Zh. 42, 1209, 1965.]. The epochs E are being calculated for Min I from JD hel. 2416901.205, and for Min II - from JD hel. 2416900.248. In the interval JD2438409 - 41743 Min I = 2438409.6045 + 3.584586d(E - 6000) - 0.4290d*cos(alpha) + 0.0620d*sin(2alpha) + 0.0107d*cos(3alpha) + 0.0026d*sin(4alpha) - 0.00036d cos 5alpha, Min II = 2438407.8122 + 3.584586d(E - 6000) + 0.4290d cos alpha + 0.0620d*sin(2alpha) - 0.0107d*cos(3alpha) + 0.0026d*sin(4alpha) + 0.00036d*cos(5alpha), where alpha = 0.012385deg(E - 406) [D.Ya.Martynov, Astron. Zh. 51, Issue 1, 107, 1974.]. since JD2441743 - Min I = 2441743.2633 + 3.584670d(E - 6930) - 0.4336d cos alpha + 0.0634d*sin(2alpha) + 0.0111d*cos(3alpha) + 0.0021d*sin(4alpha), Min II = 2441741.4710 + 3.584689d(E - 6930) + 0.4336d cos alpha + 0.0634d*sin(2alpha) - 0.0111d*cos(3alpha) + 0.0021d*sin(4alpha), where alpha = 70.6deg + 0.0114deg(E - 6094) [D.Ya.Martynov, Astron. Tsirk. N1289, 1, 1983.]. Linear elements for Min I epochs in 1973 - 1990 are given in the Table. Corresponding elements for Min II epochs are: Min II = 2441741.575 + 3.584567d*E. E = 0.38. Apsidal motion period is 285 years. |
