Orbits of 20 visual double stars discovered by P. Couteau are computed for the first time. The observations for four of these stars, COU 384, COU 1067, COU 1681, and COU 2388, span arcs greater than or approximately equal to 180 degrees. Since the time of their discovery the stars, COU 384 and COU 2388 have already completed one revolution. COU 338, COU 567, COU 1003, COU 1607, and COU2086 have many observations within small arcs and one or two observation sat more distant positions with small separations. The orbits of the remaining stars, COU 80, COU 532, COU 543, COU 613, COU 696, COU 936, COU 1129, COU 1667, COU 1904, COU 2244 and COU 2542, are determined from observations covering small arcs 10°–60°.

P. Couteau发现的视觉双星轨道
P. Couteau首次发现了由20个视觉双星组成的轨道。这些恒星中的四颗(COU 384,COU 1067,COU 1681和COU 2388)的观测跨度大于或近似等于180度的弧。自发现以来,COU 384和COU 2388等恒星已经完成了一次旋转。COU 338,COU 567,COU 1003,COU 1607和COU2086在小弧内有许多观测值,而一个或两个观测值位于更远的位置且间隔很小。余下的恒星的轨道,COU 80,COU 532,COU 543,COU 613,COU 696,COU 936,COU 1129,COU 1667,COU 1904,COU 2244和COU 2542,是根据对10°– 60°。
