Abstract. Stability of S-type and P-type planetary orbits in binary systems of different mass and separation ratios is investigated. Criteria for stable, marginally stable and unstable planetary orbits are specified. These criteria are used to determine regions of stability of planetary orbits in different binary systems with Jupiter-type planets. The obtained results show that the regions of stability for S-type orbits depend on the distance ratio between the star and planet, and the stellar companions, in the range of 0.22 and 0.46, depending on the mass ratio. For P-type orbits, the regions of stability also depend on that distance ratio, in the range of 1.75 and 2.45, again depending on the the mass ratio. Applications of these results to three observed binary systems with giant planets, namely, τ Boo, HD 195019 and GJ 86, show that the orbits of the giant planets in those systems can be classified as stable, as expected.

This paper studies the stability of S-type and P-type planetary orbits in binary systems. Stability limits are expressed in units of R AG /R AB , where R AG denotes the distance between the primary star and the planet and R AB denotes the distance between the two stars. The presentation about S-type orbits is correct, but concerning the P-type orbits (where the planet is orbiting both stars), the R AG /R AB ratios given in the paper are consistently too small by a factor of two, although the computations themselves are correct. This affects Sect. 4.2 of the paper, where Table 5 and Fig. 6 need to be modified (for corrections, see below). Moreover, in the Abstract, the Conclusions, and Sect. 4.3, it should read: for P-type orbits, the regions of stability also depend on that distance ratio, in the range of 3.50 and 4.90, again depending on the mass ratio.
