The presence of a stellar companion can place constraints on occurrence and orbital evolution of satellites orbiting exoplanets, i.e., exomoons. In this work we revise earlier orbital stability limits for retrograde orbits in the case of a three-body system consisting of a star, planet, and satellite. The revised limit reads asatcrit≈0.668(1−1.236ep) for e p ≤ 0.8 in units of the Hill Radius and represents the lower critical orbit as a function of the planetary eccentricity e p. A similar… 
Updated studies on exomoons in the HD 23079 system
Abstract We re-evaluate the outer edge of orbital stability for possible exomoons orbiting the radial velocity planet discovered in the HD 23079 system. In this system, a solar-type star hosts a

Celestial Mechanics and Dynamical Astronomy
1. Dynamics of Extrasolar Planets (C. Beaugé) The orbital fits of multi-planetary systems from radial velocity data has proved to be a complex task. In some cases, different orbital solutions provide
New developments for modern celestial mechanics – I. General coplanar three-body systems. Application to exoplanets
Modern applications of celestial mechanics include the study of closely packed systems of exoplanets, circumbinary planetary systems, binary-binary interactions in star clusters, and the dynamics of
Imaging low-mass planets within the habitable zone of α Centauri
Sensitivity to warm sub-Neptune-sized planets throughout much of the habitable zone of α Centauri A is demonstrated, an order of magnitude more sensitive than state-of-the-art exoplanet imaging mass detection limits.
The exomoon corridor: Half of all exomoons exhibit TTV frequencies within a narrow window due to aliasing
Exomoons are expected to produce potentially detectable transit timing variations (TTVs) upon their parent planet. Unfortunately, distinguishing moon-induced TTVs from other sources, in particular
Application of Orbital Stability and Tidal Migration Constraints for Exomoon Candidates
Satellites of extrasolar planets, or exomoons, are on the frontier of detectability using current technologies and theoretical constraints should be considered in their search. In this Letter, we
Habitable Zones in Binary Star Systems: A Zoology
Several concepts have been brought forward to determine where terrestrial planets are likely to remain habitable in multi-stellar environments. Isophote-based habitable zones, for instance, rely on
The ominous fate of exomoons around hot Jupiters in the high-eccentricity migration scenario
All the giant planets in the solar system host a large number of natural satellites. Moons in extrasolar systems are difficult to detect, but a Neptune-sized exomoon candidate has been recently found
Detecting Exoplanets Using Eclipsing Binaries as Natural Starshades
We investigate directly imaging exoplanets around eclipsing binaries, using the eclipse as a natural tool for dimming the binary and thus increasing the planet to star brightness contrast. At
