Irregular moons possibly injected from the outer solar system by a stellar flyby
Susanne Pfalzner, Amith Govind, Frank Wagner
The irregular moons orbit the giant planets on distant, inclined, and eccentric trajectories, in sharp contrast with the coplanar and quasicircular orbits of the regular moons. The…
Trajectory of the stellar flyby that shaped the outer solar system
Susanne Pfalzner, Amith Govind, Simon Portegies Zwart
Unlike the Solar System planets, thousands of smaller bodies beyond Neptune orbit the Sun on eccentric ( 0.1) and ( 3) orbits. While migration of the giant planets…
Unbound stars hold the key to young star cluster history
Arunima Arunima, Susanne Pfalzner, Amith Govind
Aims. GAIA delivers the positions and velocities of stars at unprecedented precision. Therefore, for star clusters, there exists much higher confidence in whether a specific star i…
Close stellar flybys common in low-mass clusters
Susanne Pfalzner, Amith Govind
Numerous protoplanetary discs show distinct spiral arms features. While possibly caused by a range of processes, detailed pattern analysis points at close stellar flybys as cause f…
