On the tidal radius of satellites on prograde and retrograde orbits
Grzegorz Gajda, Ewa L. Lokas
A tidal radius is a distance from a satellite orbiting in a host potential beyond which its material is stripped by the tidal force. We derive a revised expression for the tidal ra…

The origin of prolate rotation in dwarf spheroidal galaxies formed by mergers of disky dwarfs
Ivana Ebrova, Ewa L. Lokas
Motivated by the discovery of prolate rotation of stars in Andromeda II, a dwarf spheroidal companion of M31, we study its origin via mergers of disky dwarf galaxies. We simulate m…

The resonant nature of tidal stirring of disky dwarf galaxies orbiting the Milky Way
Ewa L. Lokas, Marcin Semczuk, Grzegorz Gajda +1
Using N-body simulations we study the tidal evolution of initially disky dwarf galaxies orbiting a Milky Way-like host, a process known to lead to the formation of dwarf spheroidal…
