Do tides destabilize Trojan exoplanets?
2022, IcarusCitation Excerpt :Thus it is plausible that energy dissipation may increase the amplitude of tadpole librations, and ultimately may destabilize Trojan orbits. Many papers have addressed the effects of various types of dissipation on Trojans in our Solar System, such as drag by nebular gas and dust (Jeffreys, 1929; Greenberg, 1978; Yoder, 1979; Peale, 1993; Murray, 1994; Leleu et al., 2019), radiation pressure and its associated Poynting–Robinson drag (Colombo et al., 1966; Schuerman, 1980; Simmons et al., 1985), and even torques from planetary rings (Lissauer et al., 1985). These studies show that energy dissipation can either damp or pump orbital eccentricity and libration, depending on the particular functional form of the drag (Yoder et al., 1983; Murray, 1994).
The Origin of the Natural Satellites

2011, IcarusCitation Excerpt :There has been much debate over the origin of this asymmetry and at one point the mystery even found its way into a popular work of science fiction (Clarke, 1993). Drag forces acting on Trojan particles are known to act asymmetrically (Peale, 1993; Marzari and Scholl, 1998; Kortenkamp and Hamilton, 2001), but in the wrong sense, favoring trapping into the trailing L5 rather than the leading L4. Planetary migration is known to induce an asymmetrical trapping of objects into other resonances (Murray-Clay and Chiang, 2005), so perhaps migration similarly influences Trojan trapping.

2009, IcarusCitation Excerpt :This property results from the constant slopes measured by Jewitt (2002a) and our above extrapolation. The jovian Trojans, asteroids confined to two swarms at the L4 and L5 Lagrangian points of the Sun–Jupiter system, were long thought to have accreted very early from near-Jupiter planetesimals, possibly during the final growth period of the planet (e.g., Shoemaker et al., 1989; Peale, 1993; Kary and Lissauer, 1995; Marzari and Scholl, 1998; Fleming and Hamilton, 2000). Trojans could therefore represent a small fraction of the population of planetesimals which formed among the giant planets, the bulk of them having been ejected from the Solar System.
