Long-Term Evolution of Neptune Trojans

Neptune Trojans are objects that share the orbit with the planet Neptune and are in a neighborhood of the Lagrangian points L4 and L5 located 60({°) } "front" and 60({°) } "behind" the planet in its orbit. So far, there have been nine Neptune Trojans discovered. However stability studies indicate that this population should be large. In this work we report the results of numerical simulations of the evolution of fictitious Neptune Trojans, to detect stability and instability areas and also to study the escape of Trojans over the age of the Solar System.
