The Uppsala-DLR Trojan Survey of the Preceding Lagrangian Cloud

“…In the two uppermost panels the suggested 1 Gyr stability zone from Levison et al (1997) is included. The family suggested by Shoemaker et al (1989) and by Milani (1993) is clearly seen in the lower, left part of the figure close to (40,7). .…”

“…One object deviating more than normal is (2146) Stentor which, however, is a special case since it is close to a secular resonance . Milani (1993) gives a value of 0.0226 for the eccentricity, suggests 0.06 and Shoemaker et al (1989) 0.067. Our value of the proper eccentricity was derived to 0.060.…”

“…Since the sample theorem is violated (Råde and Westergren 1995) the data is processed without frequency filtering. A data set of proper elements of Trojans were published by Milani (1993), giving parameters for 85 numbered and 89 at that time unnumbered Trojans. Comparing the values of the numbered objects we get for the libration amplitudes ( ), eccentricities ( Ô ) and inclinations ( Ô ) very small differences between the two sets of data.…”

“…Some of these has already been suggested like the one at ¼ AE and Ô AE in L as the 3548 Eurybates group (Shoemaker et al 1989). Trojan families were also studied by Milani (1993) and Beaugé and Roig (2001). However, an investigation of the Trojan families is in preparation.…”
