Resumen:
From the point of view of the intrinsic rotation, the Jupiter Trojansare not as well characterized as the main belt asteroids, primarilybecause the available sample of lightcurves is small and mainlyrestricted to the largest objects. We have obtained rotational periodsand lightcurve amplitudes for 6 Trojan asteroids, which range betweenvalues of 5.7hr and 9.6hr and 0.08mag and 0.59 mag respectively. Thissample includes an object of absolute visual magnitude H=11.5m, whichcorresponds to physical radii ranging from 35km to 22km, assumingalbedos between 4% and 10%. The values of the rotation periods found are consistent with those found for the Main Belt Asteroids in thesame size range.
