Uppsala-DLR Trojan Survey
Uppsala-DLR Trojan Survey (UDTS) is the name of a project to study the positions and movements of asteroids near Jupiter . The focus is on asteroids in the Lagrange points of Jupiter and those that are shielded from direct observation by the planet. This group, of which more than 7000 objects have already been discovered, are known as Trojans and each of them bears the name of a Greek (L4) or Trojan (L5) hero. The study was carried out at the Uppsala Astronomical Observatory in cooperation with the German Aerospace Center (DLR) by astronomers Claes-Ingvar Lagerkvist , Gerhard Hahn , Stefano Mottola , Magnus Lundström and Uri Carsenty .
The Schmidt telescope of ESO was set up in autumn 1996, an area around the Lagrange point L4 study of Jupiter. The results were confirmed and supplemented by additional observations with the 0.6 m Bochum telescope of the La Silla observatory . The object P / 1997 T3 discovered during this investigation caused remarkable discussions, as it shows the appearance of an asteroid on the one hand, but has a comet-like tail on the other. The prevailing belief is that this tail is made of dust as it has a consistent appearance and faces the sun rather than away from it.
The Uppsala-DLR Trojan Survey can easily be confused with the Uppsala-DLR Asteroid Survey , but has different objectives.
