Orbits of stars near galactic center

Original site: Since 1992 we have observed the central parsec of the galactic center in near infrared wavelengths. Until 2002 we mainly used our Speckle-Camera SHARP I on the NTT located at La Silla, Chile, for K band observations; since 2002 our main instrument is the adaptive optics assisted NIR-camera NAOS/CONICA at the VLT on Cerro Paranal, Chile, performing H, K and L imaging.
