Summary


Ø Performance indicators (publications, grant money)
  positive for past 20 years
Ø CARMENES, CRIRES+ projects finishing up
Ø PLATOSpec, CARMENES+, SkyHopper on the horizon
Ø TLS positioned to play an important role in PLATO follow
  up
Ø TLS ready to take next big step in its development, but
  we need support!
School Philosophy

• No pre-determined projects. We only
  make suggestions
• Students decide on objects to observe
• Students plan all the observations
• Students carry out all the observations
  including telescope and instrument
  control
Tautenburg International Observing
                  Schools


Benefits to TLS:
Ø Good advertising for TLS
Ø Excellent “niche” use of 2m telescope
Ø Attracts students to TLS-FSU
Ø Added value in funding proposals (DFG, EU)
