  3. Thüringer Landessternwarte Tautenburg

  4. TLS: An International Institute Postdocs: Uzbekistan (Chretian Grant), Italy (EU RTN) Ph.D. Students: Brasil, Croatia, Italy, Spain, Ukraine,Venezuela, … Scientific Visitors: Canada, Egypt, Georgia, Italy, Ireland, USA, S. Korea, Ukraine, …

  5. Research Activities of TLS • Star formation, jets and outflows • Extrasolar planets and Brown Dwarfs • Magnetic activity on stars • Stellar oscillations • Gamma Ray Bursts • Quasars and active galaxies => Small institute, yet diverse

  6. Instrumentation of the Alfred-Jensch 2m Telescope Schmidt Camera: • 3.3o x 3.3o with photographic plates • ca. 10000 plates since 1960 • CCD Camera installed in 1996 • 50 x 50 arcmin FOV (0.7´´ per pixel) • Objective Prism (R~50)

  7. Instrumentation of the Alfred-Jensch 2m Telescope Naysmyth Faint Object Spectrograph: • Installed in 2001 • SITe 1024x800 CCD (0.53´´/pixel) • 5 grisms (100 to 230 A/mm) • 3500-10000 A

  8. Instrumentation of the Alfred-Jensch 2m Telescope Coude Echelle Spectrograph: • Installed in 1995 • R=67.000 • grism crossed dispersed: 3400-9270 Ang. • iodine absorption cell for precise radial velocity measurements Key Program: Radial Velocity Search for Extrasolar Planets Tautenburg Observatory Planet Search Program

  9. The Team: Radial Velocity Searches Thüringer Landessternwarte Tautenburg Artie Hatzes Eike Guenther (young stars, brown dwarfs) Massimiliano Esposito (young stars) Michael Hartmann (metal rich stars, A-type stars) ESO Michaela Döllinger (K giant planets and oscillations) Collaborators: Bill Cochran, Mike Endl, Barbara McArthur, Fritz Benedict (McDonald Observatory) – (M dwarf program with Endl) Martin Kürster (MPIA) David Mkrtichian (ARCSEC) Johny Setiawan (MPIA Heidelberg)

  10. Iodine cell

  11. HD 13189: The First Tautenburg Planet

  12. The Star M = 3.5 Msun [Fe/H] = –0.58 K2 II-III Schuler et al. (2005) The Planet

  13. b Gem CFHT McDonald 2.1m McDonald 2.7m TLS

  14. M* = 1.4 Solar Masses Sp.T. = F4 m sin i = 13 MJupiter Period = 328 d a = 1.06 AU e = 0.15

  15. Döllinger Ph.D. work: M* = 1.2 Solar Mass K giant m sin i = 6.6 MJupiter a = 0.86 AU Period = 266 d e = 0.45

  16. TOPS Program: Transit Confirmation Orbiting star M5 V Radius [Rsun] 0.35 Mass [Msun] 0.22

  17. The Team: Transit Searches Thüringer Landessternwarte Tautenburg Jochen Eislöffel Holger Voss Philipp Eigmüller RV Team for follow-up DLR (BEST collaboration) Heike Rauer Anders Erikson CoRoT German Team: Martin Pätzold Ludmilla Carone Günther Wuchterl + DLR Team

  18. The Tautenburg Exoplanet Search Telescope

  19. TEST first light Nov 2005… …but problems with mount and guiding

  20. BEST: 240 sec exposure 13.7 TEST: 30 sec exposure 1% photometry down to ~15 mag 13.4

  21. TLS Contributions to NAHUAL Person Power: • Small workshop that is overstretched → small parts • CAD work possible • Limited Electronics/Computer support • Expertise in absorption cell • Science contributions

  22. TLS Contributions to NAHUAL Money: • 80.000 – 100.000 in 2007 Budget • 2008/2009 Budget will be prepared early next year • Money has to be spent in a given budget year. Transfer to next year possible but difficult • Best to spread costs over several budget years • Specific items need to be identified and bids made • Memorandum of Understanding important
