Ø Talk by Priyanka Chaturvedi
It is important for TLS to continue its participation in CARMENES
projectCARMENES is working well
CRIRES+ : A crossed dispersed high
resolution IR spectrograph
CRIRES+ is the only: The science:
• High resolution spectrograph • A search for super-Earths in the
working in Y, J, H, K, L, M habitable zone of low-mass
• R= 100,000 IR spectrograph on stars and brown dwarfs
an 8-m telescope • The characterization of
• Hires IR spectrograph in the atmospheres of transiting
southern hemisphere giant planets
• Has polarimetric capabilities • The origin and evolution of
stellar magnetic fields
Ø CRIRES+ will be the premier ground-based instrument
for the characterization of exoplanet atmospheres
Ø Consortium has 62 GTO nights
See CRIRES+ posterCRIRES+: Status Ø Shipped to Paranal end of 2019 Ø Slight delay in January due to rioting in Santiago Ø Warm commissioning completed in February Ø First light on 17.02.2020 Ø Cold commissioning in March and April (barring riots in Santiago) Ø Available to the community Fall 2020 (?) or 2021 First major instrument on VLT led by TLS
SOFIA
Ø TLS Scientists (Eislöffel, Stecklum, Sperling)
have received 36.2 hrs1 since 2015 (~6 % of
the flight time)
Ø Important for Star Formation work at TLS

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)You can also read
