Day 0 (17/Aug/2015)
- We will provide instructions to install/run our codes to the successful applicants. If you need help to install the required tools, we will provide support on a best-effort basis for the installation of MOOG 2014, python codes (q2 and others), and IRAF.
- The support will be provided in the afternoon of Monday 17/Aug/2015, the day before we start Precision Spectroscopy. Support regarding installation of the required programs will be also provided during the workshop, on a best-effort basis.
- Planning observations: sample stars, reference star(s), spectrograph.
- Data reduction: continuum normalization.
- Construction of iron line lists (why keep “difficult” lines: low EP, Fe II).
-- Equivalent width (EW) measurements by hand: Gaussian vs. Voigt profiles, continuum, blends, line-by-line comparison, line-by-line measurements.
- Automatic codes to measure EW (why we shouldn’t blindly rely on them).
[Opportunity to compare the “manual” measurements with automatic ones]
Contributed talks on the connection between stars and planets.
Hands-on practice.
Day 2
- Curve of growth method (what does MOOG do?)
- Differential spectroscopic equilibrium: re-measurement of outliers, stellar parameters, manual and automatic spectroscopic equilibrium.
- Error estimates: statistical and systematic.
Contributed talks on stellar astrophysics (stellar evolution effects, stellar activity).
Hands-on practice.
Day 3
- “Absolute” effective temperatures and surface gravities.
- Photometric and H-alpha temperatures. Teff from line-depth ratios.
- Stellar ages and masses.
- Abundances of elements other than iron (HFS, isotopes)
- NLTE effects.
- Spectral synthesis.
Contributed talks on galactic chemical evolution.
Hands-on practice.
