Session 3: Future observing strategy and modeling developments
Wednesday pm, Thursday am
- Forgetting about observational limitations:
1) what do we want to know ?
2) what do we need to measure ?
- Modeling approaches / theoretical developments (*Lopez Ariste)
- convection / MHD (?) / line profile comparison
- molecules and dust formation, chemistry
- local and global magnetic fields
- Impact of Gaia parallaxes (TGAS Sept. 2016 + later) (*Kervella)
- Choice of targets (*Ridgway):
- Red supergiants (Betelgeuse, Antares, VY CMa, mu Cep,...)
- AGB/post-AGB targets (L2 Pup, R Dor, Mira, CW Leo,...)
- Strategy for spectroscopy / spectropolarimetry (*Lèbre)
UVES, HARPS, CRIRES, VISIR,...
- Strategy for AO / HST / JWST / E-ELT observations (*Perrin)
SPHERE, NACO, STIS, FGS,...
- Strategy for VLTI/CHARA/NPOI(?) proposals (*Paladini)
GRAVITY, VEGA, PIONIER, future MATISSE
- Strategy for ALMA Cycle 5 / NOEMA / eMerlin: large program(s) ? (*Richards)
Summary and conclusions (*Ridgway)
Thursday pm (end at 16:00)
- Scheduling of subsequent actions, road map (ESO and ALMA proposals, others,...)
