Sample Projects for SOAR 4m telescope


1) Microquasars  (E. Janot-Pacheco)
Optical/IR spectroscopy and photometry of galactic superluminal sources. Search 
for correlation with radio variability. Studies of the central source.
FOV: ~ a few arcmin
FWHM: the best possible (as ~ 0.1")
S/N: >~100
Exp. time/moon phase: Min-hr; quite faint objects
Phot. dinamic range: large (?) 
Tip/tilt feasible
Queue: yes
Post-focus instrumentation requirs.: high/moderate spectral resolution 
(.~20,000)
Instruments IR (~1-3mu); Halpha
How soon? ? (variable sources; targets of opportunity?)
Why not Blanco? see PSF

2) Massive X-ray Binaries (E. Janot-Pacheco)
IR spectroscopic obsvs. of highly reddened (Galactic plane) candidates for 
source identification and X-ray emission modelling 
S/N: ~ 50
Time Exp.: minutes
Tip/tilt: yes
Number of  separate pointings to "complete": ~40/yr, 5 years?
Queue? yes
Post-focus instrum: low/moderate resolution spectroscopy (<~5000)
Instruments: IR spectrometer (HeI, Paschen)
Blanco? yes

3) Coronagraphy of circunstellar disks & weak stellar companions
(E. Janot-Pacheo)
Circumstellar envelope studies + discovery of planets/dwarf companions
FOV: < 5"?
PSF : FWHM <~ 0.1"
S/N: > 50
Exp. Time & moon phase: faint objects; It depends on the coronagraph
Phot. Dynamic range: "hihg"
Tip/tilt: yes?
Separate pointings: undefined
Queue: yes
Post-focus instrument: coronagraph
Blanco?: see PSF

All other items undefined and/or not astringents.
