General Description

• The goal of this proposal is to obtain high spectral resolution (R~9000)
   K-band spectra of six nearly edge-on protoplanetary disks. The disks have been selected
   to be only moderately opaque in the near-infrared, so that a point source (the central
   source) actually peers out of the disk. With this geometry, we hope to detect the
   overtone rovibrational absorption lines of 12CO from the gas located along our line
   of sight in the protoplanetary disks. Both cold and warm components are expected,
   which we can study in a single ISAAC setting, covering the entire 2.29-2.41 micron
   range. We will determine the temperature and column densities of both components
   by constructing rotation diagrams based on the measured strength of the individual
   CO transitions.
  
  Ultimately, the goal of this proposal is to compare the CO column densities with
   that measures for molecular hydrogen through the absorbed X ray spectrum of the
   central young stellar object (as measured by XMM) and with that of dust, as determied
   by modelling of the short wavelength scattered light images of these edge-on disks.
  
  Each object should present extended nebulosity (possibly over many arcseconds) around
   a central point source. Please align slit on central point source to get the spectrum
   of the star, which will serve as a background source to detect the intervening gas
   located in the disk.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• The required observing conditions listed in each individual OBs are sufficient
   for our proposal.

Time-Critical Aspects

• This proposal does not have time-critical aspects.

Special Execution Requirements

• We do not have special execution requirements.

Special Calibration Information

• We do not require special calibration, as the Calibration Plan includes
   all the calibration we require for this proposal:
  
  - telluric standard (note that early-type, e.g. B4 or earlier) are strongly preferred
   to solar-like standard
  - day-time spectroscopic flats
  - day-time arc lamps
