General Description

MIDI observations of three Young Stellar Objects. 
We want to obtain three visibility points per target. With these observations we
want to measure the 10 micron silicate bump arising from the surface of the 
rotating disks around the three sources. Comparing these observations with 
the UVES spectra (run A) will allow us to study the thermal coupling state 
of the gas and the dust in the proto-planetary disks.
Since some targets might be too faint for fringe detection in the requested mode,
 a more sensitive mode is authorized if no fringe can be dedected.

Critical Observing Condition Constraints

No special observing condition requested

Time-Critical Aspects

Due to the time variability of the sources emission the MIDI observations
need to be carried out quasi-simultaneously to the UVES observations (run A).
These MIDI OBs need to be carried out within 3 or 4 weeks from the UVES OBs whose
 
name is labelled with "B1". Namely:
This run should be excecuted within 3 or 4 weeks from the following UVES OBs (run
 A):
HD101412_UVES_B1_0, HD101412_UVES_B1_90,
HD135344_UVES_B1_0, HD135344_UVES_B1_90,
HD179218_UVES_B1_0, HD179210_UVES_B1_90.
