SUMMARY:Molecules in star- and planet-forming regions: from ice cold to st
 eaming hot - Ewine van Dishoeck\,  Leiden

DESCRIPTION:The earliest stages of star- and planet formation are obscured
  by tens\nto hundreds of magnitudes of extinction. Observations of the gas
  and\ndust at long wavelengths often provide the only way to obtain\ninfor
 mation on the physical and chemical processes that occur deep\ninside thes
 e regions.  In this talk\, an overview of Spitzer\, VLT\, and\nJCMT spectr
 oscopic observations of ices\, silicates\, PAHs and hot gases\nwill be giv
 en. Spitzer has opened up the possibility to obtain high\nquality mid-infr
 ared spectra for large numbers of low-mass protostars\nand disks around so
 lar-mass pre-main sequence stars for the first\ntime\, whereas VLT-CRIRES 
 provide complementary high spatial and\nspectral resolution data down to 1
  AU.  The results will be analyzed\nusing models of evolving protostellar 
 envelopes and disks\, including\ntransitional disks with inner holes and g
 aps in which planets may have\nformed. The diagnostic values of the variou
 s lines and bands will be\nemphasized\, and the importance of laboratory d
 ata to interpret them\nwill be illustrated.  Initial Herschel Space Observ
 atory results will\nbe presented.  The prospects for future facilities\, i
 n particular\nHerschel\, the James Webb Space Telescope and the Atacama La
 rge\nMillimeter Array\, will be discussed.\n\n
