The formation of stars and planets from molecular cloud cores is a key area for research this decade. Crucial steps in this process can only be studied at mid-infrared to far-infrared wavelengths, where SIRTF provides an unprecedented improvement in sensitivity. We propose to use SIRTF (IRAC, MIPS, and IRS) to obtain data that span the evolutionary sequence from cores to planets, including a sampling of other variables, such as mass and environment, sufficient to separate these variables from evolution. In addition to observing known sources, we will scan large areas in molecular clouds for low luminosity sources and make a complete sample of nearby solar-type stars for debris disks. Spectroscopy of known objects spanning the full evolutionary range will be complemented by follow-up spectroscopy on new objects found in the surveys. The resulting data products will include catalogs of thousands of previously unknown sources, multiwavelength maps of very large regions, spectra of hundreds of sources, ancillary data, and new tools for analysis and modeling. These will provide many opportunities for follow-up studies with SIRTF, other space missions, including SIM, NGST, and TPF, and ground-based telescopes.
