Abstract:
We present the chemistry, temperature, and dynamical state of a sample
of 193 dense cores or core candidates in the Perseus Molecular cloud
and compare the properties of cores associated with young stars and
clusters with those which are not. The combination of our NH3 and CCS
observations with previous millimeter, submillimeter, and Spitzer data
available for this cloud enables us both to determine core properties
precisely and to accurately classify cores as starless or
protostellar.

Note (1): These reference numbers are from Rosolowsky et al. (2008,
Cat. J/ApJS/175/509; <[RPF2008] NH3SRC NNN> in Simbad), which
can be consulted for individual core positions and properties.
Note (2): Class as follows:
L = Starless,
S = Protostellar,
L? = Uncertain Starless,
S? = Uncertain Protostellar
Note (3): Evans et al. (2007, Final Delivery of Data from the c2d Legacy
Project: IRAC and MIPS (Pasadena, CA: Spitzer Science Center)),
considered associated if a YSO candidate falls within 1 FWHM of the
GBT beam (31") of the pointing location.
