Abstract:
Core condensation is a critical step in the star-formation process,
but it is still poorly characterized observationally.
We have studied the 10pc-long L1495/B213 complex in Taurus to
investigate how dense cores have condensed out of the lower density
cloud material.
We observed L1495/B213 in C18O(1-0), N2H+(1-0), and
SO(JN=32-21) with the 14m FCRAO telescope, and complemented the
data with dust continuum observations using APEX (870um) and IRAM 30m
(1200um).
Description:
Fit results for all the C18O(1-0) and N2H+(1-0) FCRAO spectra
obtained in CLASS. Only those components with SNR≥3 are presented.
