Abstract:
This is the second in a series of papers based on data from DISCS, a
Submillimeter Array observing program aimed at spatially and
spectrally resolving the chemical composition of 12 protoplanetary
disks. We present data on six Southern sky sources -IM Lup, SAO 206462
(HD 135344b), HD 142527, AS 209, AS 205, and V4046 Sgr- which
complement the six sources in the Taurus star-forming region reported
previously. CO 2-1 and HCO+ 3-2 emission are detected and resolved
in all disks and show velocity patterns consistent with Keplerian
rotation. Where detected, the emission from DCO+ 3-2, N2H+ 3-2,
H2CO 3_0 3-20 2_ and 4_1 4-31 3_, HCN 3-2, and CN 2_3 3/4/2-12
2/3/1_ are also generally spatially resolved. The detection rates are
highest toward the M and K stars, while the F star SAO 206462 has only
weak CN and HCN emission, and H2CO alone is detected toward HD 142527.
Description:
Two frequency setups per source were selected to cover four to eight
spectral lines in each setup (centered at 1.1mm and 1.4mm), at the
same time providing continuum observations. The targeted molecules are
DCO+ and DCN (probing deuterium chemistry and cold gas), CN and HCN
(probing photochemistry), HCO+ (probing ionization), N2H+
(potential CO freeze-out tracer), H2CO and CH3OH (potential grain
chemistry products), c-C3H2 (carbon-chain chemistry), and CO (the
disk kinematic tracer).
