Abstract:
Chemistry plays an important role in the structure and evolution of
protoplanetary disks, with implications for the composition of comets
and planets. This is the first of a series of papers based on data
from DISCS (Disk Imaging Survey of Chemistry with SMA), a
Submillimeter Array survey of the chemical composition of
protoplanetary disks. The six Taurus sources in the program (DM Tau,
AA Tau, LkCa 15, GM Aur, CQ Tau, and MWC 480) range in stellar
spectral type from M1 to A4 and offer an opportunity to test the
effects of stellar luminosity on the disk chemistry. The disks were
observed in 10 different lines at ∼3" resolution and an rms of
∼100mJy/beam at ∼0.5km/s.
Description:
Two frequency setups per source were selected to cover four to eight
spectral lines in each setup, at the same time providing continuum
observations. The targeted molecules are DCO+ and DCN (probing
deuterium chemistry), CN and HCN (probing photochemistry), HCO+ and
N2H+ (ions), H2CO and CH3OH (potential grain chemistry
products), c-C3H2 (carbon-chain chemistry), and CO (the disk
kinematic tracer). The SMA correlator covers ∼4GHz bandwidth in each
of the two sidebands (1.4mm and 1.1mm). The six disks were observed
from 2009 November through December with the compact configuration of
the SMA interferometer at Mauna Kea, Hawaii. LkCa 15 was also observed
on 2010 March 22 with the subcompact configuration.
