We present high-resolution CARMA 230 GHz continuum imaging of nine deeply embedded protostars in the Serpens Molecular Cloud , including six of the nine known Class 0 protostars in Serpens .
This work is part of a program to characterize disk and envelope properties for a complete sample of Class 0 protostars in nearby low-mass star forming regions .
Here we present CARMA maps and visibility amplitudes as a function of uv -distance for the Serpens sample .
Observations are made in the B , C , D , and E antenna configurations , with B configuration observations utilizing the CARMA Paired Antenna Calibration System .
Combining data from multiple configurations provides excellent uv -coverage ( 4 - 500 k \lambda ) , allowing us to trace spatial scales from 10 ^ { 2 } to 10 ^ { 4 } AU .
We find evidence for compact disk components in all of the observed Class 0 protostars , suggesting that disks form at very early times ( t < 0.2 Myr ) in Serpens .
We make a first estimate of disk masses using the flux at 50 k \lambda , where the contribution from the envelope should be negligible , assuming an unresolved disk .
The resulting disk masses range from 0.04 ~ { } \mbox { M$ { } _ { \odot } $ } to 1.7 ~ { } \mbox { M$ { } _ { \odot } $ } , with a mean of approximately 0.2 M _ { \odot } .
Our high resolution maps are also sensitive to binary or multiple sources with separations \gtrsim 250 AU , but significant evidence of multiplicity on scales < 2000 AU is seen in only one source .
