Welcome to the VLA Nascent Disk and Multiplicity (VANDAM) Survey Website!

The VANDAM survey is a 264 hour Karl G. Jansky Very Large Array (VLA) survey of all known protostars in the Perseus molecular cloud, at a distance of ~230 parsecs. The survey is being conducted at wavelengths of 8 mm, 1 cm, 4cm and 6.4 cm using the Ka-band and C-band receiver systems. The observations are being conducted in two array configurations at Ka-band; A configuration for the highest resolution and B configuration for more sensitivity to compact, extended structure. The best resolutions in A and B configurations are is ~0.065" (15 AU) and in B-configuration ~0.2 46 AU), respectively.
