Poster title: A sensitive probe of gas in Lupus proto-planetary disks using CN

Poster abstract: We obtained APEX data to do a pilot study to search for gas emission in a sample of protoplanetary disks 
in the Lupus molecular clouds, using the CN(3-2) line emission at 340 GHz as novel confusion-free probe of the kinematics 
of disks. Our main aim is to characterize the gas content of disks in the Lupus molecular clouds. The sample comprised 
eight T Tauris with strong continuum emission at 1.3 mm and with spectral types between K2 and M2. CN is a good tracer of 
the upper layers of the disk, where most other molecules are photodissociated. We report four (50%) new CN detections.
