Abstract
We searched for CS(7–6) emission in a range of young stars, to test for the presence of dense gas. CS emission was detected only towards high-luminosity objects. We suggest that this is because the low-luminosity objects cannot heat a sufficient volume of gas to produce detectable CS emission.
