Abstract
The main goal of the Large Volume Detector (LVD), in the INFN Gran Sasso National Laboratory, Italy, is the study of neutrino bursts from gravitational stellar collapses in our Galaxy or in the Magellanic Clouds. Both the detector and the data analysis procedure have been optimized for this purpose. No neutrino burst candidates were selected over 6013 days of observation. As a result, the 90% c.l. upper limit to the rate of gravitational stellar collapses in our Galaxy is 0.14y−1.
