Аннотация:The problem of registration of collapsing stars in the Galaxy is considered using two instruments: the optoacoustic gravitational detector OGRAN and the neutrino telescope BUST, located in the underground laboratories of the Baksan Neutrino Obstrvatory of the Institute for Nuclear Research of the Russian Academy of Sciences (BNO INR RAS). An algorithm for joint data processing on the experience of registration of the SN1987A event is presented. The proposed method is illustrated by the current output signals ofthese instruments.
