Abstract

We present an evolutionary model for gamma-ray line emission from superbubbles based on shock acceleration of metal-rich stellar ejecta. Application to the Orion OB1 association shows that gamma-ray lines at the detection threshold of the SPI spectrometer aboard of INTEGRAL are expected, making this region an interesting target for studies of the interaction of supernova shocks with the interstellar medium.
