Abstract
In the last few years much multiwavelength observational evidence has accumulated suggesting that in some of the intermediate-mass llerbig Ae/Be stars, gas is accreting toward the central source at large terminal velocities. The most direct proof of this phenomenon has come from the analysis of the ultraviolet lines. Concurrent and complementary support for this interpretation are provided by diverse observations described here. We review the strong observational evidence from several of these objects in support of the concept of clumpy mass accretion occurring in their circumstellar environments.
