This paper continues the study of the properties of an accretion discrotating around a non-baryonic (assumed super-massive) compact object. Thiskind of objects, generically known as boson stars, were earlier proposed as apossible alternative scenario to the existence of super-masive black holes inthe center of every galaxy. A dilute boson star has also been proposed as alarge part of the non-baryonic dark matter, flattening galactic rotationalvelocities curves. In this contribution, we compute the profile of the emissionlines of Iron; its shape has been for long known as a useful diagnosis of thespace-time geometry. We compare with the case of a Schwarzschild black hole,concluding that the differences are observationally distinguishable.Comment: 14 pages, 7 figure
