Abstract
We use H α scanning Fabry-Perot interferometric data on the Orion Nebula in order to study the proplyds of the central region. We find that Fabry-Perot interferometry constitutes an effective technique for the detection and identification of proplyds. Some of the proplyds and proplyd candidates become noticeable only after data processing of the Fabry-Perot velocity cubes. In addition, we present the H II region subtracted radial velocity profiles of most of the identified proplyds (13) and proplyd candidates (3). We estimate from these profiles their main kinematic properties. We find that all of them have velocities redshifted relative to the Orion nebular emission. The studied proplyds show typical values of mass loss and disk lifetimes and we discuss the implications of these values, taking into account the fact that this study is done over a large quantity of proplyds. Finally, we find that our velocity profiles suggest that a large fraction of proplyds have monopolar microjets.
