The Radial Velocity Profiles of some Proplyds in the Orion Nebula

We use H scanning Fabry-Perot interferometric data on the Orion Nebulain order to study the proplyds of the central region. We find that Fabry-Perotinterferometry constitutes an effective technique for the detection and identificationof proplyds. Some of the proplyds and proplyd candidates become no...
