2D Spectroscopy of HH588 Large-Scale Outflow (original) (raw)

Abstract

The HH588 flow is studied with multi-pupil spectrograph on the 2.6 m telescope of Byurakan observatory. The bright components of this flow are analyzed, using the maps of emission lines and radial velocities. The bipolar nature of this outflow is obvious from their radial velocities. The unusual feature of HH588 flow is its inclusion in the bright-rimmed cloud; thus, it can belong to so-called irradiated jets. It is worth to mention that all HH-objects studied here show a deceleration in the regions of interaction with the interstellar medium.
