GMOS-IFU observations of LV2

Abstract

We present GMOS-IFU spectroscopic observations of the proplyd 167-317 (LV2) near the Trapezium cluster in the Orion nebula, obtained at the Gemini South Observatory. The proplyd was observed in optical wavelengths ranging from ∼ 5515 Å to ∼ 7630Å. The ionized photo-evaporated flow was detected together with a microjet and possibly the blue-shifted jet that appear in most of the detected emission lines as multiple peaks at different velocities. Typically, there is a low velocity peak at ∼ 30 km s-1, a high velocity red-shifted peak at ∼ 100 km s-1 and a very faint blue-shifted peak at ∼ -60 km s-1. The observations also allowed us to determine spatially the emitting regions. The red-shifted jet is located to the SE of the central emission. We find evidences that the red-shifted jet has a variable velocity, which slowly drops with increasing distance from the proplyd © 2007 Springer-Verlag Berlin Heidelberg.
