Not to appear in Nonlearned J., 45. Spatially Resolved Observations of the Bipolar Optical Outflow from the Brown Dwarf 2MASSJ12073347-3932540. 1 E.T. Whelan2,3

Studies of brown dwarf (BD) outflows provide information pertinent to questions on BD formation, as well as allowing outflow mechanisms to be investigated at the lowest masses. Here new observations of the bipolar outflow from the 24 MJUP BD, 2MASSJ12073347-3932540 are presented. The outflow was originally identified through the spectro-astrometric analysis of the [OI]λ6300 emission line. Follow-up observations consisting of spectra and [SII], R-band and I-band images were obtained. The new spectra confirm the original results and are used to constrain the outflow PA at ∼ 65◦. The [OI]λ6300 emission line region is spatially resolved and the outflow is detected in the [SII] images. The detection is firstly in the form of an elongation 1Based on data collected by UVES (281.C-5025(A)) and FORS1 (380.C-0412(A)) observations at the VLT on Cerro Paranal (Chile) which is operated by the European Southern Observatory (ESO). Data collected from the ESO archive (071.C-0432(A), 085.C0238(A), 078.C-0158(A, B)) is also used in the analysis presented here
