X-shooter observations of accretion and outflows in young stellar objects | Beate Stelzer (INAF-Osservatorio Astronomico di Palermo)

I present broad-band (350-2500nm) mid-resolution X-Shooter/VLT spectra of three accreting young stellar objects with spectral types between M5 and M8, i.e. near or within the brown dwarf regime. These observations provide a rich database of accretion diagnostics from the Br$\gamma$ and Pa$\beta$ lines in the near-IR to the Balmer jump in the UV including the full optical band with the Balmer series and He\,$\lambda$5876 and the Ca\,IRT. Finally, outflows can be traced through forbidden line emission. In this talk I focus on three of the most interesting targets from our survey: (1) FU\,Tau\,A, overluminous in the HR diagram with respect to predictions of pre-main sequence evolutionary models; (2) TWA-27 (alias 2M1207-39), the planet-hosting prototype for an accreting brown dwarf; (3) Par-Lup3-4, a young stellar object with edge-on disk driving a jet.
