Brown Dwarfs as Ejected Stellar Embryos: Observational Perspectives
Bo Reipurth, Cathie Clarke
We discuss a scenario in which brown dwarfs are formed like stars, except that their full collapse phases are interrupted through dynamical interactions in small multiple systems,…
Kinematics of the HH 111 jet from STIS spectra
A. C. Raga, A. Noriega-Crespo, B. Reipurth +4
We present a long-slit spectrum of the Herbig-Haro object HH 111, obtained with SITS on the Hubble Space Telescope. This spectrum has a spectral resolution of approx. 50 km/s, so i…
A Dynamical Origin for Brown Dwarfs
Bo Reipurth, Cathie Clarke, Eduardo Delgado-Donate
Brown dwarfs may have such low masses because they are prematurely ejected from small unstable multiple systems, while the members are still actively building up their masses. We d…
The outburst of the T Tauri star EX Lupi in 1994
Thomas Lehmann, Bo Reipurth, Wolfgang Brandner
We have observed an outburst of the T Tauri star EX Lup in March 1994. We present both photometric (BVR) and spectroscopic (low and medium resolution) observations carried out duri…
