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…
Discovery of X rays from Class 0 protostar candidates in OMC-3
Yohko Tsuboi, Katsuji Koyama, Kenji Hamaguchi +4
We have observed the Orion Molecular Clouds 2 and 3 (OMC-2 and OMC-3) with the Chandra X-ray Observatory (CXO). The northern part of OMC-3 is found to be particularly rich in new X…
The Formation of Brown Dwarfs as Ejected Stellar Embryos
Bo Reipurth, Cathie Clarke
We conjecture that brown dwarfs are substellar objects because they have been ejected from small newborn multiple systems which have decayed in dynamical interactions. In this view…
