Masses and envelope binding energies of primary stars at the onset of a common envelope
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We present basic properties of primary stars that initiate a common envelope (CE) in a binary, while on the giant branch. We use the population-synthesis code described in Politano et al. (2010) and f...
Brown Dwarf Jets: Investigating the Universality of Jet Launching Mechanisms at the Lowest Masses
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Recently it has become apparent that proto-stellar-like outflow activity extends to the brown dwarf (BD) mass regime. While the presence of accretion appears to be the common ingredient in all objects...
