Magnetic Braking and Protostellar Disk Formation: Ambipolar Diffusion
Richard R. Mellon, Zhi-Yun Li
It is established that the formation of rotationally supported disks during the main accretion phase of star formation is suppressed by a moderately strong magnetic field in the id…
Magnetic Braking and Protostellar Disk Formation: The Ideal MHD Limit
Richard R. Mellon, Zhi-Yun Li
Magnetic fields are usually considered dynamically important in star formation when the dimensionless mass-to-flux ratio is close to, or less than, unity (lambda<~1). We show that,…
The Spatial, Ionization, and Kinematic Conditions of the z=1.39 Damped Ly-alpha Absorber in Q0957+561 A,B
Chris Churchill, Rick Mellon, Jane Charlton +1
We examined the sizes of the absorption clouds in a z=1.3911 damped Ly-alpha absorber (DLA) in the double image lensed quasar Q0957+561 A,B (separation 135 pc at the absorber redsh…
A Radio Survey for Linear and Circular Polarization in Low Luminosity Active Galactic Nuclei
Geoffrey C. Bower, Heino Falcke, Richard R. Mellon
We conducted a Very Large Array survey of eleven low luminosity active galactic nuclei for linear and circular polarization at 8.4 GHz. We detected circular polarization in one sou…
Detection of Circular Polarization in M81*
A. Brunthaler, G. C. Bower, H. Falcke +1
We report the detection of circular polarization in the compact radio jet of the nearby spiral galaxy M81 (M81*). The observations were made with the Very Large Array at 4.8 and 8.…
Discovery of Radio Emission from the Brown Dwarf LP944-20
E. Berger, S. Ball, K. M. Becker +12
Brown dwarfs are classified as objects which are not massive enough to sustain nuclear fusion of hydrogen, and are distinguished from planets by their ability to burn deuterium. Ol…
