Exploring the Grain Properties in the Disk of HL Tau with an Evolutionary Model
Carlos Tapia, Susana Lizano, Anibal Sierra +2
We model the ALMA and VLA millimeter radial profiles of the disk around HL Tau to constrain the properties of the dust grains. We adopt the disk evolutionary models of Lynden-Bell…
Angular momentum in bipolar outflows: dynamical evolutionary model
J. A. López-Vázquez, J. Cantó, S. Lizano
We model molecular outflows produced by the time dependent interaction between a stellar wind and a rotating cloud envelope in gravitational collapse, studied by Ulrich. We conside…
An analytical model of radial dust trapping in protoplanetary disks
Anibal Sierra, Susana Lizano, Enrique Macías +3
We study dust concentration in axisymmetric gas rings in protoplanetary disks. Given the gas surface density, we derived an analytical total dust surface density by taking into acc…
Flat Spectrum Radio Continuum Emission Associated with Eridani
Luis F. Rodriguez, Susana Lizano, Laurent Loinard +3
We present Very Large Array observations at 33.0 GHz that detect emission coincident with Eridani to within (0.2 AU at the distance of this star), with a positio…
