Bondi-Hoyle-Littleton accretion and the upper mass stellar IMF
Javier Ballesteros-Paredes, Lee W. Hartmann, Nadia Perez-Goytia +1
We report on a series of numerical simulations of gas clouds with self-gravity forming sink particles, adopting an isothermal equation of state to isolate the effects of gravity fr…
The number fraction of discs around brown dwarfs in Orion OB1a and the 25 Orionis group
Juan José Downes, Carlos Román-Zúñiga, Javier Ballesteros-Paredes +7
We present a study of 15 new brown dwarfs belonging to the Myr old 25 Orionis group and Orion OB1a sub-association with spectral types between M6 and M9 and estimated masse…
The Gould's Belt Very Large Array Survey II: The Serpens region
Gisela N. Ortiz-León, Laurent Loinard, Amy J. Mioduszewski +12
We present deep (Jy) radio continuum observations of the Serpens molecular cloud, the Serpens south cluster, and the W40 region obtained using the Very Large Array in it…
Are protoplanetary disks born with vortices? -- Rossby wave instability driven by protostellar infall
Jaehan Bae, Lee Hartmann, Zhaohuan Zhu
We carry out two-fluid, two-dimensional global hydrodynamic simulations to test whether protostellar infall can trigger Rossby wave instability (RWI) in protoplanetry disks. Our re…
