The expulsion of stellar envelopes in core-collapse supernovae
We examine the relation between presupernova stellar structure and the distribution of ejecta in core-collapse supernovae of Types Ib, Ic, and II, under the approximations of adiabatic, sphericallyExpand

Efficiencies of Low-Mass Star and Star Cluster Formation
Using a quantitative model for bipolar outflows driven by hydromagnetic protostellar winds, we calculate the efficiency of star formation assuming that available gas is either converted into stars orExpand

Trans-Relativistic Blast Waves in Supernovae as Gamma-Ray Burst Progenitors
We investigate the acceleration of shock waves to relativistic velocities in the outer layers of exploding stars. By concentrating the energy of the explosion in the outermost ejecta, suchExpand

THE DYNAMICS OF RADIATION-PRESSURE-DOMINATED H II REGIONS
We evaluate the role of radiation pressure in the dynamics of H II regions. We first determine under what conditions radiation pressure is significant in comparison to gas pressure and show that,Expand

Supernova hosts for gamma-ray burst jets: dynamical constraints
I constrain a possible supernova origin for gamma-ray bursts (GRBs) by modelling the dynamical interaction between a relativistic jet and a stellar envelope surrounding it. The delay in observer timeExpand

On the Role of Massive Stars in the Support and Destruction of Giant Molecular Clouds
We argue that massive stars are the dominant sources of energy for the turbulent motions within giant molecular clouds and that the primary agent of feedback is the expansion of H II regions withinExpand

On the Role of Disks in the Formation of Stellar Systems: A Numerical Parameter Study of Rapid Accretion
We study rapidly accreting, gravitationally unstable disks with a series of idealized global, numerical experiments using the code ORION. Our numerical parameter study focuses on protostellar disks,Expand

STELLAR FEEDBACK IN MOLECULAR CLOUDS AND ITS INFLUENCE ON THE MASS FUNCTION OF YOUNG STAR CLUSTERS
We investigate how the removal of interstellar material by stellar feedback limits the efficiency of star formation in molecular clouds and how this determines the shape of the mass function of youngExpand

Lithium Depletion in Fully Convective Pre-Main-Sequence Stars
We present an analytic calculation of the thermonuclear depletion of lithium in contracting, fully con- vective, preEmain-sequence stars of mass Previous numerical work relies on still uncertain M (Expand

Protostellar Outflow-driven Turbulence
Protostellar outflows crisscross the regions of star cluster formation, stirring turbulence and altering the evolution of the forming cluster. We model the stirring of turbulent motions byExpand
