We study explosions of stellar models using a one-dimensional Lagrangian hydrodynamics code. We calculate how much mass is liberated as a function of the energy of explosion for a variety of pre-explosion polytropic structures and for equations of state with a range of radiation-to-gas pressure ratios. The results show that simple assumptions about the amount of mass lost in an explosion can be quite inaccurate, and that even one-dimensional stellar models exhibit a rich phenomenology. The mass… Expand
Shock Dynamics in Stellar Outbursts: I. Shock formation
Wave-driven outflows and non-disruptive explosions have been implicated in pre-supernova outbursts, supernova impostors, LBV eruptions, and some narrow-line and superluminous supernovae. To modelExpand
Shock Emergence in Supernovae: Limiting Cases and Accurate Approximations
We examine the dynamics of accelerating normal shocks in stratified planar atmospheres, providing accurate fitting formulae for the scaling index relating shock velocity to the initial density andExpand
Oblique Shock Breakout in Supernovae and Gamma-Ray Bursts. II. Numerical Solutions for Non-relativistic Pattern Speeds
Non-spherical explosions develop non-radial flows as the pattern of shock emergence progresses across the stellar surface. In supernovae, these flows can limit ejecta speeds, stifle shock breakoutExpand
Partial stellar explosions – ejected mass and minimal energy
Many massive stars appear to undergo enhanced mass loss during late stages of their evolution. In some cases, the ejected mass likely originates from non-terminal explosive outbursts, rather thanExpand
Wave-driven Shocks in Stellar Outbursts: Dynamics, Envelope Heating, and Nascent Blast Waves
We address the shocks from acoustic pulses and wave trains in general one-dimensional flows, with an emphasis on the application to super-Eddington outbursts in massive stars. Using approximateExpand


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
Supernovae, Jets, and Collapsars
We continue our study of the possible production of supernovae and a variety of high-energy transients by black hole formation in massive stars endowed with rotation: the "collapsar model." The blackExpand
Neutron Star Accretion in a Supernova
An estimate can be made of the effect of a central mass on an explosion through the study of self-similar blast waves in a medium having an inverse-square-of-r density profile, as is approximatelyExpand
The Evolution and Explosion of Massive Stars. II. Explosive Hydrodynamics and Nucleosynthesis
The nucleosynthetic yield of isotopes lighter than A = 66 (zinc) is determined for a grid of stellar masses and metallicities including stars of 11, 12, 13, 15, 18, 19, 20, 22, 25, 30, 35, and 40Expand
The runaway black hole GRO J1655-40 ⋆
We have used the Hubble Space Telescope to measure the motion in the sky and compute the galactocentric orbit of the black hole X-ray binary GRO J1655-40. The system moves with a runaway spaceExpand
Theoretical black hole mass distributions
We derive the theoretical distribution function of black hole masses by studying the formation processes of black holes. We use the results of recent two-dimensional simulations of stellar coreExpand
The mass of x-ray Nova Scorpii 1994 GRO J1655-40
The radial velocity curve of the secondary star is measured and a semi-amplitude of K2 is obtained, which reduces the binary mass function to f(M) = 2.73 ± 0.09 M⊙. Expand
Evidence of a supernova origin for the black hole in the system GRO J1655 - 40
Stars with masses greater than about ten solar masses are thought to end their lives either in a supernova or in a direct gravitational collapse process, either of which could have a black hole as aExpand
Optical Observations of GRO J1655?40 in Quiescence. I. A Precise Mass for the Black Hole Primary
We report photometric and spectroscopic observations of the black hole binary GRO J1655-40 in complete quiescence. In contrast to the 1995 photometry, the light curves from 1996 are almost completelyExpand
