Protostellar Outflows and Radiative Feedback from Massive Stars. II. Feedback, Star Formation Efficiency, and Outflow Broadening
Rolf Kuiper, Neal J. Turner, Harold W. Yorke
We perform two-dimensional axially symmetric radiation-hydrodynamic simulations to assess the impact of outflows and radiative force feedback from massive protostars by varying whe…
On the existence of accretion-driven bursts in massive star formation
D. M. -A. Meyer, E. I. Vorobyov, R. Kuiper +1
Accretion-driven luminosity outbursts are a vivid manifestation of variable mass accretion onto protostars. They are known as the so-called FU Orionis phenomenon in the context of…
Propagation of Relativistic, Hydrodynamic, Intermittent Jets in a Rotating, Collapsing GRB Progenitor Star
Jin-Jun Geng, Bing Zhang, Rolf Kuiper
The prompt emission of gamma-ray bursts (GRBs) is characterized by rapid variabilities, which may be a direct reflection of the unsteady central engine. We perform a series of axis…
Simulating the Formation of Massive Protostars: I. Radiative Feedback and Accretion Disks
Mikhail Klassen, Ralph Pudritz, Rolf Kuiper +2
We present radiation hydrodynamic simulations of collapsing protostellar cores with initial masses of 30, 100, and 200 M. We follow their gravitational collapse and the f…
Composite biasing in Monte Carlo radiative transfer
Maarten Baes, Karl D. Gordon, Tuomas Lunttila +4
Biasing or importance sampling is a powerful technique in Monte Carlo radiative transfer, and can be applied in different forms to increase the accuracy and efficiency of simulatio…
Dynamical friction for supersonic motion in a homogeneous gaseous medium
Daniel Thun, Rolf Kuiper, Franziska Schmidt +1
The supersonic motion of gravitating objects through a gaseous medium constitutes a classical problem in theoretical astrophysics. Its application covers a broad range of objects a…
