Journal ArticleDOI
Numerical simulations of type III planetary migration: III. Outward migration of massive planets
TL;DR: In this article, the authors present a numerical study of rapid, so-called type III migration for Jupitersized planets embedded in a protoplanetary disc, and study in detail its evolution and physics, concentrating on the structure of the corotation and circumplanetary regions, and processes for stopping migration.
Journal ArticleDOI
Fast Large-Scale Reionization Simulations
Rajat M. Thomas,Saleem Zaroubi,Benedetta Ciardi,Andreas H. Pawlik,Panagiotis Labropoulos,Vibor Jelić,Gianni Bernardi,Michiel A. Brentjens,A. G. de Bruyn,A. G. de Bruyn,Geraint Harker,Léon V. E. Koopmans,Garrelt Mellema,V. N. Pandey,Joop Schaye,Sarod Yatawatta +15 more
TL;DR: In this article, the authors present an efficient method to generate large simulations of the Epoch of Reionization (EoR) without the need for a full 3D radiative transfer code.
Journal ArticleDOI
Discovery of a double ring in the core of η Carinae
Sacha Hony,Carsten Dominik,Laurentius Waters,Vincent Icke,Garrelt Mellema,R. van Boekel,A. de Koter,P. M. Morris,M. J. Barlow,Pierre Cox,Hans-Ulrich Käufl +10 more
TL;DR: In this paper, the authors reported the discovery of a double ring structure in the waist of the nebula surrounding η Carinae, which is reminiscent of that seen in SN1987A and some planetary nebulae.
Journal Article
Special relativistic jet collimation by inertial confinement
Frits Eulderink,Garrelt Mellema +1 more
TL;DR: In this article, the relativistic extension of a Roe solver method for nonrelativistic flow is used to simulate the collimation of an initially spherical outflow by a thickened disk (i.e. collimation by inertial confinement).
