Disk and wind interaction in the young stellar object MWC 297 spatially resolved with VLTI/AMBER
F. Malbet, M. Benisty, W. J. De Wit +15
The young stellar object MWC 297 has been observed with the VLT interferometer equipped with the AMBER instrument. MWC 297 has been spatially resolved in the continuum with a visib…
A substellar companion around the intermediate-mass giant star HD 11977
J. Setiawan, J. Rodmann, L. da Silva +6
We report the discovery of a substellar companion to the intermediate-mass star HD 11977 (G5 III). Radial velocities of this star have been monitored for five years with FEROS at t…
Dynamics of the Solar Magnetic Network: Two-dimensional MHD Simulations
S. S. Hasan, A. A. van Ballegoiijen, W. Kalkofen +1
The aim of this work is to identify the physical processes that occur in the network and contribute to its dynamics and heating. We model the network as consisting of individual fl…
Carbon monoxide in the solar atmosphere I. Numerical method and two-dimensional models
S. Wedemeyer-Boehm, I. Kamp, J. Bruls +1
The radiation hydrodynamic code CO5BOLD has been supplemented with the time-dependent treatment of chemical reaction networks. Advection of particle densities due to the hydrodynam…
Forward modeling of stellar coronae: from a 3D MHD model to synthetic EUV spectra
H. Peter, B. V. Gudiksen, A. Nordlund
A forward model is described in which we synthesize spectra from an ab-initio 3D MHD simulation of an outer stellar atmosphere, where the coronal heating is based on braiding of ma…
Radiative transfer in decomposed domains
T. Heinemann, W. Dobler, A. Nordlund +1
An efficient algorithm for calculating radiative transfer on massively parallel computers using domain decomposition is presented. The integral formulation of the transfer equation…
