Shape and evolution of wind-blown bubbles of massive stars: on the effect of the interstellar magnetic field
Allard Jan van Marle, Zakaria Meliani, Alexandre Marcowith
The winds of massive stars create large (>10 pc) bubbles around their progenitors. As these bubbles expand they encounter the interstellar coherent magnetic field which, depending…
Eyes in the sky: Interactions between AGB winds and the interstellar magnetic field
A. J. van Marle, N. L. J. Cox, L. Decin
We aim to examine the role of the interstellar magnetic field in shaping the extended morphologies of slow dusty winds of Asymptotic Giant-branch (AGB) stars in an effort to pin-po…
Using numerical models of bow shocks to investigate the circumstellar medium of massive stars
Allard Jan van Marle, Leen Decin, Nick Cox +1
Many massive stars travel through the interstellar medium at supersonic speeds. As a result they form bow shocks at the interface between the stellar wind. We use numerical hydrody…
Can the magnetic field in the Orion arm inhibit the growth of instabilities in the bow shock of Betelgeuse?
Allard Jan van Marle, Leen Decin, Zakaria Meliani
Many evolved stars travel through space at supersonic velocities, which leads to the formation of bow shocks ahead of the star where the stellar wind collides with the interstellar…
Pulsating red giant stars in eccentric binary systems discovered from Kepler space-based photometry
P. G. Beck, K. Hambleton, J. Vos +30
The unparalleled photometric data obtained by NASA's Kepler space telescope led to an improved understanding of red giant stars and binary stars. Seismology allows us to constrain…
A hydrodynamical model of the circumstellar bubble created by two massive stars
Allard Jan van Marle, Zakaria Meliani, Alexandre Marcowith
Numerical models of the wind-blown bubble of massive stars usually only account for the wind of a single star. However, since massive stars are usually formed in clusters, it would…
Dust distribution in circumstellar shells
Allard Jan van Marle, Zakaria Meliani, Rony Keppens +1
We present numerical simulations of the hydrodynamical interactions that produce circumstellar shells. These simulations include several scenarios, such as wind-wind interaction an…
On the circumstellar medium of massive stars and how it may appear in GRB observations
Allard Jan van Marle, Rony Keppens, Sung-Chul Yoon +1
Massive stars lose a large fraction of their original mass over the course of their evolution. These stellar winds shape the surrounding medium according to parameters that are the…
Formation of Solar Filaments by Steady and Nonsteady Chromospheric Heating
C. Xia, P. F. Chen, R. Keppens +1
It has been established that cold plasma condensations can form in a magnetic loop subject to localized heating of the footpoints. In this paper, we use grid-adaptive numerical sim…
