X-ray illumination of the ejecta of Supernova 1987A

J. Larsson, C. Fransson, G. Östlin +25

We present the late-time optical light curve of the ejecta of SN 1987A measured from HST imaging observations spanning the past 17 years. We find that the flux from the ejecta decl…

Warm water vapour in the sooty outflow from a luminous carbon star

L. Decin, M. Agundez, M. J. Barlow +34

In 2001, the discovery of circumstellar water vapour around the ageing carbon star IRC+10216 was announced. This detection challenged the current understanding of chemistry in old…

The properties of SN Ib/c locations

G. Leloudas, A. Gallazzi, J. Sollerman +7

Aims: To gain better insight on the physics of stripped-envelope core-collapse supernovae through studying their environments. Methods: We obtained low-resolution optical spectrosc…

Simulations of astrophysical dynamos

Axel Brandenburg

Numerical aspects of dynamos in periodic domains are discussed. Modifications of the solutions by numerically motivated alterations of the equations are being reviewed using the ex…

Plasmoid ejections driven by dynamo action underneath a spherical surface

Jörn Warnecke, Axel Brandenburg, Dhrubaditya Mitra

We present a unified three-dimensional model of the convection zone and upper atmosphere of the Sun in spherical geometry. In this model, magnetic fields, generated by a helically…

Dissipation in dynamos at low and high magnetic Prandtl numbers

A. Brandenburg

Using simulations of helically driven turbulence, it is shown that the ratio of kinetic to magnetic energy dissipation scales with the magnetic Prandtl number in power law fashion…
