HST-Scale 3D simulations of MHD disc winds : A rotating two-component jet structure
Jan Staff, Nico Koning, Rachid Ouyed +2
We present the results of large scale, three-dimensional magneto-hydrodynamics simulations of disc-winds for different initial magnetic field configurations. The jets are followed…
The puzzling early detection of low velocity 56Ni decay lines in SN 2014J: Hints of a compact remnant
Rachid Ouyed, Denis Leahy, Nico Koning +1
We show that the low-velocity 56Ni decay lines detected earlier than expected in the type Ia SN 2014J find an explanation in the Quark-Nova Ia model which involves the thermonuclea…
Towards Non-spherical Radio Models
Valério A. R. M. Ribeiro, Wolfgang Steffen, Laura Chomiuk +3
Radio observations of novae in outburst are of particular interest due to the physical parameters that may be retrieved from fitting the radio light curves. Most models that have f…
Radio Frequency Models of Novae in eruption. I. The Free-Free Process in Bipolar Morphologies
V. A. R. M. Ribeiro, L. Chomiuk, U. Munari +6
Observations of novae at radio frequencies provide us with a measure of the total ejected mass, density profile and kinetic energy of a nova eruption. The radio emission is typical…
Hints of a second explosion (a quark nova) in Cassiopeia A Supernova
Rachid Ouyed, Denis Leahy, Nico Koning
We show that the explosive transition of the neutron star (NS) to a quark star (QS) (a Quark Nova) in Cassiopeia A (Cas A) a few days following the SN proper can account for severa…
r-Java 2.0: the astrophysics
M. Kostka, N. Koning, Z. Shand +2
[Context:] This article is the second in a two part series introducing r-Java 2.0, a nucleosynthesis code for open use that performs r-process calculations and provides a suite of…
