ALMA reveals the coherence of the magnetic field geometry in OH 231.8+4.2
L. Sabin, R. Sahai, W. H. T. Vlemmings +7
In a continuing effort to investigate the role of magnetic fields in evolved low and intermediate mass stars (principally regarding the shaping of their envelopes), we present new…
Large-scale structures in high Reynolds number rotating Waleffe flow
Shafqat Farooq, Martin Huarte-Espinosa, Rodolfo Ostilla-Mónico
We perform direct numerical simulations of rotating turbulent Waleffe flow, the flow between two parallel plates with a sinusoidal streamwise shear driving force, to study the form…
Models of the Hydrodynamic Histories of post-AGB Stars. I. Multiflow Shaping of OH231.8+04.2
Bruce Balick, Adam Frank, Baowei Liu +1
We present a detailed hydrodynamic model that matches the present structure of the well-observed preplanetary nebula OH231.8+04.2. The purpose of the model is to present a physical…
Size of discs formed by wind accretion in binaries can be underestimated if the role of wind-driving force is ignored
Eric G. Blackman, Jonathan J. Carroll-Nellenback, Adam Frank +2
Binary systems consisting of a secondary accreting form a wind-emitting primary are ubiquitous in astrophysics. The phenomenology of such Bondi-Hoyle-Lyttleton (BHL) accretors is p…
Outflows from Evolved Stars: The Rapidly Changing Fingers of CRL618
Bruce Balick, Martín Huarte-Espinosa, Adam Frank +4
Our ultimate goal is to probe the nature of the collimator of the outflows in the pre PN CRL618. CRL618 is uniquely suited for this purpose owing to its multiple, bright, and caref…
Mass loading and knot formation in AGN jets by stellar winds
Martin Huarte-Espinosa, Eric G. Blackman, Alex Hubbard +1
Jets from active galaxies propagate from the central black hole out to the radio lobes on scales of hundreds of kiloparsecs. The jets may encounter giant stars with strong stellar…
The Formation and Evolution of Wind-Capture Disks In Binary Systems
Martin Huarte-Espinosa, Jonathan Carroll-Nellenback, Jason Nordhaus +2
We study the formation, evolution and physical properties of accretion disks formed via wind capture in binary systems. Using the AMR code AstroBEAR, we have carried out high resol…
Comparing Poynting flux dominated magnetic tower jets with kinetic-energy dominated jets
Martín Huarte-Espinosa, Adam Frank, Eric G. Blackman +4
Magnetic Towers represent one of two fundamental forms of MHD outflows. Driven by magnetic pressure gradients, these flows have been less well studied than magneto-centrifugally la…
On the structure and stability of magnetic tower jets
Martín Huarte-Espinosa, Adam Frank, Eric G. Blackman +4
Modern theoretical models of astrophysical jets combine accretion, rotation, and magnetic fields to launch and collimate supersonic flows from a central source. Near the source, ma…
Magnetic Towers and Binary-Formed Disks: New Results for PN Evolution
Martín Huarte-Espinosa, Adam Frank
We present new results of 3-D AMR MHD simulations focusing on two distinct aspects of PPN evolution. We first report new simulations of collimated outflows driven entirely by magne…
Laboratory experiments and simulations on jets
Martín Huarte-Espinosa, Adam Frank, Eric Blackman
Astrophysical jets have been studied with observations, theoretical models and numerical simulations for decades. Recently, supersonic magnetized jets have been formed in laborator…
Modeling Poynting flux vs. kinetic-energy dominated jets
Martín Huarte-Espinosa, Adam Frank, Eric G. Blackman
We present 3D-MHD AMR simulations of Poynting flux dominated (PFD) jets formed by injection of magnetic energy. We compare their evolution with a hydrodynamic jet which is formed b…
Interaction of Fanaroff-Riley class II jets with a magnetised intra-cluster medium
Martín Huarte-Espinosa, Martin Krause, Paul Alexander
We present 3-D MHD and synthetic numerical simulations to follow the evolution of randomly magnetized intra-cluster medium plasma under the effects of powerful, light, hypersonic a…
Interaction of Fanaroff-Riley class II radio jets with a randomly magnetised intra-cluster medium
Martín Huarte-Espinosa, Martin Krause, Paul Alexander
A combination of three-dimensional (3D) magnetohydrodynamics (MHD) and synthetic numerical simulations are presented to follow the evolution of a randomly magnetised plasma that mo…
From Bipolar to Elliptical: Simulating the Morphological Evolution of Planetary Nebulae
Martín Huarte-Espinosa, Adam Frank, Bruce Balick +4
The majority of Proto-planetary nebulae (PPN) are observed to have bipolar morphologies. The majority of mature PN are observed to have elliptical shapes. In this paper we address…
Three-dimensional magnetohydrodynamic simulations of the evolution of magnetic fields in Fanaroff-Riley class II radio sources
Martin Huarte-Espinosa, Martin Krause, Paul Alexander
Radio observations of Fanaroff-Riley class II sources often show correlations between the synchrotron emission and the linear-polarimetric distributions. Magnetic position vectors…
Modelling magnetically dominated and radiatively cooling jets
Martin Huarte-Espinosa, Adam Frank, Eric Blackman
Using 3D-MHD Eulerian-grid numerical simulations, we study the formation and evolution of rising magnetic towers propagating into an ambient medium. The towers are generated from a…
