Magnetospheric outflows in young stellar objects

EPJ Web of Conferences, 2014
Different classes of outflows are associated with the magnetospheric activity of accreting T Tauri protostars. Stellar winds are accelerated along the open field lines anchored in the stellar surface; disk winds (extended or X-type) can be launched along

Observational Signatures of AGN Feedback in the Morphology and the Ionization States of Milky Way-like Galaxies

The Astrophysical Journal
We make an in-depth analysis of different active galactic nuclei (AGN) jet models’ signatures, inducing quiescence in galaxies with a halo mass of 10 ^12 M _⊙ .

Probing the Structure of Jet Driven Core-Collapse Supernova and Long Gamma Ray Burst Progenitors with High Energy Neutrinos

, 2012
Times of arrival of high energy neutrinos encode information about their sources. We demonstrate that the energy-dependence of the onset time of neutrino emission in advancing relativistic jets can be used to extract important information about the ...

Events in the life of a cocoon surrounding a light, collapsar jet

, 2002
According to the collapsar model, gamma-ray bursts are thought to be produced in shocks that occur after the relativistic jet has broken free from the stellar envelope.

Compact Stellar Jets

, 2019
Jets produced by compact stars are the ideal laboratories for understanding jets in general due to the ability to measure accretors properties accurately, and the short timescales of variability of the systems. We outline what is needed to move forward with understanding jet production in X-ray binaries.

Gamma Rays from Compton Scattering in the Jets of Microquasars: Application to LS 5039

, 2005
Recent HESS observations show that microquasars in high-mass systems are sources of VHE gamma-rays. A leptonic jet model for microquasar gamma-ray emission is developed.

Helical Magnetic Field in a Massive Protostellar Jet

The Astrophysical Journal Letters
Highly collimated outflows (jets) are observed across a wide range of astrophysical systems involving the accretion of material onto central objects, from supermassive black holes in active galaxies to proto-brown dwarfs and stellar-mass black holes ...

Phenomenological Analogies in Black Hole Systems of all Masses

, 2004
I review the progress made on the physics of relativistic jets from black hole systems in the context of the analogy between AGN and microquasars that was proposed one decade ago.

Jet-shaped filamentary ejecta in common envelope evolution

The Open Journal of Astrophysics
We conduct three-dimensional (3D) hydrodynamical simulations of common envelope evolution (CEE) of a neutron star (NS) that launches jets as it spirals in inside the envelope of a rotating red supergiant (RSG) stellar envelope and find that Rayleigh ...

Planetary nebula progenitors that swallow binary systems

, 2015
I propose that some irregular `messy' planetary nebulae owe their morphologies to triple-stellar evolution where tight binary systems evolve inside and/or on the outskirts the envelope of asymptotic giant branch (AGB) stars.
