Relativistic stellar jets: dynamics and non-thermal radiation [PDF]
EPJ Web of Conferences, 2013 Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.

Influence of protostellar jets and HII regions on the formation and evolution of stellar clusters [PDF]
Astronomy and Astrophysics, 2022 Context. Understanding the conditions in which stars and stellar clusters form is of great importance. In particular the role that stellar feedback may have is still hampered by large uncertainties. Aims.

Radio jets from young stellar objects [PDF]
The Astronomy and Astrophysics Review, 2018 Jets and outflows are ubiquitous in the process of formation of stars since outflow is intimately associated with accretion. Free–free (thermal) radio continuum emission in the centimeter domain is associated with these jets.

A search for ionized jets towards massive young stellar objects [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 Radio continuum observations using the Australia telescope compact array at 5.5, 9.0, 17.0 and 22.8 GHz have detected free-free emission associated with 45 of 49 massive young stellar objects and HII regions.

Scaling stellar jets to the laboratory: The power of simulations [PDF]
Laser and Particle Beams, 2009 Advances in laser and Z-pinch technology, coupled with the development of plasma diagnostics, and the availability of high-performance computers, have recently stimulated the growth of high-energy density laboratory astrophysics.

Magnetic Fields in Stellar Jets [PDF]
The Astrophysical Journal, 2007 Although several lines of evidence suggest that jets from young stars are driven magnetically from accretion disks, existing observations of field strengths in the bow shocks of these flows imply that magnetic fields play only a minor role in the ...

Diagnostics of inhomogeneous stellar jets - Convolution effects and data reconstruction [PDF]
Astronomy & Astrophysics, 2008 Context. In the interpretation of stellar jet observations, the physical parameters are usually determined from emission line ratios, obtained from spectroscopic observations or using the information contained in narrow band images.

Monthly Notices of the Royal Astronomical Society, 1987 This paper contains some results of axisymmetric numerical calculations of the shock structures in steady supersonic jets in which there is significant radiative cooling. We find that the regularly spaced shock cells found in adiabatic jets still occur and that cooling can by itself induce shocks if it is fast enough.

Stellar jets with intrinsically variable sources
Astrophysical Journal, 1990 Models for high Mach number, isothermal, pressure-matched jets ejected from sources with variable velocities are presented. It is found that the relaxation of the assumption of a time-independent source allows the complex position-velocity diagrams and multiple bow shock structures observed in some stellar jets to be explained in a straightforward way.

Interaction of young stellar object jets with their accretion disk [PDF]
Astronomy and Astrophysics, 2005 I reexamine recent observations of velocity profiles across jets blown by young stellar objects, and argue that the observations do not support the interpretation of jets rotating around their symmetry axes. Instead, I propose that the interaction of the jets with a twisted-tilted (wrapped) accretion disk can form the observed asymmetry in the jets ...
