Low- and High-energy Neutrinos from SN 2023ixf in M101
The Astrophysical Journal Letters, 2023 Supernova (SN) 2023ixf in M101 is the closest SN explosion observed in the last decade. Therefore, it is a suitable test bed to study the role of jets in powering the SN ejecta.

Bipolar Outflows and Stellar Jets [PDF]
Symposium - International Astronomical Union, 1987 A wealth of data is now available on the energetic mass outflows that are associated with young stellar objects. This phenomenon is thought to occur at a very early stage in the evolution of stars of almost all masses. The discovery of this energetic event was first made through observations of the rapidly expanding molecular gas that surrounds many of

Cosmic Feedback from AGN [PDF]
, 2009 Accretion onto the massive black hole at the centre of a galaxy can feed energy and momentum into its surroundings via radiation, winds and jets. Feedback due to radiation pressure can lock the mass of the black hole onto the M-sigma relation, and shape ...

Braking down an accreting protostar: disc-locking, disc winds, stellar winds, X-winds and Magnetospheric Ejecta [PDF]
, 2013 Classical T Tauri stars are low mass young forming stars that are surrounded by a circumstellar accretion disc from which they gain mass. Despite this accretion and their own contraction that should both lead to their spin up, these stars seem to ...

Simulations of Gamma-Ray Emission from Magnetized Microquasar Jets
Advances in High Energy Physics, 2018 In this work, we simulate γ-rays created in the hadronic jets of the compact object in binary stellar systems known as microquasars. We utilize as the main computational tool the 3D relativistic magnetohydrodynamical code PLUTO combined with in-house ...

Theory of Stellar and Extragalactic Jets [PDF]
International Astronomical Union Colloquium, 1986 AbstractDifferent types of astrophysical jets are briefly described and the wide differences in their observed properties are emphasized. Various physical mechanisms that have been proposed for creating jets, based on gas dynamical, magnetic, and radiative stresses are briefly reviewed. It is argued that magnetic fields are probably generally important

Diagnostics of inhomogeneous stellar jets [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. The basic hypothesis in the interpretation of the observations is that the emitting region is homogeneous along the line ...

The Angular Momenta of Neutron Stars and Black Holes as a Window on Supernovae [PDF]
, 2011 It is now clear that a subset of supernovae display evidence for jets and are observed as gamma-ray bursts. The angular momentum distribution of massive stellar endpoints provides a rare means of constraining the nature of the central engine in core ...

Steady, partially ionized stellar jets
The Astrophysical Journal, 1990 Un modele de jet stellaire stationnaire a symetrie cylindrique non-adiabatique de nombre de Mach eleve, qui inclut les effets de l'ionisation hors-equilibre et du refroidissement, est developpe. Les caracteristiques generales de ces jets sont decrites et leurs implications pour l'interpretation des jets observes analysees.

Hypersonic jets in astrophysical conditions: focus on spreading and asymmetric stability properties
New Journal of Physics, 2014 High Mach number jets emanating from young stars show remarkable collimation, low opening angle and resilience against the growth of instabilities, especially the asymmetric ones. In recent laboratory experiments instances of asymmetric three-dimensional
