Black-Hole-Powered Jets Forge Fuel Star Formation
2017/3/13
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a surprising connection between a supermassive black hole and the galaxy where it resides.Powerful radio jets ...
Formation and large-scale confinement of jets emitted by young stars finally elucidated

2014/10/30
An international team of scientists has succeeded in explaining the formation and propagation over astronomical distances of jetsof matter emitted by young stars—one of the most fascinating mysteries ...
Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae--colorful, glowing clouds of dust and gas. In recent decades,...
Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate
MHD, Stars: pre-main sequence, Stars: winds, outfl ows, Stars: mass-loss, Stars: rotation, ISM
2011/10/8
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to ...

Kinematical Diagrams for Conical Relativistic Jets
Blazars:general galaxies:active quasars jets nuclei radio continuum
2009/5/12
We present diagrams depicting the expected inter-dependences
of two key kinematical parameters of radio knots in the parsec-scale jets
of blazars, deduced from VLBI observations. The two parameters ...
