    • Abstract


      We make a toy model for M87 jet to interpret its parabolic structure and acceleration in the apparent speeds, according to observations in milli-arcsecond to arcsecond scales upstream of HST-1. The outermost layer of jet is driven by the frame-dragging effect in the Kerr spacetime with a slowly to moderately spinning black hole. The corresponding magnetosphere has a foot-point 𝑅0 in the vicinity of event-horizon, and rotating at a frequency 𝛺F equal to that of the frame-dragging 𝜔(𝑅0).

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
