Next: Binary Radiopulsars with Black Up: Black Holes in Binaries Previous: Black Holes in Binaries . Two different types of stellar BH formation exist: (1) direct core collapse   of a massive star and (2) AIC of a NS. A BH of the first type presumably will have a mass comparable to that of the collapsing star and can be born both from a single star and in a binary system. ...

In 1755, Immanuel Kant had the remarkable insight that stars and planetary systems form by the gravitational collapse and rotational flattening of interstellar clouds. Later in the 18th century, Marquis Pierre Simon de Laplace refined Kant s idea by suggesting that planets condensed from rings produced at the edge of a contracting disk while the Sun formed at the center a picture thereafter known as the Nebular Hypothesis. ...

The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... That produces an extra resistance to the flow of current. ...
