Losing energy via EM, G field

  1. Mar 21, 2008 #1
    I miss sometimes the most basic things in physics. (I think they are basic). For example, recent reading about stars in space made me wonder about few things...

    1. stars seem to lose energy if they rotate, via magnetic field (eg. neutron stars)
    "The energy emitted by common pulsars has its origin in the slowing down of their rotation" (10^8 - 10^11 T)
    "The magnetic filed around a rotating neutron star carries plasma with it. At a certain distance the speed of plasma approaches the speed of light. At this distance the radiating regions emit radiation in a narrow forward beam"

    2. "Binary systems lose energy by gravitational radiation, and eventually the two components should merge"
