... measurements of ne to estimate the magnetic fields. Due to the vector product in Equation 1, only the magnetic field component along the line-of-sight is measured, so the results depend on the assumed magnetic field topology. Most extragalactic radio sources exhibit Faraday rotation measures (RMs) o ...

IRIS observations of the solar transition region
... a cadence of 54 s and is an example of a fairly longlived “nest” of loops that remains active during the entire 40-min span that the observations lasted. Movies S1, S2, and S3 show these nests to be composed of many loops with more or less cospatial footpoints that light up and darken episodically. ...

The roughly fixed injected electromagnetic energy per particle leads to a wellorganized final solar wind speed. The physical principles behind the model have been well known for three decades: t ...
