... The concept of continuous solar wind developed in 1950's. First, Biermann (1951, 1957) observed comet tails as they passed close to the Sun , and explained the observed tail deflection by a continuous flux of protons from the Sun. Then Parker (1959) showed that the solar corona must expand, and called the outward streaming coronal gas 'solar wind'. ... The expanding solar wind drags also the solar magnetic field outward, forming what is called the interplanetary magnetic field (IMF) . ...

... A theory suggests that a certain sub-class of gamma-ray bursts all have the same absolute magnitude. ... The author claims that this absolute magnitude is so different from that in the previous sample that this must belong to a new sub-class of gamma-ray bursts. ... To do this, there needs to be some feature in their spectra which correlates with their absolute magnitude. ... Consider a telescope which is continually monitoring a star, looking for transits due to planets orbiting this star. ...
