... There is one section not shown in Figure 1.2 that lies between the termination shock and the heliosphere: the heliosheath. In this region, the solar wind becomes turbulent and continues to slow. The next section of the heliosphere is the heliopause. This is the precise boundary where the winds of th ...

It was later discovered that all of the gas planets had ring systems, albeit faint, of their own. Saturn is a ...

Dawes Review. The tidal downsizing hypothesis of planet formation

Kuiper’s top-down scenario of planet formation is therefore made plausible by planet migration; it was recently re-invented (Boley et al., 2010) and re-branded ”Tidal Downsizing” hypothesis (Nayakshin, 2010a). This review presents the main ideas behind the Tidal Downsizing scenario, recent theoretic ...
