Because a «small» protoplanet (up to a few Earth masses) lacks sufficient gravitational pull to open a gap in the protostar's disk, it will move inward as the disk lying inside the protoplanet's orbit transfers angular momentum to it at a slower rate than it is transferring angular momentum to the outer disk (through interactions with Lindblad resonances induced in the disk).

The pulsar gains angular momentum from the infalling gas and ramps up its spin rate as more gas falls onto it.

The SOI also maps to the estimate of the global averaged angular momentum, also known as wind energy.

So we're back to exchanging angular momentum between the lithosphere (crust + solid mantle) and the core, mediated somehow by the asthenosphere, the same picture as in Dickey et al 2011 and its many predecessors: «Previous investigators have found that the LOD fluctuations are largely attributed to core - mantle interactions.»

As other posters have indicated with the point about how ice lost from ice - caps changes the angular momentum, the movement of water and atmosphere over the surface has an impact on the angular momentum and therefore a major ENSO event will show up in a LOD fluctuation.
