The westerly dipping reflections show that the dune has migrated from east to west and is accreting on its western side. |

Only the upper 4 km of this sequence is accreting at the current subduction zone. |
|
As planetesimals grow still larger, their gravitational attraction increases, allowing them to become even more effective at accreting nearby planetesimals. |
|
It is adapted to habitat made up of shifting, accreting sand layers, as well as that composed of stabilised dunes. |
|
These millisecond pulsars have been spun up and rejuvenated by accreting matter from a companion star. |
|
When the accreting object is a neutron star or a black hole, the gas in the inner accretion disc orbits at very high speeds because of its proximity to the compact object. |
