| Instead, accreting matter falls directly on the magnetic poles of the white dwarf. |
| 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. |
| As planetesimals grow still larger, their gravitational attraction increases, allowing them to become even more effective at accreting nearby planetesimals. |
| Only the upper 4 km of this sequence is accreting at the current subduction zone. |
| To hunt for accreting white dwarfs, astronomers looked for X-rays of a particular energy, produced when gas hitting the star's surface undergoes nuclear fusion. |
| The westerly dipping reflections show that the dune has migrated from east to west and is accreting on its western side. |
