In science:

Another condition to impede fallback concerns sufficient fast rotation.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
M ∝ t−5/3 ) it is possible that a magnetar field together with an rapid initial rotation may prevent the fallback accretion.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
For the ma jority of newborn NSs it is quite likely, that fallback accretion will appear, albeit not as heavy and field submerging as in case of SN 1987A.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
How deep the field will be submerged depends on the details of the supernova explosion as well as on the magnetic field strength and on the rotation rate of the NS when the fallback hits the surface.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
The submergence process in a NS whose field is that of ”standard” pulsars and for the fallback parameters of SN 1987A (for details see Geppert et al. 1999) is shown in Fig. 6.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
Distribution of the angle averaged magnetic field strength in the NS as a function of time for the fallback rate estimated for SN1987A.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
If temperature gradients in the crust are strong enough and maintained for a sufficient long period, a magnetic field may be rapidly generated and the NS becomes a pulsar in spite of heavy fallback accretion.
Turning Points in the Evolution of Isolated Neutron Stars' Magnetic Fields
Haberl: Planets or sub-stellar companions around neutron stars can give valuable insights into a neutron star’s formation history considering for example birth kicks or fallback disks.
On the Present and Future of Pulsar Astronomy
The emission mechanisms during a tidal disruption event (fallback, stream-stream collisions, compression, accretion) are complicated and not well understood.
UV/Optical Detections of Candidate Tidal Disruption Events by GALEX and CFHTLS
However, we can estimate the minimum mass accreted during the fallback phase of the debris by taking the lower limit to the peak luminosity, and integrating under the portion of the light curve well described by a t−5/3 power-law to get the total energy output.
UV/Optical Detections of Candidate Tidal Disruption Events by GALEX and CFHTLS
The blackbody temperatures, luminosities, and power-law decays of the flares are in excellent agreement with that expected from the simplest “fallback” models for the accretion of a tidally disrupted star.
UV/Optical Detections of Candidate Tidal Disruption Events by GALEX and CFHTLS
Their strong magnetic fields can inhibit accretion of light elements either from the supernova fallback or from the interstellar medium, leaving the surface heavy elements exposed.
Probes and Tests of Strong-Field Gravity with Observations in the Electromagnetic Spectrum
In this Letter, we investigate analytically the fate of the fallback matter, which may provide a luminous signal long after the disc is exhausted.
Delayed X-ray emission from fallback in compact-object mergers
Therefore, contrary to previous claims, our analysis suggests that fallback matter is not an efficient source of late time accretion power and is unlikely to cause the late flaring activity observed in SGRB afterglows.
Delayed X-ray emission from fallback in compact-object mergers
The fallback matter rather forms a radiation-driven wind or a bound atmosphere.
