Grain Size segregation in debris discs
Philippe Thebault, Quentin Kral, Jean-Charles Augereau
In most debris discs, dust grain dynamics is strongly affected by stellar radiation pressure. As this mechanism is size-dependent, we expect dust grains to be spatially segregated…
LIDT-DD: A new self-consistent debris disc model including radiation pressure and coupling collisional and dynamical evolution
Quentin Kral, Philippe Thébault, Sébastien Charnoz
In most current debris disc models, the dynamical and the collisional evolutions are studied separately, with N-body and statistical codes, respectively, because of stringent compu…
An interferometric study of the Fomalhaut inner debris disk. III. Detailed models of the exozodiacal disk and its origin
J. Lebreton, R. van Lieshout, J. -C. Augereau +15
[Abridged] Debris disks are extrasolar analogs to the solar system planetesimal belts. The star Fomalhaut harbors a cold debris belt at 140 AU as well as evidence of a warm dust co…
