Fast methods for tracking grain coagulation and ionization. I. Analytic derivation
Pierre Marchand, Vincent Guillet, Ugo Lebreuilly +1
Dust grains play a major role in many astrophysical contexts. They affect the chemical, magnetic, dynamical, and optical properties of their environment, from galaxies down to the…
A statistical analysis of dust polarization properties in ALMA observations of Class 0 protostellar cores
V. J. M. Le Gouellec, A. J. Maury, V. Guillet +8
Recent observational progress has challenged the dust grain-alignment theories used to explain the polarized dust emission routinely observed in star-forming cores. In an effort to…
Dust coagulation feedback on magnetohydrodynamic resistivities in protostellar collapse
V. Guillet, P. Hennebelle, G. Pineau des Forêts +3
The degree of coupling between the gas and the magnetic field during the collapse of a core and the subsequent formation of a disk depends on the assumed dust size distribution. We…
A systematic study of radiative torque grain alignment in the diffuse interstellar medium
Stefan Reissl, Vincent Guillet, Robert Brauer +3
Context. Planck observations demonstrated that the grain alignment efficiency is almost constant in the diffuse ISM. Aims. We test if the Radiative Torque (RAT) theory is compatibl…
Polarized emission by aligned grains in the Mie regime : application to protoplanetary disks observed by ALMA
V. Guillet, J. M. Girart, A. J. Maury +1
The azimuthal polarization patterns observed in some protoplanetary disks by ALMA at millimeter wavelength have raised doubts about their being produced by dust grains aligned with…
Indirect evidence of significant grain growth in young protostellar envelopes from polarized dust emission
Valeska Valdivia, Anaelle Maury, Robert Brauer +4
How and when in the star formation sequence do dust grains start to grow into pebbles is a cornerstone question to both star and planet formation. We compute the polarized radiativ…
