Impact of MHD disk wind on early evolutionary stage of protoplanetary disk and dust growth

We perform one-dimensional protoplanetary disk evolution calculations to investigate the impact of the magnetohydrodynamic (MHD) disk wind on disk evolution and dust particle growth.To examine the effect of the MHD disk wind, we compare calculations with and without it. In disk evolution calculations, episodic accretion events (or outbursts) occur repeatedly, as reported in previous studies, regardless of the presence of the MHD disk wind. However, the time interval between outbursts is shorter in cases with the MHD disk wind than in those without it. For dust particle growth, during the infall phase, there is no significant difference between cases with and without the MHD disk wind, and dust particles grow to approximately 1-10\,cm. Inside the $\mathrm{H_{2}O}$ snowline, the maximum dust particle size is limited by the collisional fragmentation of dust particles. Outside the snowline, the maximum dust particle size is primarily determined by radial drift. After the infall phase, when the MHD disk wind is considered, the disk temperature decreases noticeably, and the snowline migrates inward. As a result, the dust particles can grow beyond 10\,cm. Therefore, we find that the MHD disk wind plays a crucial role in dust growth and planet formation after the infall phase.
