I will present a new post-processing pipeline for (magneto-)hydrodynamic simulations of protoplanetary accretion disks and results from its first application. By combining publicly available radiative transfer and astrochemistry tools, we process snapshots from radiative, non-ideal MHD simulations of thermally-assisted centrifugal outflows from disks (Gressel et al. 2020) to search for...
Consistent time-dependent modeling of microphysics, especially thermochemistry and radiation-matter interactions, is desired by the studies on protoplanetary disks. In this talk, I will introduce our GPU-accelerated numerical infrastructures for consistent microphysics co-evolved with (magneto-)hydrodynamic simulations. Their applications in the studies of protoplanetary disk dispersal...
From molecular clouds to protoplanetary disks, non-ideal magnetic effects are important in many astrophysical environments. Indeed, in star and disk formation processes, it has become clear that these effects are critical to the evolution of the system. The efficacy of non-ideal effects are, however, determined by the complex interplay between magnetic fields, ionising radiation, cosmic rays,...
Winds from planet forming discs can be photoevaporative or magnetically driven. Both types of wind can remove mass from the disc and affect the surface density evolution of the planet making material. A basic difference between these two types of wind is that magnetic winds, unlike photoevaporative winds can also remove angular momentum and thus drive accretion in the system. Indeed a...
I will discuss a few applications requiring coupling chemistry with gas dynamics in protoplanetary disks. The most common application is to obtain the level of ionization, which determines the coupling between gas and magnetic fields. In the bulk disk, as far as ionization is concerned, equilibrium chemistry holds unless sub-micron sized grains are depleted. This allows magnetic diffusivities...
The influence of magnetic fields in protoplanetary disk evolution depends sensitively on the level of ionisation present. Protoplanetary disks are thought to be only very weakly ionised which provides imperfect coupling to magnetic fields and influences disk dynamics. Understanding the sources of ionisation, such as cosmic rays, present in the disks underpins our overall understanding of how...
