Self-Sustained Ionization and Vanishing Dead Zones in Protoplanetary Disks
We analyse the ionization state of the magnetohydrodynamically turbulent protoplanetary disks and propose a new mechanism of sustaining ionization. First, we show that in the quasi-steady state of turbulence driven by magnetorotational instability in a typical protoplanetary disk with dust grains the amount of energy dissipation should be sufficient for providing the ionization energy that is r...
متن کاملZombie Vortex Instability. I. a Purely Hydrodynamic Instability to Resurrect the Dead Zones of Protoplanetary Disks
There is considerable interest in hydrodynamic instabilities in dead zones of protoplanetary disks as a mechanism for driving angular momentum transport and as a source of particle-trapping vortices to mix chondrules and incubate planetesimal formation. We present simulations with a pseudo-spectral anelastic code and with the compressible code Athena, showing that stably stratified flows in a s...

متن کاملHow Dead are Dead Links ?
Research papers usually contain a significant number of links to other resources. For the most part, they reference other printed research papers, but there are also a non-trivial number of links to resources on the World Wide Web. Unlike printed research papers, references to WWW resources may become invalid after time. The server containing the page may be taken offline, be temporarily unavai...
متن کاملClimate change and dead zones.
Estuaries and coastal seas provide valuable ecosystem services but are particularly vulnerable to the co-occurring threats of climate change and oxygen-depleted dead zones. We analyzed the severity of climate change predicted for existing dead zones, and found that 94% of dead zones are in regions that will experience at least a 2 °C temperature increase by the end of the century. We then revie...
