MRI-triggered instability at the inner dead zone edge: disc evolution and burst modes tied to magnetic field strengths
Michael Cecil, Mario Flock, Daniel Steiner
The inner edge of the dead zone (DZIE) in protoplanetary discs is prone to episodic instability caused by the activation of the magneto-rotational instability (MRI) in the weakly t…
Planet formation at the inner edge of the dead zone -- I. the interplay between accretion outbursts and dust growth
Alexandros Ziampras, Tilman Birnstiel, Nicolas Kaufmann +2
The inner edge of the dead zone in protoplanetary disks has been shown to periodically go unstable, leading to accretion outbursts and annular substructure within the dead zone. Wh…
The role of detailed gas and dust opacities in shaping the evolution of the inner disc edge subject to episodic accretion
Michael Cecil, Mario Flock, Mykola G. Malygin +4
We investigate the effects of different dust and gas opacity descriptions on the structure and evolution of the inner regions of protoplanetary discs. The influence on the episodic…
Variability of the inner dead zone edge in 2D radiation hydrodynamic simulations
Michael Cecil, Mario Flock
The inner regions of protoplanetary disks are prone to thermal instability (TI), which can significantly impact the thermal and dynamic evolution of planet-forming regions. Observa…
