Constraints on mechanisms of chondrule formation from chondrule precursors and chronology of transient heating events in the protoplanetary disk
chondrules refractory inclusions chondrule precursors transient heating
2017/4/10
The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type
in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...

Shear heating not a cause of inverted metamorphism
Shear heating not a cause inverted metamorphism
2014/4/15
An archetypal example of inverted metamorphism purportedly resulting from shear heating is found in the Pelona Schist of southern California (United States). Recent studies demonstrate that the Pelona...
Magnetosphere-Ionosphere Coupling Through E-region Turbulence: Anomalous Conductivities and Frictional Heating
Anomalous Conductivities Frictional Heating
2017/3/22
Global magnetospheric MHD codes using ionospheric conductances based on laminar
models systematically overestimate the cross-polar cap potential during storm time by
up to a factor of two. At these ...
Three‐dimensional earthquake sequence simulations with evolving temperature and pore pressure due to shear heating: Effect of heterogeneous hydraulic diffusivity
Three‐dimensional earthquake sequence simulations evolving temperature pore pressure due to shear heating:heterogeneous hydraulic diffusivity
2014/4/8
A new methodology for three‐dimensional (3‐D) simulations of earthquake sequences is presented that accounts not only for inertial effects during seismic events but also for shear‐induced temperature ...
Viscous heating in fluids with temperature-dependent viscosity:implications for magma flows
Viscous heating in fluids temperature-dependent viscosity magma flows
2009/11/12
Viscous heating plays an important role in the dynamics of fluids with strongly temperature-dependent viscosity because of the coupling between the energy and momentum equations. The heat generated by...

This paper concisely summarizes and critically reviews recent work by the authors on models of the heating of the solar corona by resonance of ions with high-frequency waves (up to the proton cyclotro...
MHD turbulence and heating of the open field-line solar corona
MHD turbulence open field-line solar corona
2009/11/11
This paper discusses the possibility that heating of the solar corona in open field-line regions emanating from coronal holes is due to a nonlinear cascade, driven by low-frequency or quasi-static mag...
Magnetic field turbulence,electron heating,magnetic holes,proton cyclotron waves,and the onsets of bipolar pulse (electron hole) events:a possible unifying scenario
Magnetic field turbulence electron heating magnetic holes proton cyclotron waves
2009/11/11
Two electron heating events have been identified on 20 May 1996 when Polar was in the polar cap/polar cusp boundary layer. The electron heating events were located within magnetic holes/cavities/bubbl...
Intermittent heating of the solar corona by MHD turbulence
Intermittent heating solar corona MHD turbulence
2009/11/3
As the dissipation mechanisms considered for the heating of the solar corona would be sufficiently efficient only in the presence of small scales, turbulence is thought to be a key player in the coron...
Coronal heating and wind acceleration by nonlinear Alfvén waves–global simulations with gravity,radiation,and conduction
Coronal heating wind acceleration nonlinear Alfvén waves global simulations
2009/10/30
We review our recent results of global one-dimensional (1-D) MHD simulations for the acceleration of solar and stellar winds. We impose transverse photospheric motions corresponding to the granulation...
