My View of 1999 TRACE Workshp |
- Coronal Heating Mechanisms
- Nanoflares (DC) or MHD Waves (AC)?
- Nanoflares Study
- Energy distribution (Parnell and Jupp; Aschwanden et al. )
- Energy cutoff (Aschwanden)
- Are nanoflares not enough for coronal heating?
- MHD Waves Study
- Observation of standing kink waves (loop oscillation, Aswanden et al.)
- Oscillation damping and inferred disspation coefficients (DeLuca et al.)
- EUV loop brightenings: MHD Compression waves? (Nightingale et al.)
- Large-scale propagating disturbance (Wills-Davey and Thompson)
- Are MHD waves generated by reconnection events in the
chromosphere and transition region?
- Jets and Flows
- helical structures and spinning motions in EUV jets (Shimojo et al. )
- counter-streaming in H alpha loops (Qiu et al. )
- reconnection is a possible source of twists and spinning motions
(Chae)
- Do jets and loop flows have a common origin?
- Flux Cancellation
- Flux cancellation is inpreted to be a result of (Sweet-Parker type)
reconnection.
- Theories predict the temperature minimum region for a height
of reconnection ( Chae 1998, Litvinenko 1999,
Sturrock 1999)
- K. Harvery observed chromospheric flux cancellation preceding
photospheric one
- Flux cancellation is found to be associated with filament flows
(Litvinenko and Martin )
- What is the height of reconnection in charge of flux cancellation?
- Prospects
- Important to study small-scale activities related with magnetic reconnection
in the lower atmosphere like
- flux cancellation
- jets
- flows
- MHD waves
- Further Studies of Flux Cancellation
- high spatio-temporal resolution observations (0.2", 30 s)
- Spectrograph-based observations
- high temporal observations jointed by TRACE
- Systematic investigation of disturbances produced by microflares
- jets
- flows (filament flows or loop flows)
- waves: time-distance analysis?
