Quasi-periodic Fast-mode Magnetosonic Wave Trains Within Coronal Waveguides Associated with Flares and CMEs
Wei Liu, Leon Ofman, Brittany Broder +2
Quasi-periodic, fast-mode, propagating wave trains (QFPs) are a new observational phenomenon recently discovered in the solar corona by the Solar Dynamics Observatory with extreme…
Evidence of thermal conduction suppression in hot coronal loops: Supplementary results
Tongjiang Wang, Leon Ofman, Xudong Sun +2
Slow magnetoacoustic waves were first detected in hot (6 MK) flare loops by the SOHO/SUMER spectrometer as Doppler shift oscillations in Fe XIX and Fe XXI lines. Recently, such…
Stability of rotating magnetized jets in the solar atmosphere. I. Kelvin-Helmholtz instability
T. V. Zaqarashvili, I. Zhelyazkov, L. Ofman
Observations show various jets in the solar atmosphere with significant rotational motions, which may undergo instabilities leading to heat ambient plasma. We study the Kelvin-Helm…
Nonlinear MHD waves in a Prominence Foot
Leon Ofman, Kalman Knizhnik, Therese Kucera +1
We study nonlinear waves in a prominence foot using 2.5D MHD model motivated by recent high-resolution observations with Hinode/SOT in Ca~II emission of a prominence on October 10,…
Evidence of thermal conduction suppression in a solar flaring loop by coronal seismology of slow-mode waves
Tongjiang Wang, Leon Ofman, Xudong Sun +2
Analysis of a longitudinal wave event observed by the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) is presented. A time sequence of 131 A images…
Three dimensional MHD Modeling of Vertical Kink Oscillations in an Active Region Plasma Curtain
Leon Ofman, Marzia Parisi, Abhishek K. Srivastava
Observations on 2011 August 9 of an X6.9-class flare in active region (AR) 11263 by the Atmospheric Imaging Assembly (AIA) on-board the Solar Dynamics Observatory (SDO), were follo…
Spectroscopic Diagnosis of Propagating disturbances in coronal loops: Waves or flows?
Tongjiang Wang, Leon Ofman, Joseph M. Davila
The analysis of multiwavelength properties of propagating disturbances (PDs) using Hinode/EIS observations is presented. Quasi-periodic PDs were mostly interpreted as slow magnetoa…
