Tether-Cutting Energetics of a Solar Quiet-Region Prominence Eruption

This study examines the energetics of a quiet-region prominence eruption and investigates the mechanism driving such eruptions. Observational data and simulations are used to estimate the energy required and the heating associated with tether-cutting reconnection. The results suggest that quiet-region and active-region eruptions are different manifestations of the same magnetic eruption process.

  1. 太陽雑誌会 2004/2/2 殿岡 TETHER-CUTTING ENERGETICS OF A SOLAR QUIET-REGION PROMINENCE ERUPTIONAlphonse C. Sterling1, 2 and Ronald L. MooreNASA Marshall Space Flight Center, SD50/Space Science Department, Huntsville,AL 35812;asterling@solar.stanford.edu, ron.moore@nasa.govReceived 2003 May 31; accepted 2003 August 19 The Astrophysical Journal, 599:1418–1425, 2003 December 20

  2. Two different types of filament and prominence eruptions .. active region and quiet region eruptions “both types of eruptions are aspects of a more general magnetic eruption process and that the mechanism driving these eruptions is the same in the two cases” Quiet-region prominence eruption of 1999 Feb 8-9 the expected observational detectability of tether-cutting reconnection Introduction

  3. Instrumentation and data

  4. Observations: EIT 284A

  5. Observations: SXT

  6. Observations: Figure3

  7. Light curves and trajectory of the prominence. Upper: EIT, Lower: SXT Observations:Figure4

  8. estimating the amount of energy required for the prominence eruption, Energetics the gravitational energy dominates the kinetic energy by 2 orders of magnitude.

  9. Estimating heating energy associated with tether cutting reconnection. (radiated energy) + (thermal energy) Energetics -2- a heating rate of 105–107 ergs cm2 s1,

  10. Previous results.. quiet region and active region eruptions Dimmings The heating due to tether cutting reconnection Summaries regardign tether cutting reconnection The assumption of a constant energy ratio Discussion
