Observations of Mini Coronal Dimmings Caused by Small-scale Eruptions in the Quiet Sun

چکیده

Abstract Small-scale eruptions could play an important role in coronal heating, generation of solar energetic particles (SEPs), and mass source the wind. However, they are poorly observed, their characteristics, distributions, origins remain unclear. Here a mini dimming was captured by recently launched Solar Orbiter spacecraft. The observations indicate that minifilament eruption results takes away approximately (1.65 ± 0.54) × 10 13 g mass, which also exhibits similar features as sources SEP events. released magnetic free energy is order ∼10 27 erg. Our suggest weak constraining force makes flux rope associated with easily enter torus-unstable domain. We discuss constraints from low-altitude background fields may be general condition for quiet-Sun eruptions, provide possible mechanism transport material lower to middle or even higher corona.

دسته‌بندی تاریکی‌های کوچک‌مقیاس از فوران‌های تابش‌های فرابنفش دور خورشید با استفاده از نظریه گراف

Coronal dimmings in both micro and macro scales, can be observed by extreme ultraviolet images, recorded from Solar Dynamics Observatory or Atmospheric Imaging Assembly (SDO/AIA). Mini-dimmings are sometimes associated with wave-like brightening, called coronal mass ejections. Here, the sun full disk images with 171 Å wavelenght, cadence of 2.5, and  0.6 arcsec cell size, were taken on 3 March ...

Turbulent magnetic fields in the quiet Sun: implications of Hinode observations and small-scale dynamo simulations

Using turbulent MHD simulations (magnetic Reynolds numbers up to≈ 8000) and Hinode observations, we study effects of turbulence on measuring the solar magnetic field outside active regions. Firstly, from synthetic Stokes V profiles for the FeI lines at 6301 and 6302 Å, we show that a peaked probability distribution function (PDF) for observationally-derived field estimates is consistent with a ...

Small-scale Magnetic Reconnection in the Quiet Sun

Recent observations indicate that small-scale magnetic re-connection ubiquitously occurs in the quiet Sun as well as in active regions. Particularly interesting is the latest nding of close associations among (1) magnetic ux cancellation seen from photospheric magne-tograms, (2) chromospheric uppow events seen in the H line and (3) transition region explosive events seen in UV lines. I present ...

Quiet Sun coronal heating: statistical model

Recent observations of Krucker & Benz (1998) give strong support to Parker’s hypothesis (1988) that small scale dissipative events make the main contribution to quiet Sun coronal heating. They also showed that these small scale events are associated not only with the magnetic network, but also with the cell interiors (Benz & Krucker, 1998). Taking into account in addition the results of the ana...

Solar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence

Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special day, both of coronal mass ejection and prominence were observed. The average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
