Signatures of red-shifted foot points in the quiescent coronal loop system
Original language description
We observed quiescent coronal loops using multi-wavelength observations from the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) on 13 April 2016. The flows at the foot points of such loop systems are studied using spectral data from the Interface Region Imaging Spectrograph (IRIS). The Doppler velocity distributions at the foot points lying in the moss region show the negligible or small flows at the Ni I, MgII k3, and C II line corresponding to upper photospheric and chromo-spheric emissions. Significant red shifts (downflows) ranging from 1 to 7 kms(-1) are observed at Si IV (1393.78 angstrom; log(T=K/D 4.8), which is found to be consistent with the existing results regarding dynamical loop systems and moss regions. Such downflows agree well with the impulsive heating mechanism reported earlier.
