Nature of Quiet Sun Oscillations Using Data from the Hinode, TRACE, and SOHO Spacecraft
G. R. Gupta, S. Subramanian, D. Banerjee +2
We study the nature of quiet-Sun oscillations using multi-wavelength observations from TRACE, Hinode, and SOHO. The aim is to investigate the existence of propagating waves in the…
Spectroscopic Observations of Propagating Disturbances in a Polar Coronal Hole: Evidence of Slow Magneto-acoustic Waves
G. R. Gupta, L. Teriaca, E. Marsch +2
We focus on detecting and studying quasi-periodic propagating features that have been interpreted both in terms of slow magneto-acoustic waves and of high speed upflows. We analyze…
Propagating intensity disturbances in polar corona as seen from AIA/SDO
S. Krishna Prasad, D. Banerjee, G. R. Gupta
Polar corona is often explored to find the energy source for the acceleration of the fast solar wind. Earlier observations show omni-presence of quasi-periodic disturbances, travel…
Propagating waves in polar coronal holes as seen by SUMER and EIS
D. Banerjee, L. Teriaca, G. R. Gupta +3
To study the dynamics of coronal holes and the role of waves in the acceleration of the solar wind, spectral observations were performed over polar coronal hole regions with the SU…
On the statistical detection of propagating waves in polar coronal holes
G. R. Gupta, E. O'Shea, D. Banerjee +2
Waves are important for the heating of the solar corona and the acceleration of the solar wind. We have examined a long spectral time series of a northern coronal hole observed on…
