Coronal hole boundaries at small scales: IV. SOT view Magnetic field properties of small-scale transient brightenings in coronal holes
Z. Huang, M. S. Madjarska, J. G. Doyle +1
We study the magnetic properties of small-scale transients in coronal hole. We found all brightening events are associated with bipolar regions and caused by magnetic flux emergenc…
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…
Solar fine-scale structures. I. Spicules and other small-scale, jet-like events at the chromospheric level: observations and physical parameters
G. Tsiropoula, K. Tziotziou, I. Kontogiannis +3
Over the last two decades the uninterrupted, high-resolution observations of the Sun, from the excellent range of telescopes aboard many spacecraft complemented with observations f…
Coronal hole boundaries at small scales: III. EIS and SUMER views
M. S. Madjarska, Z. Huang, J. G. Doyle +1
We report on the plasma properties of small-scale transient events identified in the quiet Sun, coronal holes and their boundaries. We use spectroscopic co-observations from SUMER/…
The Diagnostic Potential of Transition Region Lines under-going Transient Ionization in Dynamic Events
J. G. Doyle, A. Giunta, A. Singh +4
We discuss the diagnostic potential of high cadence ultraviolet spectral data when transient ionization is considered. For this we use high cadence UV spectra taken during the impu…
Off-limb (spicule) DEM distribution from SoHO/SUMER observations
K. Vanninathan, M. S. Madjarska, E. Scullion +1
In the present work we derive a Differential Emission Measure (DEM) dis- tribution from a region dominated by spicules. We use spectral data from the Solar Ultraviolet Measurements…
