Energetics of Hi-C EUV Brightenings
Srividya Subramanian, Vinay L. Kashyap, Durgesh Tripathi +2
We study the thermal structure and energetics of the point-like EUV brightenings within a system of fan loops observed in the active region \textsl{AR~11520}. These brightenings we…
The Evolution of the EM Distribution in the Core of an Active Region
Giulio Del Zanna, Durgesh Tripathi, Helen Mason +2
We study the spatial distribution and evolution of the slope of the Emission Measure between 1 and 3~MK in the core active region NOAA~11193, first when it appeared near the centra…
Emission Measure Distribution for Diffuse Regions in Solar Active Regions
Srividya Subramanian, Durgesh Tripathi, James A. Klimchuk +1
Our knowledge of the diffuse emission that encompasses active regions is very limited. In the present paper we investigate two off-limb active regions, namely AR10939 and AR10961,…
Initiation of CME event observed on November 3, 2010: Multi-wavelength Perspective
Sargam Mulay, Srividya Subramanian, Durgesh Tripathi +2
One of the major unsolved problems in Solar Physics is that of CME initiation. In this paper, we have studied the initiation of a flare associated CME which occurred on 2010 Novemb…
Interacting CMEs and their associated flare and SEP activities
A. Shanmugaraju, S. Prasanna Subramanian
We have analyzed a set of 25 interacting events which are associated with the DH type II bursts. These events are selected from the Coronal Mass Ejections observed during the perio…
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…
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/…
Coronal hole boundaries evolution at small scales: II. XRT view Can small-scale outflows at CHBs be a source of the slow solar wind?
S. Subramanian, M. S. Madjarska, J. G. Doyle
We developed an automated procedure for the identification of transient brightenings in images from the X-ray telescope on-board Hinode taken with an Al Poly filter in the equatori…
