The evolution of our understanding of coronal mass ejections
Vourlidas, Angelos; Stenborg, Guillermo; Howard, Russell A.
The unexpected observation of a sudden expulsion of mass through the solar corona in 1971 opened up a new field of interest in solar and stellar physics. The discovery came from a white-light coronagraph, which creates an artificial eclipse of the Sun, enabling the viewing of the faint glow from the corona. This observation was followed by many mo…
Exploring the impact of imaging cadence on inferring CME kinematics
Pant, Vaibhav; Banerjee, Dipankar; Patel, Ritesh +2 more
The kinematics of coronal mass ejections (CMEs) are crucial for understanding their initiation mechanism and predicting their impact on Earth and other planets. With most of the acceleration and deceleration occurring below 4 R⊙, capturing this phase is vital to better understand their initiation mechanism. Furthermore, the kinematics of CMEs in t…
SITCoM: SiRGraF Integrated Tool for Coronal dynaMics
Patel, Ritesh; Udhwani, Purvi; Shrivastav, Arpit Kumar
SiRGraF Integrated Tool for Coronal dynaMics (SITCoM) is based on the Simple Radial Gradient Filter used to filter the radial gradient in the white-light coronagraph images and bring out dynamic structures. SITCoM has been developed in Python and integrated with SunPy and can be installed by users with the command pip install sitcom. This enables …
