A study of a coronal hole associated with a large filament eruption
We report the results of a detailed study of an equatorial coronal hole and a dimming region related to the eruptions of a nearby large filament and subsequent coronal mass ejections (CMEs). The dynamic eruptions of the ...
Diﬀerent stages of evolution of prominence and the associated CMEs
We study the diﬀerent evolutional stages of a large quiescent prominence, mainly considering its dynamic/thermal instabilities occurred close from the boundary of coronal hole (CH). We identify the critical conditions, ...
Short term topological changes of coronal holes associated with prominence eruptions and subsequent CMEs
We study the short-term topological changes of equatorial and polar coronal hole (CH) boundaries, such as a variation of their area and disintegration, associated to reconnection with nearby (within 15° distance) quiescent ...
Evolution of a group of coronal holes associated with eruption of nearby prominences and CMEs
We present the results of detailed study of a set of activities developed on one of three enclosed sectors of solar region during the period of February 07-13, 2012. We found the sequence of certain topological perturbations ...
