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, ...
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 ...
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 ...
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 ...
