The present article is the successor of Solar Dynamical Processes I. The previous article was focused on the Sun, its magnetic field with an emphasis on various dynamical processes occurring on the Sun, e.g. sunspots, prominence and bright points which in turn plays a fundamental role in regulating the space weather. This article is emphasized on the solar dynamical processes and develop an extensive understanding of the various phenomena involved in their origin. The article also covers various models and hypothesis put forward by pioneer scientists on the basis of their observation by space-borne and ground-based instruments. This article shade light over a wide range of dynamical processes e.g., solar flares, coronal mass ejections, solar jets and coronal holes. Solar jets, the small-scale transient activities are found to have association with the other transient activities (e.g., mini-flares and mini-filaments). Flares as well as the coronal mass ejections are responsible for releasing a large amount of high energy charged particles and magnetic flux into the interplanetary space, and are being considered as the main drivers of space weather.

“…Prominences are closely related to various solar dynamical processes such as flares, CMEs etc. Prominence eruption mostly leads to a CME which affect the interplanetary space very drastically and affect interplanetary space weather [87]. The particles and radiations emitted during the eruption can reach Earth and may lead to the various phenomenon on Earth.…”

The article gives a concise overview of solar dynamical processes and their impacts on the space weather. This article is based on the observational and theoretical developments made during last few decades. The article begins with a brief discussion of the Sun and the solar interior, from the core to the solar corona. We discuss the solar magnetic field and provide some basic understanding of the solar dynamo model. The solar dynamical processes, the transient as well as the gradual, are the manifestations of the Sun’s magnetic field. Magnetic reconnection, as well as submergence and emergence of magnetic flux tubes, plays an important role in the solar activities. This article tries to cover a range of dynamical processes, including sunspots, solar prominences and bright points. We also discussed various models of the dynamical processes along with their properties and effect on other activities occurring on the Sun.

“…[1][2][3] This ability of the phenolic donor oxygen atoms of such ligands, has been used to synthesize hetero binuclear complexes holding two metal ions in close proximity-one of transition metal and other alkali metal. 4,5 Schiff base transition metal complexes have a great medicinal values and industrial applications 6 , and metal ions play an important role in biological systems 7 . Greater permeability of metal complexes than metal ions further augments their importance.…”

Studies on Hetero Binuclear Complexes derived from Rubidium and Caesium salt of Acetyl salicylic acid (ASPIRIN) with N, N’-1,2-ethylenebis(5-nitrosalicylaldiminato) nickel(II)

Orient. J. Chem

Hetero binuclear complexes, [NiE5NSRbAp] and [NiE5NSCsAp], have been synthesized from Rubidium(I) and Caesium(I) salt of Acetyl salicylic acid (ASPIRIN) and N,N’-1,2-ethylenebis(5-nitrosalicylaldiminato) nickel(II) as ligand, respectively. This ligand [NiE5NS] has been prepared from Nickel(II) acetate and salen type dibasic Schiff base derived from 5-nitrosalicylaldehyde and Ethylenediamine. These novel hetero binuclear complexes obtained in pure solid state and their structures have been characterized with the help of Elemental analysis, Solubility, Magnetic property, Molar conductance measurement, FT-IR and Electronic absorption spectra. The results suggested molecular formula [NiLRbL’].3H2O and [NiL(H2O)2CsL’] with Square planar and Distorted Octahedral geometry about Ni2+, respectively for the two hetero binuclear complexes [NiE5NSRbAp] and [NiE5NSCsAp] where L = Deprotonated Schiff base ligand N,N’-1,2-ethylenebis(5-nitrosalicylaldiminato) nickel(II), L’ = Acetyl salicylate.
