“…To clarify the situation, the last equation implies that this compact star results from the equilibrium between these three different forces, as is mentioned in Ref. [50]. In particular, if F p = 0, we obtain the standard TOV equation.…”

Within the framework of Einstein’s General Relativity we study strange quark stars assuming an interacting equation-of-state. Taking into account the presence of anisotropies in a sphere made of ultra dense matter, we employ the formalism based on the complexity factor. We integrate the structure equations numerically imposing the appropriate conditions both at the center and at the surface of the stars, thus obtaining interior solutions describing hydrostatic equilibrium. Making use of well-established criteria, we demonstrate that the solutions obtained here are well behaved and realistic. A comparison with another, more conventional approach, is made as well. Our numerical results are summarized in a number of figures.

“…The equilibrium for a compact star is maintained by the balance of three forces, as established by the previous equation ( 8) [61]. It is noteworthy that if F p is equal to zero, then the standard TOV equation is obtained.…”

We investigate exotic stars composed of dark energy within the context of Einstein's General Relativity, by applying an extended Chaplygin gas equation-of-state. To account for anisotropies, we utilize a formalism based on the complexity factor to obtain numerical solutions. By applying well-established criteria, we demonstrate that the solutions are physically valid and well-behaved. In addition, a comparison with a more conventional approach is also conducted.

“…Anisotropic compact stellar objects admitting a linear EOS was studied by [12]. [13] presented a class of relativistic solutions to Einstein field equations for an anisotropic matter distribution utilizing the Buchdahl ansatz for the metric function g rr . Recently, [14] investigated a charged anisotropic stellar solution in paraboloidal spacetime using a linear EOS.…”

Investigation on the diversity of Odonates revealed a total of 38 species belonging to two suborders, six families, and 24 genera in and around Vadodara, in Gujarat, which included 15 species of Zygoptera (damselfly) and 23 species of Anisoptera (dragonfly). Out of the 38 species, 10 species are new records for the Vadodara. Most number of species was found in water reservoirs as compared to urban ponds and area around Mahi River. Furthermore, it was observed that areas around the rivers were adversely affected because of nearby sand mining. Amongst damselflies and dragonflies the population of damselflies was richer. Renovation of Urban ponds leads to decrease in their diversity due to loss of vegetation indicating anthropogenic pressure on species diversity.
