Effect of kappa-modified polarization force on Jeans instability in nonthermal EiBI-gravitating dust clouds
Dipankar Ray, Pralay Kumar Karmakar, Siddhartha Saikia
A semi-analytic model is developed to study the effects of kappa-distributed lighter constituents and the associated kappa-modified polarization force on the classical Jeans instab…

Pulsational mode stability in complex EiBI-gravitating polarized astroclouds with (r, q)-distributed electrons
Dipankar Ray, Pralay Kumar Karmakar
The pulsational mode of gravitational collapse (PMGC) originating from the combined gravito-electrostatic interaction in complex dust molecular clouds (DMCs) is a canonical mechani…
