We propose a novel mathematical method to construct an exact polytropic sphere in self-gravitating hydrostatic equilibrium, improving the non-linear Poisson equation. The central boundary condition for the present equation requires a ratio of gas pressure to total one at the centre, which is uniquely identified by the whole mass and molecular weight of the system. The special solution derived from the Lane-Emden equation can be reproduced. This scheme is now available for modelling the…

Approximate analytical solutions of the Lane–Emden equation for a self-gravitating isothermal gas sphere
The isothermal Lane-Emden equation arises in many astrophysical problems, in particular in modelling of a self-gravitating, polytropic gas in a spherically symmetric configuration. In this work, the
A theoretical model for electromagnetic characterization of a spherical dust molecular cloud equilibrium structure
Abstract A theoretical model is developed to study the equilibrium electromagnetic properties of a spherically symmetric dust molecular cloud (DMC) structure on the Jeans scales of space and time. It
A polytropic approach to semi-relativistic isothermal gas spheres at arbitrary temperature
We use the standard polynomial expansion technique to show the existence of a relation between the polytropic model and the description of gas spheres at finite temperature. A numerical analysis is
Polytropic atmospheres and the scaling of potential vorticity
SummaryPotential vorticity P is in widespread use as a diagnostic in atmospheric dynamics. Here, we employ the concepts of polytropic change of state and polytropic temperature for investigating the
Symmetry Reduction of Lane-Emden Equation for Polytropes
We describe an ansatz for symmetry reduction of the Lane-Emden equation for an arbitrary polytropic index n, admitting only one symmetry generator. For the reduced first order differential equation

We investigate the structure of self-gravitating polytropic stellar systems. We present a method that allows us to obtain approximate analytical solutions, ψn+(x) of the nonlinear Poisson equation
Self-similar collapse of isothermal spheres and star formation.
We consider the problem of the gravitational collapse of isothermal spheres by applying the similarity method to the gas-dynamic flow. We argue that a previous solution obtained by Larson and Penston
Polytropic gas spheres: an approximate analytic solution of the Lane-Emden equation
Polytropic models play a very important role in galactic dynamics and in the theory of stellar structure and evolution. However, in general, the solution of the Lane-Emden equation can not be given
Series solutions for polytropes and the isothermal sphere
The Lane–Emden equation for polytropic index and its limit of the isothermal sphere equation are singular at some negative value of the radius squared. This singularity prevents the real power series

We present similarity solutions that describe the runaway collapse of a rotating isothermal disk and its subsequent inside-out collapse. The similarity solutions contain the sound speed cs and the
Molecular cloud condensation as a tracer of low-mass star formation
STARS form inside dense clouds of molecular gas, but the details of the process, such as the quantity of gas that goes into stars and the rate at which the gas collapses, are still unknown. The
