	<span lang=\"EN-US\">The introduction of an exponential or power law gradient
in the interstellar medium (ISM) allows to produce an asym</span><span lang=\"EN-US\">metric
evolution of the supernova remnant (SNR) when the framework of the thin layer
approximation is adopted. Un</span><span lang=\"EN-US\">fortunately both the exponential and power law
gradients for the ISM do not have a well defined physical meaning. The physics
conversely is well represented by an isothermal self-gravitating disk of
particles whose velocity is everywhere Maxwellian. We derived a law of motion
in the framework of the thin layer approximation with a control parameter of
the swept mass. The photon¡¯s losses,</span><span lang=\"EN-US\"> which</span><span lang=\"EN-US\"> are often neglected in the thin layer
approximation, are modeled trough velocity dependence. The developed framework
is applied to SNR 1987A and the three observed rings are simulated.</span>
