Ion Acoustic Solitons in a Relativistic Warm Plasma with Density Gradient
نویسنده
چکیده
Modified Korteweg-deVries equation (mK-dV), which governs the behavior of ion acoustic solitons in a relativistic warm plasma with density gradient, is derived. The electron inertia is also taken into account which is important when the streaming ions are present in the plasma. A solution of the mK-dV equation is obtained for the constant density gradient When the ion acoustic soliton propagates into the lower plasma density region, its amplitude and energy increase, but the width decreases,* the same is the case for the stronger density gradients.

Investigation of ion acoustic solitons in three component plasma including positive and negative ions and Maxwellian electrons shows that negative to positive relative ion density plays a critical role so that by changing ν over the range of 0<ν<1 compressive or rarefactive solitons will propagate. In this paper, it is shown that due to the superthermal electrons, there are three domains for ...
