Dear Ozah,

Please more explain about your question? And tell me which of my paper do you have question to discuss better. Your question is general.

Best,

Thank you Alireza Abdikian sir, for your quick response.

In general, dust ion-acoustic waves occur due to the compression and rarefaction of ion density in the presence of charged dust. In an astrophysical environment, there will be energetic particles. My question is that what are the extra possible features of waves that may be seen in the presence of energetic particles that do not happen in general plasma particles?

This question just arose in my mind.

Dear Ozah,

I am also interested in the specific features of waves due to the suprathermal particles. I have two previous related works that might be of interest to you.

The first paper studied the electron acoustic waves (EAWs) in kappa-distributed plasmas. It found that the weakly damped EAWs could propagate in non-thermal plasmas even if the electrons and ions have the same temperatures, which is unavailable in Maxwellian plasmas.

The second work investigated the drift instabilities in kappa-distributed plasmas. It found that the drift instabilities have an extra lower limit of wavenumber, which does not exist in equilibrium plasmas.

However, for the mentioned dust ion-acoustic waves, I am not sure whether some new properties exist in the presence of these suprathermal particles. It's a great research topic and I'd love to know if you find anything new.

Bests,

Prof. Ran Guo;

I have gone through your research articles. These articles will be very helpful to proceed with my work. Thanks for the recommendation. I will be in touch with you for any further queries.
