We present a local and linear analysis of the stability<br />in the presence of self-gravity and winds. The numerical results show the model with<br />self-gravity is unstable in all parts, while in a model without self-gravity, instability<br />can be observed only in regions near the central body. Eventually, the effect of wind<br />cooling on the model stability was discussed. According to the results, in systems<br />without self-gravity, wind cooling can help the system towards stability, but in the<br />presence of self-gravity, it is shown that our model will remain unstable in all regions.<br />Comparison of these result with observational evidence shows that this model can be<br />suitable for the explaining the behavior of the disks surrounding young stellar objects. https://ijaa.du.ac.ir/article_347_9c9bca287ba1cb00980109e5af54245f.pdf
