Abstract


Background/Objective: Planetary nebulas are glowing shell of gases that are ejected from the central star. The main objective of this paper is to present a model for NGC6369 planetary nebula. Methods: The central star is an old star (type O) with magnitudes between -3 and +5. These stars are quickly evolving into white dwarfs. In this paper, dynamic and ionized structure of NGC 6369 planetary nebula based on the interaction model of two stellar winds is discussed. Results: This high velocity wind will collide with a super stellar wind after a while, and creates a dense area, where this area is the same nebula under study. The stellar wind begins to blow at a mass loss rate of 1 x 10 -5 Msun/yr and a speed of 10 km/ s. After a while, the wind ends, and a high velocity wind starts blowing. Conclusion: If the problem assigned a typical velocity of 2000 km/ s, it has achieved a mass loss rate of 4.5 x 10 -9 Msun/yr.
