Stellar comet spear

One of the consequences of the evolutionary process of the planetary system is the appearance of comets, asteroids, and even planets (ACP) unbound to their parent star. These small bodies are scattered into interstellar space, orbit the Galactic Center and expand along the star orbit with time. The formed structure resembles a spear in its shape. Similar ACP spears have all stars with planetary systems in the Galaxy. Since such stars are part of the open clusters population, they scatter and form the ACPS spears. In this paper, we performed numerical modeling of the ACP and ASPC spears and estimated their parameters, such as length, width, and time of formation.
