Description
This study investigates the large scale structure and time evolution of stellar
astrospheres with magnetohydrodynamic (MHD) simulations. We study the
heliosphere as an first example of an astrosphere, and then investigate Lambda
Cephei, a massive runaway O-type star. Astrospheres are formed when stellar
winds meet the interstellar medium (ISM). This produces a variety of phenomena
including the termination shock (TS), astropause (AP), and bow shock
(BS). This project examines the model results of how the heliosphere evolves
and stabilizes as it expands from 50 000 to 700 000 years. According to the
simulations, the TS as well as BS steadily move outward with time, while the
astrosphere possesses a bullet-shaped asymmetric form.
