EFFECTS OF WIND VELOCITY DRIVEN BY ALFVEN WAVES ON THE LINE PROFILES FOR 32 CYG

Alfven파에 의한 항성풍 속도가 32 Cyg의 선윤곽에 미치는 효과

We calculate the theoretical line profiles for 32 Cyg in order to investigate the influence of various velocity fields. Line profiles are calculated with wind accelerations driven by Alfven waves and described by velocity parameters. The results for Alfvenic wave model show weakened line profiles. For the orbital phases ${\Phi}$=0.78 and ${\Phi}$=0.06 the Alfvenic models show strong absorption part due to very low densities at the surface of the supergiant. Hence, we conclude the velocity gradient of the wind near the supergiant could influence on the theoretical line formation.
