- Description:
- In a previous study of the A-type supergiants observed with IUK we divided these stars in two groups, the most luminous ones, which showed clear evidence of stellar wind and mass loss in their line profiles and the less luminous ones which did not show these characteristics. New observations of some A supergiants confirm the difference between those two groups. Moreover the less luminous (Ib) A-type supergiants do show weak signs of wind and mass loss compared with the most luminous A supergiants and their variation is more spectacular.
