This study has been made using IUE high resolution spectra which shows many singly ionised dominant species like Si II, Fe II and others, also highly ionised species like Al III and CIV have been seen in the spectra. Estimated radial velocity of these line, have been identified with the swept up region around the HD148937. From the study we have derived the age of the bubble to be 1.31x10^5 years, which is less than the age of the central star (3-4 Myr). |
