High resolution spectroscopy of the hot post-AGB stars : IRAS13266-5551 (CPD-55 5588) and IRAS17311-4924 (Hen3-1428)
G. Sarkar Nee Gauba, M. Parthasarathy, Bacham E. Reddy
The high resolution spectra covering the wavelength range 4900 A to 8250 A of the hot post-AGB stars IRAS13266-5551 (CPD-55 5588) and IRAS17311-4924 (Hen3-1428) reveal absorption l…
UV(IUE) spectra of hot post-AGB candidates
G. Sarkar Nee Gauba, M. Parthasarathy
Analysis of the low resolution UV(IUE) spectra of 15 hot post-AGB candidates is presented. The UV(IUE) spectra of 10 stars suggest partial obscuration of the hot stars due to circu…
Circumstellar dust shells of hot post-AGB stars
G. Sarkar Nee Gauba, M. Parthasarathy
Using a radiative transfer code (DUSTY) parameters of the circumstellar dust shells of 15 hot post-AGB stars have been derived. Combining the optical, near and far-infrared (ISO, I…
