A multiwavelength study of LS II+34(0)26: a hot post-AGB star in the process of becoming a planetary nebula

Autor: GarciaLario, P, Parthasarathy, M, deMartino, D, deCordoba, LSF, Monier, R, Manchado, A, Pottasch, [No Value]

Publikováno v: Astronomy & astrophysics, 326(3), 1103-1110. EDP Sciences

We present the results from a multiwavelength analysis of LS II+34(0)26, recently identified as a low mass post-AGB star and not a massive population I B-type star, as previously thought. We confirm that the central star is a carbon-poor post-AGB sta

IRAS-17423-1755 - A MASSIVE POST-AGE STAR EVOLVING INTO THE PLANETARY-NEBULA STAGE

Autor: RIERA, A, GARCIALARIO, P, MANCHADO, A, POTTASCH, [No Value], RAGA, AC

Publikováno v: Astronomy & astrophysics, 302(1), 137-153. EDP Sciences

IRAS 17423-1755 has been recognized as a new bipolar nebula during a multi-wavelength observational program of unidentified IRAS sources with far infrared colours similar to those of known planetary nebulae. B, V, R and H alpha CCD images show a clea

FADING AND VARIATIONS IN THE SPECTRUM OF THE CENTRAL STAR OF THE VERY YOUNG PLANETARY-NEBULA SAO-244567 (HEN-1357)

Autor: PARTHASARATHY, M, GARCIALARIO, P, DEMARTINO, D, POTTASCH, [No Value], KILKENNY, D, MARTINEZ, P, SAHU, KC, REDDY, BE, SEWELL, BT

The optical spectrum of SAO 244567 obtained in 1971 shows that it was a post-AGE B1 or B2 supergiant at that time. It has turned into a planetary nebula (PN) within the last 20 years. The IUE ultraviolet spectra obtained during the last seven years s

NEBULAR EMISSION-LINES IN IRAS 10215-5916

Autor: GARCIALARIO, P, MANCHADO, A, PARTHASARATHY, M, POTTASCH, [No Value]

Publikováno v: Astronomy & astrophysics, 285(1), 179-184. EDP Sciences

From low and high resolution spectroscopic observations of IRAS 10215 - 5916 we have discovered the presence of nebular emission lines in this G-type supergiant star in the post-AGB stage. From its high resolution spectrum we derived an expansion vel

SAO-244567 - A POST-AGB STAR WHICH HAS TURNED INTO A PLANETARY-NEBULA WITHIN THE LAST 40 YEARS

Autor: PARTHASARATHY, M, GARCIALARIO, P, POTTASCH, [No Value], MANCHADO, A, CLAVEL, J, DEMARTINO, D, VANDESTEENE, GCM, SAHU, KC

Publikováno v: Astronomy & astrophysics, 267(1), L19-L22. EDP Sciences

SAO 244567 (Hen 1357 = CPD -59(0)6926 = IRAS 17119-5926) is an IRAS source with far infrared colours and flux distribution similar to those of planetary nebulae. The IUE ultraviolet spectra obtained in July, 1988 and April 1992 show nebular emission
