Carriers of the mid-IR emission bands in PNe reanalysed. Evidence of a link between circumstellar and interstellar aromatic dust
C. Joblin, R. Szczerba, O. Berne +1
It has been shown that the diversity of the aromatic emission features can be rationalized into different classes of objects, in which differences between circumstellar and interst…
HST Snapshot Survey of Post-AGB Objects
N. Siodmiak, M. Meixner, T. Ueta +3
The results from a Hubble Space Telescope (HST) snapshot survey of post-AGB objects are shown. The aim of the survey is to complement existing HST images of PPN and to connect vari…
Mixed chemistry phenomenon during late stages of stellar evolution
R. Szczerba, M. R. Schmidt, M. Pulecka
We discuss phenomenon of simultaneous presence of O- and C-based material in surroundings of evolutionary advanced stars. We concentrate on silicate carbon stars and present observ…
An evolutionary catalogue of Galactic post-AGB and related objects
R. Szczerba, N. Siodmiak, G. Stasinska +1
With the ongoing AKARI infrared sky survey, of much greater sensitivity than IRAS, a wealth of post-AGB objects may be discovered. It is thus time to organize our present knowledge…
Detached shells as tracers of AGB-ISM bow shocks
C. J. Wareing, Albert A. Zijlstra, Angela K. Speck +10
New Spitzer imaging observations have revealed the structure around the Mira variable star R Hya to be a one-sided parabolic arc 100 arcsec to the West stretching from North to Sou…
Detection of a Far-Infrared Bow-Shock Nebula Around R Hya: the First MIRIAD Results
T. Ueta, A. K. Speck, R. E. Stencel +10
We present the first results of the MIRIAD (MIPS [Multiband Imaging Photometer for Spitzer] Infra-Red Imaging of AGB [asymptotic giant branch] Dustshells) project using the Spitzer…
