The carbon star IRAS 06088+1909
We present first-time investigations, by means of several differenttechniques in the visual and infrared domains, of the source 06088+1909,discovered by the IRAS satellite and classified as a carbon star on thebasis of a SiC emission feature. Our interest for this source startedwith two lunar occultation events, which showed the presence of extendedcircumstellar emission on the scale of ~0farcs01 . Follow-upobservations by photometry, polarimetry, spectroscopy, speckleinterferometry and two more lunar occultations, have revealed manyinteresting characteristics, and in particular the presence of aflattened shell around the central star. By combining together allavailable observational evidence, we have been able to infer some of theproperties of this shell, such as its shape, size, temperature of thegrains, and mechanism of polarization. The object appears as one moreexample of the complexity existing in the environments of late-typegiants and AGB stars, similar to well-known cases such as the Egg Nebulaand the Red Rectangle. In the case of IRAS 06088+1909, it has beenpossible to conduct such a study at an unprecedented level of angularresolution. Based on observations collected at TIRGO (Gornergrat,Switzerland), and at Calar Alto (Spain). TIRGO is operated by CNR-CAISMIArcetri, Italy. Calar Alto is operated by the German-SpanishAstronomical Center.
| Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.
