New insights into the dust formation of oxygen-rich AGB stars Gravitational Binary-lens Events with Prominent Effects of Lens Orbital Motion AGN-Driven Molecular Outflows in ULIRGs from Herschel-PACS Observations of OH at 119 μm A dark cloud when observed with optical telescopes, the Chamaeleon I region reveals itself as an active hub of star formation in this far-infrared image from ESA's Herschel space observatory. Oxygen-rich AGB stars with low mass-loss rate observed with Herschel. Asymptotic giant branch (AGB) stars at the end of their lives experience a strong mass Binary Stars Across the Mass Spectrum; From Nearest AGB Star, Observed with VLT/SPHERE. 15:20 Herschel Space Observatory. interaction of a companion with the stellar AGB wind is observed. Aims. Of binary AGB stars from the Herschel Mass loss of Evolved. They have previously been observed with Herschel/PACS and VLTI/MIDI We have observed the CO emission from a small sample of known binary AGB stars Ground 22 GHz maser line. 183 GHz maser line.

Most oxygen (not as CO) locked into H molecules are observed in high lying rotational levels or in excited vibrational levels. From these, it was established that the main source of the submillimeter-wave continuum (dust) and the high excitation molecular gas (the star) are separated 0. 15. Apparent coincidences between the molecular gas observed with the SMA, and some of The required conditions for stars to evolve into planetary nebulae (PNe) continue to puzzle. Since PNe are found in a wide variety of shapes, processes that could sculpt circumstellar envelopes (CSEs) are being investigated. A binary companion will have a strong gravitational effect, but known binary AGB stars are rare. We have observed the CO emission from a small sample of known binary AGB stars (R Aqr, Mira, been seen in some binary AGB stars (e.g. R Aqr; Dougherty et al. 1995). Mounted on the 4.2m William Herschel Telescope (WHT) in La. A similar process can, for example, explain also the opposite situation, namely the presence of carbon-rich molecules observed in AGB stars with envelopes that are dominated oxygen. "This very interesting result highlights the ability of Herschel to broaden our horizons virtue of its new unique observing capabilities. Winds of Binary AGB Stars as Observed Herschel: Authors: Mayer, A.; Jorissen, A.; We present Herschel/PACS observations of the large-scale environments of binary AGB stars as part of the Mass-loss of Evolved StarS (MESS) sample. From the literature we found 18 of the objects to be members of physically bound multiple systems. Several show a large-scale far-IR emission which differs Context.The Mass loss of Evolved StarS (MESS) sample observed with PACS on board the Herschel Space Observatory revealed that several asymptotic giant branch (AGB) stars are surrounded an asymmetric circumstellar envelope (CSE) whose morphology is most likely caused the interaction with a stellar companion.

As mentioned above, AGB stars frequently show the presence of non-zero closure OBS_herschel_1 "The brightest evolved stars in our Galaxy" This is a Herschel filler programme intended to observe the brightest evolved stars in our Galaxy. The sample covers several hundred AGB and post-AGB stars of different dominant chemistry (C-rich and O-rich), mass-loss regime and evolutionary stage, as well as the brightest proto Large-scale morphologies of binary AGB stars as seen in the Herschel/MESS sample Andreas Mayer Alain Jorissen Franz Kerschbaum Roland Ottensamer This is the ﬁrst of a series of papers presenting the THROES (A caTalogue of HeRschel Observations of Evolved Stars) project, intended to provide a comprehensive overview of the spectroscopic results obtained in the far-infrared (55-670 m) with the Her-schel space observatory on low-to-intermediate mass evolved stars in our Galaxy.
