THE ASTROSPHERE OF THE ASYMPTOTIC GIANT BRANCH STAR IRC+10216 [PDF]
The Astrophysical Journal, 2010 We have discovered a very extended shock structure (i.e., with a diameter of about 24 arcmin) surrounding the well-known carbon star IRC+10216 in ultraviolet images taken with the GALEX satellite. We conclude that this structure results from the interaction of IRC+10216's molecular wind with the interstellar medium (ISM), as it moves through the latter.

Evolution of the Outflow in the Water Fountain Source IRAS 18043–2116
The Astrophysical Journal, 2023 We present the spectral and spatial evolution of H _2 O masers associated with the water fountain source IRAS 18043−2116, found in observations with the Nobeyama 45 m Telescope and the Australia Telescope Compact Array. We have found new highest-velocity

Properties of the Variation of the Infrared Emission of OH/IR Stars III. The M Band Light Curves [PDF]
Journal of Astronomy and Space Sciences, 2010 To study properties of the pulsation in the infrared emission for long period variables, we have collected and analyzed the infrared observational data at M band for 12 OH/IR stars.

Backflow in post-asymptotic giant branch stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We derive the conditions for a backflow toward the central star(s) of circumstellar material to occur during the post-asymptotic giant branch (AGB) phase. The backflowing material may be accreted by the post-AGB star and/or its companion, if such exists.

Optical Spectropolarimetry of Asymptotic Giant Branch and Post–Asymptotic Giant Branch Stars
The Astrophysical Journal, 2006 Spectropolarimetric observations are presented for 21 AGB stars, 13 proto-planetary nebulae (PPNs), and two R CrB-type stars. The spectra cover the wavelength range from ~4200 to 8400 A with 16 A resolution. Among the AGB stars, 8 of 14 M giants, five of six carbon stars, and zero of one S star showed intrinsic polarization.

Pulsating stars in the VMC survey
EPJ Web of Conferences, 2017 The VISTA survey of the Magellanic Clouds system (VMC) began observations in 2009 and since then, it has collected multi-epoch data at Ks and in addition multi-band data in Y and J for a wide range of stellar populations across the Magellanic system ...

CO observations of candidates for carbon-rich asymptotic giant branch and post-asymptotic giant branch stars [PDF]
, 1993 Circumstellar CO emission has been detected in a number of featureless or weak SiC emission, low color temperature IRAS sources. The CO detections confirm the suggestion that these are either extreme carbon stars, carbon-rich proto-planetary nebulae ...
