Far-infrared Herschel/PACS images at 70 and 160 micron of a sample of 78 Galactic evolved stars are used to study the (dust) emission structures, originating from stellar wind-ISM interaction. In addition, two-fluid hydrodynamical simulations of the coupled gas and dust in wind-ISM interactions are used to compare with the observations. Four distinct classes of wind-ISM interaction (i.e. "fermata", "eyes", "irregular", and "rings") are identified and basic parameters affecting the morphology… Expand
A comprehensive search for stellar bowshock nebulae in the Milky Way: a catalog of 709 mid-infrared selected candidates
We identify 709 arc-shaped mid-infrared nebula in 24 micron Spitzer Space Telescope or 22 micron Wide Field Infrared Explorer surveys of the Galactic Plane as probable dusty interstellar bowshocksExpand
The double dust envelopes of R coronae borealis stars
The existence of extended, cold dust envelopes surrounding R Coronae Borealis (RCB) stars has been known about for over 30 years. RCB stars are an exotic group of extremely hydrogen-deficient,Expand

A Herschel study of AGB stars in the Milky Way
The Asymptotic Giant Branch (AGB) stars are low to intermediate-mass post-MS stars that undergo thermal pulses characterized by a strong wind-driven mass loss from its surface into the interstellarExpand
First Detection of Ultraviolet Emission from a Detached Dust Shell: Galaxy Evolution Explorer Observations of the Carbon Asymptotic Giant Branch Star U Hya

Modelling the carbon AGB star R Sculptoris: Constraining the dust properties in the detached shell based on far-infrared and sub-millimeter observations
Context. On the asymptotic giant branch (AGB), Sun-like stars lose a large portion of their mass in an intensive wind and enrich the surrounding interstellar medium with nuclear processed stellarExpand
On the stability of bow shocks generated by red supergiants: the case of IRC -10414.
In this Letter, we explore the hypothesis that the smooth appearance of bow shocks around some red supergiants (RSGs) might be caused by the ionization of their winds by external sources ofExpand
Late stages of stellar evolution – Herschel’s contributions ☆
Abstract Cool objects glow in the infrared. The gas and solid-state species that escape the stellar gravitational attraction of evolved late-type stars in the form of a stellar wind are cool, withExpand


The interface between the stellar wind and interstellar medium around R Cassiopeiae revealed by far-infrared imaging
Aims. The circumstellar dust shells of intermediate initial-mass (∼ 1t o 8M� ) evolved stars are generated by copious mass loss during the asymptotic giant branch phase. The density structure ofExpand
