Exploring the Dust Content of Galactic Winds with Herschel. I. NGC 4631

Autor: Meléndez, M., Veilleux, S., Martin, C., Engelbracht, C., Bland-Hawthorn, J., Cecil, G., Heitsch, F., McCormick, A., Müller, T., Rupke, D., Teng, S. H.

We present a detailed analysis of deep far-infrared observations of the nearby edge-on star-forming galaxy NGC 4631 obtained with the Herschel Space Observatory. Our PACS images at 70 and 160 um show a rich complex of filaments and chimney-like featu

The wind of W Hya as seen by Herschel - I. The CO envelope

Publikováno v: A&A 561A (2014) 5-17

Asymptotic giant branch (AGB) stars lose their envelopes by means of a stellar wind whose driving mechanism is not understood well. Characterizing the composition and thermal and dynamical structure of the outflow provides constraints that are essent

The enigmatic nature of the circumstellar envelope and bow shock surrounding Betelgeuse as revealed by Herschel. I. Evidence of clumps, multiple arcs, and a linear bar-like structure

Context. The interaction between stellar winds and the interstellar medium (ISM) can create complex bow shocks. The photometers on board the Herschel Space Observatory are ideally suited to studying the morphologies of these bow shocks. Aims. We aim

Large-scale environments of binary AGB stars probed by Herschel - I. Morphology statistics and case studies of R Aquarii and W Aquilae

Autor: Mayer, A., Jorissen, A., Kerschbaum, F., Ottensamer, R., Nowotny, W., Cox, N. L. J., Aringer, B., Blommaert, J. A. D. L., Decin, L., van Eck, S., Gail, H. -P., Groenewegen, M. A. T., Kornfeld, K., Mecina, M., Posch, Th., Vandenbussche, B., Waelkens, C.

The Mass loss of Evolved StarS (MESS) sample offers a selection of 78 Asymptotic Giant Branch (AGB) stars and Red Supergiants (RSGs) observed with the PACS photometer on-board Herschel at 70 and 160 {\mu}m. For most of these objects, the dusty AGB wi

Physical conditions in the gas phases of the giant HII region LMC-N11 unveiled by Herschel - I. Diffuse [CII] and [OIII] emission in LMC-N11B

Autor: Lebouteiller, V., Cormier, D., Madden, S. C., Galliano, F., Indebetouw, R., Abel, N., Sauvage, M., Hony, S., Contursi, A., Poglitsch, A., Remy, A., Sturm, E., Wu, R.

(Abridged) The Magellanic Clouds provide a nearby laboratory for metal-poor dwarf galaxies. The low dust abundance enhances the penetration of UV photons into the interstellar medium (ISM), resulting in a relatively larger filling factor of the ioniz

Evolution of dust in the Orion Bar with Herschel: I. Radiative transfer modelling

Autor: Arab, Heddy, Abergel, Alain, Habart, Emilie, Bernard-Salas, Jeronimo, Ayasso, Hacheme, Dassas, Karin, Martin, Peter G., White, Glenn J.

Interstellar dust is a key element in our understanding of the interstellar medium and star formation. The manner in which dust populations evolve with the excitation and the physical conditions is a first step in the comprehension of the evolution o
