VLT/X-shooter survey of near-infrared diffuse interstellar bands

N. L. J. Cox, J. Cami, L. Kaper +5

This paper presents a spectral survey of diffuse interstellar bands (DIBs) in the NIR range, from 0.9 to 2.5 micron. The observations were designed to detect new DIBs, confirm prev…

Confirmation of circumstellar phosphine

M. Agundez, J. Cernicharo, L. Decin +2

Phosphine (PH3) was tentatively identified a few years ago in the carbon star envelopes IRC+10216 and CRL2688 from observations of an emission line at 266.9 GHz attributable to the…

Binary white dwarfs in the halo of the Milky Way

Pim van Oirschot, Gijs Nelemans, Silvia Toonen +4

Aims: We study single and binary white dwarfs in the inner halo of the Milky Way in order to learn more about the conditions under which the population of halo stars was born, such…

Properties of extragalactic dust inferred from linear polarimetry of Type Ia Supernovae

F. Patat, S. Taubenberger, N. L. J. Cox +9

Aims: The aim of this paper is twofold: 1) to investigate the properties of extragalactic dust and compare them to what is seen in the Galaxy; 2) to address in an independent way t…

Herschel Planetary Nebula Survey (HerPlaNS) - First Detection of OH+ in Planetary Nebulae

I. Aleman, T. Ueta, D. Ladjal +15

We report the first detections of OH emission in planetary nebulae (PNe). As part of an imaging and spectroscopy survey of 11 PNe in the far-IR using the PACS and SPIRE instrum…

Dense molecular clouds in the SN2008fp host galaxy

N. L. J. Cox, F. Patat

(abridged) We use observations of interstellar absorption features, such as atomic and molecular lines as well as diffuse interstellar bands (DIBs), towards SN2008fp to study the p…

Herschel's view of the large-scale structure in the Chamaeleon dark clouds

C. Alves de Oliveira, N. Schneider, B. Merín +17

The Chamaeleon molecular cloud complex is one of the nearest star-forming sites encompassing three molecular clouds with a different star-formation history, from quiescent (Cha III…

The Herschel Exploitation of Local Galaxy Andromeda (HELGA): IV. Dust scaling relations at sub-kpc resolution

S. Viaene, J. Fritz, M. Baes +18

The imprints of dust-starlight interactions are visible in scaling relations between stellar characteristics, star formation parameters and dust properties. We aim to examine dust…

Effect of dust on Kelvin-Helmholtz instabilities

Tom Hendrix, Rony Keppens

Dust is present in a large variety of astrophysical fluids, from tori around supermassive black holes to molecular clouds, protoplanetary discs, and cometary outflows. In many such…
