Astrochemistry at work in the L1157-B1 shock: acetaldehyde formation
C. Codella, F. Fontani, C. Ceccarelli +5
The formation of complex organic molecules (COMs) in protostellar environments is a hotly debated topic. In particular, the relative importance of the gas phase processes as compar…
Structure of the nucleus of 1928+738
J. Roland, S. Britzen, E. Kun +3
Modeling of the trajectories of VLBI components ejected by the nucleus of 1928+738 shows the VLBI jet contains three families of trajectories, i.e. VLBI components are ejected from…
The Mass-Dependence of Angular Momentum Evolution in Sun-Like Stars
Sean P. Matt, A. Sacha Brun, Isabelle Baraffe +2
To better understand the observed distributions of rotation rate and magnetic activity of sun-like and low-mass stars, we derive a physically motivated scaling for the dependence o…
H.E.S.S. detection of TeV emission from the interaction region between the supernova remnant G349.7+0.2 and a molecular cloud
H. E. S. S. Collaboration, :, A. Abramowski +224
G349.7+0.2 is a young Galactic supernova remnant (SNR) located at the distance of 11.5 kpc and observed across the entire electromagnetic spectrum from radio to high energy (HE) Ga…

Context : The properties of the inner disks of bright Herbig AeBe stars have been studied with near infrared (NIR) interferometry and high resolution spectroscopy. The continuum an…
The fiber coupler and beam stabilization system of the GRAVITY interferometer
O. Pfuhl, M. Haug, F. Eisenhauer +20
We present the installed and fully operational beam stabilization and fiber injection subsystem feeding the 2nd generation VLTI instrument GRAVITY. The interferometer GRAVITY requi…
Fast molecular jet from L1157-mm
M. Tafalla, R. Bachiller, B. Lefloch +4
L1157-mm powers a molecular outflow that is well-known for its shock-induced chemical activity in several hot-spots. We have studied the molecular emission toward L1157-mm searchin…
H.E.S.S. reveals a lack of TeV emission from the supernova remnant Puppis A
H. E. S. S. Collaboration, :, A. Abramowski +224
Puppis A is an interesting ~4 kyr-old supernova remnant (SNR) that shows strong evidence of interaction between the forward shock and a molecular cloud. It has been studied in deta…
The LEECH Exoplanet Imaging Survey. Further constraints on the planet architecture of the HR 8799 system
A. -L. Maire, A. J. Skemer, P. M. Hinz +36
Context. Astrometric monitoring of directly-imaged exoplanets allows the study of their orbital parameters and system architectures. Because most directly-imaged planets have long…
Spiral arms in scattered light images of protoplanetary discs: Are they the signposts of planets?
Attila Juhasz, Myriam Benisty, Adriana Pohl +3
One of the striking discoveries of protoplanetary disc research in recent years are the spiral arms seen in several transitional discs in polarised scattered light. An interesting…
Herschel -PACS observations of [OI] and H2O in Cha II
P. Riviere-Marichalar, A. Bayo, I. Kamp +11
Gas plays a major role in the dynamical evolution of protoplanetary discs. Its coupling with the dust is the key to our understanding planetary formation. Studying the gas content…
Diffuse Galactic gamma-ray emission with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +225
Diffuse -ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over sev…
The HARPS search for southern extra-solar planets XXXV. Planetary systems and stellar activity of the M dwarfs GJ 3293, GJ 3341, and GJ 3543
N. Astudillo-Defru, X. Bonfils, X. Delfosse +13
Context. Planetary companions of a fixed mass induce larger amplitude reflex motions around lower-mass stars, which helps make M dwarfs excellent targets for extra-solar planet sea…
Transiting exoplanets and magnetic spots characterized with optical interferometry
R. Ligi, D. Mourard, A. -M. Lagrange +2
Stellar activity causes difficulties in the characterization of transiting exoplanets. Studies have been performed to quantify its impact on infrared interferometry, but not in the…
Gas and dust structures in protoplanetary disks hosting multiple planets
P. Pinilla, M. de Juan Ovelar, S. Ataiee +4
Transition disks have dust-depleted inner regions and may represent an intermediate step of an on-going disk dispersal process, where planet formation is probably in progress. Rece…
The MiMeS Survey of Magnetism in Massive Stars: CNO surface abundances of Galactic O stars
F. Martins, A. Hervé, J. -C. Bouret +7
The evolution of massive stars is still partly unconstrained. Mass, metallicity, mass loss and rotation are the main drivers of stellar evolution. Binarity and magnetic field may a…
Anatomy of the AGN in NGC 5548: II. The Spatial, Temporal and Physical Nature of the Outflow from HST/COS Observations
N. Arav, C. Chamberlain, G. A. Kriss +30
(Abridged) Our deep multiwavelength campaign on NGC 5548 revealed an unusually strong X-ray obscuration. The resulting dramatic decrease in incident ionizing flux allowed us to con…
