The genealogical tree of ethanol: gas-phase formation of glycolaldehyde, acetic acid and formic acid
Dimitrios Skouteris, Nadia Balucani, Cecilia Ceccarelli +5
Despite the harsh conditions of the interstellar medium, chemistry thrives in it, especially in star forming regions where several interstellar complex organic molecules (iCOMs) ha…
Anatomy of the AGN in NGC 5548 IX. Photoionized emission features in the soft X-ray spectra
Junjie Mao, J. S. Kaastra, M. Mehdipour +10
The X-ray narrow emission line region (NELR) of the archetypal Seyfert 1 galaxy NGC\,5548 has been interpreted as a single-phase photoionized plasma that is absorbed by some of the…

We report 885m ALMA continuum flux densities for 24 Taurus members spanning the stellar/substellar boundary, with spectral types from M4 to M7.75. Of the 24 systems, 22 are dete…
New spectro-photometric characterization of the substellar object HR 2562 B using SPHERE
D. Mesa, J. -L. Baudino, B. Charnay +32
HR2562 is an F5V star located at ~33 pc from the Sun hosting a substellar companion that was discovered using the GPI instrument. The main objective of the present paper is to prov…
Predictions of planet detections with near infrared radial velocities in the up-coming SPIRou Legacy Survey-Planet Search
Ryan Cloutier, Étienne Artigau, Xavier Delfosse +8
The SPIRou near infrared spectro-polarimeter is destined to begin science operations at the Canada-France-Hawaii Telescope in mid-2018. One of the instrument's primary science goal…
Orbital misalignment of the Neptune-mass exoplanet GJ 436b with the spin of its cool star
Vincent Bourrier, Christophe Lovis, Hervé Beust +12
The angle between the spin of a star and its planets' orbital planes traces the history of the planetary system. Exoplanets orbiting close to cool stars are expected to be on circu…
The lithium-rotation connection in the 125 Myr-old Pleiades cluster
J. Bouvier, D. Barrado, E. Moraux +9
The evolution of lithium abundance over a star's lifetime is indicative of transport processes operating in the stellar interior. We revisit the relationship between lithium conten…
A search for pre- and proto-brown dwarfs in the dark cloud Barnard 30 with ALMA
N. Huélamo, I. de Gregorio-Monsalvo, A. Palau +8
In this work we present ALMA continuum observations at 880 m of 30 sub-mm cores previously identified with APEX/LABOCA at 870m in the Barnard 30 cloud. The main goal is to ch…
Direct imaging of an ultracool substellar companion to the exoplanet host star HD 4113A
A. Cheetham, D. Ségransan, S. Peretti +7
Using high-contrast imaging with the SPHERE instrument at the VLT, we report the first images of a cold brown dwarf companion to the exoplanet host star HD4113A. The brown dwarf HD…
SPIRou Input Catalogue: Global properties of 440 M dwarfs observed with ESPaDOnS at CFHT
Pascal Fouqué, Claire Moutou, Lison Malo +13
Present and future high-precision radial-velocity spectrometers dedicated to the discovery of low-mass planets orbiting low-mass dwarfs need to focus on the best selected stars to…
Nitrogen oxide in protostellar envelopes and shocks: the ASAI survey
C. Codella, S. Viti, B. Lefloch +8
The high-sensitivity of the IRAM 30-m ASAI unbiased spectral survey in the mm-window allows us to detect NO emission towards both the Class I object SVS13-A and the protostellar ou…
HD 156324: a tidally locked magnetic triple spectroscopic binary with a disrupted magnetosphere
M. Shultz, Th. Rivinius, G. A. Wade +3
HD 156324 is an SB3 (B2V/B5V/B5V) system in the Sco OB4 association. The He-strong primary possesses both a strong magnetic field, and H emission believed to originate in its Ce…
Supervised detection of exoplanets in high-contrast imaging sequences
Carlos Alberto Gomez Gonzalez, Olivier Absil, Marc van Droogenbroeck
Post-processing algorithms play a key role in pushing the detection limits of high-contrast imaging (HCI) instruments. State-of-the-art image processing approaches for HCI enable t…
