Star formation towards the Galactic HII region RCW120
M. Figueira, A. Zavagno, L. Deharveng +16
The expansion of HII regions can trigger the formation of stars. An overdensity of young stellar objects (YSOs) is observed at the edges of HII regions but the mechanisms that give…
Multi-wavelength campaign on NGC7469 I. The rich 640 ks RGS spectrum
Ehud Behar, Uria Peretz, Gerard A. Kriss +15
Outflows in active galaxies (AGNs) are common, although their launching mechanism, location, and physical impact on the host galaxy remain controversial. We conducted a multiwavele…
SPHERE/SHINE reveals concentric rings in the debris disk of HIP 73145
M. Feldt, J. Olofsson, A. Boccaletti +22
The debris disk of HIP73145 has been detected in scattered light in the near-IR, and at far-IR wavelengths before, but no substructure has been seen so far. Detection of such subst…
First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
Dark jets in the soft X-ray state of black hole binaries?
S. Drappeau, J. Malzac, M. Coriat +10
X-ray binary observations led to the interpretation that powerful compact jets, produced in the hard state, are quenched when the source transitions to its soft state. The aim of t…
Interferometric Evidence for Quantum Heated Particles in the Inner Region of Protoplanetary Disks around Herbig Stars
L. Klarmann, M. Benisty, M. Min +6
To understand the chemical composition of planets, it is important to know the chemical composition of the region where they form in protoplanetary disks. Due to its fundamental ro…
Broadband X-ray spectral analysis of the Seyfert 1 galaxy GRS 1734-292
A. Tortosa, A. Marinucci, G. Matt +14
We discuss the broadband X-ray spectrum of GRS 1734-292 obtained from non-simultaneous XMM-Newton and NuSTAR observations, performed in 2009 and 2014, respectively. GRS1734-292 is…
Characterization of the inner disk around HD 141569 A from Keck/NIRC2 L-band vortex coronagraphy
Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
3D Radiation Non-ideal Magnetohydrodynamical Simulations Of The Inner Rim In Protoplanetary Disks
M. Flock, S. Fromang, N. J. Turner +1
Many planets orbit within an AU of their stars, raising questions about their origins. Particularly puzzling are the planets found near the silicate sublimation front. We investiga…
Binaries among low-mass stars in nearby young moving groups
Markus Janson, Stephen Durkan, Stefan Hippler +5
The solar galactic neighbourhood contains a number of young co-moving associations of stars (so-called `young moving groups') with ages of ~10--150 Myr, which are prime targets for…
The temporal evolution of exposed water ice-rich areas on the surface of 67P/Churyumov-Gerasimenko: spectral analysis
A. Raponi, M. Ciarniello, F. Capaccioni +16
Water ice-rich patches have been detected on the surface of comet 67P/Churyumov-Gerasimenko by the VIRTIS hyperspectral imager on-board the Rosetta spacecraft, since the orbital in…
Multiplicity and clustering in Taurus star-forming region. I. Unexpected ultra-wide pairs of high-order multiplicity in Taurus
Isabelle Joncour, Gaspard Duchêne, Estelle Moraux
We collected the multiplicity data of stars in Taurus to build an up-to-date stellar/multiplicity catalog. After a general study of nearest-neighbor statistics on spatial random di…
Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
H. E. S. S. Collaboration, :, H. Abdalla +332
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies. The lowest energy threshold is obtained using monosc…
Discovery of a low-mass companion inside the debris ring surrounding the F5V star HD206893
Julien Milli, Pascale Hibon, Valentin Christiaens +30
Uncovering the ingredients and the architecture of planetary systems is a very active field of research that has fuelled many new theories on giant planet formation, migration, com…
First Detection of Hydrogen in the β Pictoris Gas Disk
P. A. Wilson, A. Lecavelier des Etangs, A. Vidal-Madjar +6
The young and nearby star β Pictoris (β Pic) is surrounded by a debris disk composed of dust and gas known to host a myriad evaporating exocomets, planetesimals and at least one pl…
Non-thermal particle acceleration in collisionless relativistic electron-proton reconnection
G. R. Werner, D. A. Uzdensky, M. C. Begelman +2
Magnetic reconnection in relativistic collisionless plasmas can accelerate particles and power high-energy emission in various astrophysical systems. Whereas most previous studies…
Global simulations of protoplanetary disks with net magnetic flux: I. Non-ideal MHD case
William Béthune, Geoffroy Lesur, Jonathan Ferreira
The planet-forming region of protoplanetary disks is cold, dense, and therefore weakly ionized. For this reason, magnetohydrodynamic (MHD) turbulence is thought to be mostly absent…
Upper limits for Mass and Radius of objects around Proxima Cen from SPHERE/VLT
D. Mesa, A. Zurlo, J. Milli +36
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Cen…
