Lei Chen, Attila Moor, Alexander Kreplin +7
The Herbig Ae star HD 169142 is known to have a gaseous disk with a large inner hole, and also a photometrically variable inner dust component in the sub-au region. Following up ou…
Are Inner Disc Misalignments Common? ALMA Reveals an Isotropic Outer Disc Inclination Distribution for Young Dipper Stars
M. Ansdell, E. Gaidos, C. Hedges +12
Dippers are a common class of young variable star exhibiting day-long dimmings with depths of up to several tens of percent. A standard explanation is that dippers host nearly edge…
NuSTAR/XMM-Newton monitoring of the Seyfert 1 galaxy HE 1143-1810. Testing the two-corona scenario
F. Ursini, P. -O. Petrucci, S. Bianchi +11
We test the two-corona accretion scenario for active galactic nuclei in the case of the `bare' Seyfert 1 galaxy HE 1143-1810. We perform a detailed study of the broad-band UV--X-ra…
Observing with NIKA2Pol from the IRAM 30m telescope. Early results on the commissioning phase
A. Ritacco, R. Adam, P. Ade +41
The NIKA2 polarization channel at 260 GHz (1.15 mm) has been proposed primarily to observe galactic star-forming regions and probe the critical scales between 0.01-0.05 pc at which…
Simultaneous observations of the blazar PKS2155-304 from Ultra-Violet to TeV energies

The results of the first ever contemporaneous multi-wavelength observation campaign on the BL Lac object PKS2155-304 involving Swift, NuSTAR, Fermi-LAT and H.E.S.S. are reported. T…
SUBARU Near-Infrared Imaging Polarimetry of Misaligned Disks Around The SR24 Hierarchical Triple System
Satoshi Mayama, Sebastián Pérez, Nobuhiko Kusakabe +65
The SR24 multi-star system hosts both circumprimary and circumsecondary disks, which are strongly misaligned from each other. The circumsecondary disk is circumbinary in nature. In…
H.E.S.S. and Fermi-LAT observations of PSR B1259-63/LS 2883 during its 2014 and 2017 periastron passages
H. E. S. S. Collaboration, H. Abdalla, R. Adam +222
PSR B1259-63/LS 2883 is a gamma-ray binary system consisting of a pulsar in an eccentric orbit around a bright Oe stellar-type companion star that features a dense circumstellar di…
Peering into the formation history of beta Pictoris b with VLTI/GRAVITY long baseline interferometry
GRAVITY Collaboration, M. Nowak, S. Lacour +65
Our objective is to estimate the C/O ratio in the atmosphere of beta Pictoris b and obtain an estimate of the dynamical mass of the planet, as well as to refine its orbital paramet…
A dusty benchmark brown dwarf near the ice line of HD 72946
A. -L. Maire, J. -L. Baudino, S. Desidera +12
Context. HD72946 is a bright and nearby solar-type star hosting a low-mass companion at long period (P~16 yr) detected with the radial velocities (RV) method. The companion has a m…
Chandra Observations of High Energy X-ray Sources Discovered by INTEGRAL
John A. Tomsick, Arash Bodaghee, Sylvain Chaty +6
The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite has detected in excess of 1000 sources in the ~20-100 keV band during its surveys of the sky over the past…
Spectral library of age-benchmark low-mass stars and brown dwarfs
E. Manjavacas, N. Lodieu, V. J. S. Béjar +3
In the past years, some extremely red brown dwarfs were found. They were believed to have low surface gravity, but many of their spectral characteristics were similar to those of h…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
A HARPS RV search for planets around young nearby stars
A. Grandjean, A. -M. Lagrange, M. Keppler +9
Young nearby stars are good candidates in the search for planets with both radial velocity (RV) and direct imaging techniques. This, in turn, allows for the computation of the gian…
