Apocenter pile-up and arcs: a narrow dust ring around HD 129590
Johan Olofsson, Philippe Thébault, Amelia Bayo +6
Observations of debris disks have significantly improved over the past decades, both in terms of sensitivity and spatial resolution. At near-infrared wavelengths, new observing str…
The vertical structure of debris disks and the impact of gas
Johan Olofsson, Philippe Thébault, Quentin Kral +10
The vertical structure of debris disks provides clues about their dynamical evolution and the collision rate of the unseen planetesimals. Thanks to the ever-increasing angular reso…
ISPY -- NACO Imaging Survey for Planets around Young stars: Survey description and results from the first 2.5 years of observations
R. Launhardt, Th. Henning, A. Quirrenbach +21
The occurrence rate of long-period giant planets around young stars is highly uncertain since it is not only governed by the protoplanetary disc structure and planet formation proc…
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…
An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
ISPY -- NaCo Imaging Survey for Planets around Young stars. Discovery of an M dwarf in the gap between HD 193571 and its debris ring
Arianna Musso Barcucci, Ralf Launhardt, Grant M. Kennedy +19
Context. The interaction between low-mass companions and the debris discs they reside in is still not fully understood. A debris disc can evolve due to self-stirring, a process in…
Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b
A. C. Cheetham, M. Samland, S. S. Brems +38
HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…
