The high-albedo, low polarization disk around HD 114082 harbouring a Jupiter-sized transiting planet
N. Engler, J. Milli, R. Gratton +36
We present new optical and near-IR images of debris disk around the F-type star HD 114082. We obtained direct imaging observations and analysed the TESS photometric time series dat…
The halo around HD 32297: m-sized cometary dust
Johan Olofsson, Philippe Thébault, Grant M. Kennedy +1
The optical properties of the second generation dust that we observe in debris disks remain quite elusive, whether it is the absorption efficiencies at millimeter wavelengths or th…
ALMA's view of the M-dwarf GSC 07396-00759's edge-on debris disc: AU Mic's coeval twin
Patrick F. Cronin-Coltsmann, Grant M. Kennedy, Christian Adam +7
We present new ALMA Band 7 observations of the edge-on debris disc around the M1V star GSC 07396-00759. At ~20 Myr old and in the beta Pictoris Moving Group along with AU Mic, GSC…
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…
LBT search for companions and sub-structures in the (pre)transitional disk of AB Aurigae
Sebastián Jorquera, Mickaël Bonnefoy, Sarah Betti +18
Multi-wavelengths high-resolution imaging of protoplanetary disks has revealed the presence of multiple, varied substructures in their dust and gas components which might be signpo…
