A fifth companion in the HR 8799 system revealed by Gaia

A. -M. Lagrange, K. Gozdziewski, F. Kiefer +5

HR 8799 is the benchmark young multi-planet system, hosting four directly imaged giant planets orbiting between a warm inner belt and a cold outer debris ring. However, the few-au…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains

J. Olofsson, M. R. Jankovic, S. Marino +22

The dust observed in debris disks is the result of a collisional cascade initiated from km-sized parent bodies. Using near-infrared to sub-millimeter observations, we can pr…

Revealing asymmetrical dust distribution in the inner regions of HD 141569

Garima Singh, Trisha Bhowmik, Anthony Boccaletti +42

We obtained polarimetric differential imaging of a gas-rich debris disk around HD 141569A with SPHERE in the H-band to compare the scattering properties of the innermost ring at 44…

HD 117214 debris disk: scattered-light images and constraints on the presence of planets

N. Engler, C. Lazzoni, R. Gratton +34

We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed…

Spatially resolved spectroscopy of the debris disk HD 32297: Further evidence of small dust grains

T. Bhowmik, A. Boccaletti, P. Thébault +14

Spectro-photometry of debris disks in total intensity and polarimetry can provide new insight into the properties of the dust grains therein (size distribution and optical properti…

A multi-wavelength study of the debris disc around 49 Cet

Nicole Pawellek, Attila Moór, Julien Milli +17

In a multi-wavelength study of thermal emission and scattered light images we analyse the dust properties and structure of the debris disc around the A1-type main sequence star 49~…
