Dust Growth in Binary Systems: Inhibition of dust settling and growth in circumbinary discs
Antoine Alaguero, Nicolás Cuello, Jean-François Gonzalez +4
Stellar multiplicity alters the density structure of protoplanetary discs and thereby the initial conditions for planet formation. Yet, the interplay between companion-disc interac…
ALMA millimetre-wavelength imaging of HD 138965: New constraints on the debris dust composition and presence of planetary companions
J. P. Marshall, S. Hengst, A. Trejo-Cruz +10
HD 138965 is a young A type star and member of the nearby young Argus association. This star is surrounded by a broad, bright debris disc with two temperature components that was s…
The vertical structure of debris discs and the role of disc gravity: A primer using a simplified model
Antranik A. Sefilian, Kaitlin M. Kratter, Mark C. Wyatt +4
Debris discs provide valuable insights into the formation and evolution of exoplanetary systems. Their structures are commonly attributed to planetary perturbations, serving as pro…
An impact-free mechanism to deliver water to terrestrial planets and exoplanets
Quentin Kral, Paul Huet, Camille Bergez-Casalou +3
To date, the most widespread scenario is that the Earth originated without water and was brought to the planet mainly due to impacts by wet asteroids coming from further out in spa…
The near-infrared degree of polarization in debris disks. Toward a self-consistent approach to model scattered light observations
Johan Olofsson, Philippe Thébault, Amelia Bayo +2
Debris disks give us the unique opportunity to probe the properties of small m-sized particles, allowing us to peer into the constituents of their parent bodies, young analogs o…
The polarisation properties of the HD 181327 debris ring. Evidence for sub-micron particles from scattered light observations
Julien Milli, Elodie Choquet, Ryo Tazaki +26
Polarisation is a powerful remote-sensing tool to study the nature of particles scattering the starlight. It is widely used to characterise interplanetary dust particles in the Sol…
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…
Morphology of the gas-rich debris disk around HD 121617 with SPHERE observations in polarized light
Clément Perrot, Johan Olofsson, Quentin Kral +7
Debris disks are the signposts of collisionally eroding planetesimal circumstellar belts, whose study can put important constraints on the structure of extrasolar planetary systems…
Stellar winds can affect gas dynamics in debris disks and create observable belt winds
Quentin Kral, James Pringle, Luca Matrà +1
Context: Gas is now detected in many extrasolar systems around mature stars aged between 10 Myr to 1 Gyr with planetesimal belts. Gas in these mature disks is thought to be…
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…
Hot exozodiacal dust: an exocometary origin?
Élie Sezestre, Jean-Charles Augereau, Philippe Thébault
We aim to explore two exozodiacal dust production mechanisms, first re-investigating the Poynting-Robertson drag pile-up scenario, and then elaborating on the less explored, but pr…
LIDT-DD: A new self-consistent debris disc model including radiation pressure and coupling dynamical and collisional evolution
Q. Kral, P. Thebault, S. Charnoz
The first attempt at developing a fully self-consistent code coupling dynamics and collisions to study debris discs (Kral, Thebault, Charnoz, 2013) is presented. So far, these two…
High Contrast Imaging of the Close Environment of HD 142527 -
J. Rameau, G. Chauvin, A. -M. Lagrange +4
Context. It has long been suggested that circumstellar disks surrounding young stars may be the signposts of planets, and still more since the recent discoveries of embedded subste…
