A self-consistent orbital architecture for GG Tau A. I. Simultaneous orbital fitting of the hierarchical triple
A. Lacquement, H. Beust, G. Duchêne +4
GG Tau is a young triple system with the close pair, --, and , surrounded by a massive circumtriple disk with a large inner cavity difficult to explain in a bin…
The hybrid disks: a search and study to better understand evolution of disks
J. Pericaud, E. Di Folco, A. Dutrey +2
The increased sensitivity of millimeter-wave facilities now makes possible the detection of low amounts of gas in debris disks. Some of the gas-rich debris disks harbor peculiar pr…
The shadow of the Flying Saucer: A very low temperature for large dust grains
S. Guilloteau, V. Piétu, E. Chapillon +6
Dust determines the temperature structure of protoplanetary disks. However, dust temperature determinations almost invariably rely on a complex modeling of the Spectral Energy Dist…
HD141569A: disk dissipation caught in action
J. Péricaud, E. Di Folco, A. Dutrey +3
Debris disks are usually thought to be gas-poor, the gas being dissipated by accretion or evaporation during the protoplanetary phase. HD141569A is a 5 Myr old star harboring a fam…
The masses of young stars: CN as a probe of dynamical masses
S. Guilloteau, M. Simon, V. Piétu +4
Aims: We attempt to determine the masses of single or multiple young T Tauri and HAeBe stars from the rotation of their Keplerian disks. Methods:We used the IRAM PdBI interferomete…
GG Tau: the fifth element
E. Di Folco, A. Dutrey, J. -B. Le Bouquin +9
We aim at unveiling the observational imprint of physical mechanisms that govern planetary formation in young, multiple systems. In particular, we investigate the impact of tidal t…
A near-infrared interferometric survey of debris disc stars. III. First statistics based on 42 stars observed with CHARA/FLUOR
O. Absil, D. Defrère, V. Coudé du Foresto +17
(Abridged) Dust is expected to be ubiquitous in extrasolar planetary systems owing to the dynamical activity of minor bodies. Inner dust populations are, however, still poorly know…
High-sensitivity search for clumps in the Vega Kuiper-belt. New PdBI 1.3mm observations
Vincent Piétu, Emmanuel Di Folco, Stéphane Guilloteau +2
Previous studies have found that Vega is surrounded by an extended debris disc that is very smooth in the far infrared, but displays possible clumpiness at 850micron and dust emiss…
An interferometric study of the Fomalhaut inner debris disk. I. Near-infrared detection of hot dust with VLTI/VINCI
Olivier Absil, Bertrand Mennesson, Jean-Baptiste Le Bouquin +3
The innermost parts of dusty debris disks around main sequence stars are currently poorly known due to the high contrast and small angular separation with their parent stars. Using…
