First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
Discovery of a low-mass companion inside the debris ring surrounding the F5V star HD206893
Julien Milli, Pascale Hibon, Valentin Christiaens +30
Uncovering the ingredients and the architecture of planetary systems is a very active field of research that has fuelled many new theories on giant planet formation, migration, com…
Inner mean-motion resonances with eccentric planets: A possible origin for exozodiacal dust clouds
Virginie Faramaz, Steve Ertel, Mark Booth +2
High levels of dust have been detected in the immediate vicinity of many stars, both young and old. A promising scenario to explain the presence of this short-lived dust is that th…
The influence of dust grain porosity on the analysis of debris disc observations
Robert Brunngräber, Sebastian Wolf, Florian Kirchschlager +1
Debris discs are often modelled assuming compact dust grains, but more and more evidence for the presence of porous grains is found. We aim at quantifying the systematic errors int…
Exocomet signatures around the A-shell star Leo?
C. Eiroa, I. Rebollido, B. Montesinos +18
We present an intensive monitoring of high-resolution spectra of the Ca {\sc ii} K line in the A7IV shell star Leo at very short (minutes, hours), short (night to night), and m…
Resolved astrometric orbits of ten O-type binaries
J. -B. Le Bouquin, H. Sana, E. Gosset +11
Our long term aim is to derive model-independent stellar masses and distances for long period massive binaries by combining apparent astrometric orbit with double-lined radial velo…
A near-infrared interferometric survey of debris-disc stars. V. PIONIER search for variability
S. Ertel, D. Defrère, O. Absil +10
Context: Extended circumstellar emission has been detected within a few 100 milli-arcsec around > 10% of nearby main sequence stars using near-infrared interferometry. Follow-up ob…
Simultaneous Water Vapor and Dry Air Optical Path Length Measurements and Compensation with the Large Binocular Telescope Interferometer
D. Defrère, P. Hinz, E. Downey +14
The Large Binocular Telescope Interferometer uses a near-infrared camera to measure the optical path length variations between the two AO-corrected apertures and provide high-angul…
Incidence of debris discs around FGK stars in the solar neighbourhood
B. Montesinos, C. Eiroa, A. V. Krivov +16
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
Polarization measurements of hot dust stars and the local interstellar medium
J. P. Marshall, D. V. Cotton, K. Bott +7
Debris discs are typically revealed through excess emission at infrared wavelengths. Most discs exhibit excess at mid- and far-infrared wavelengths, analogous to the solar system's…
