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…
Atomic Gas in Debris Discs
Antonio S. Hales, M. J. Barlow, I. A. Crawford +1
We have conducted a search for optical circumstellar absorption lines in the spectra of 16 debris disc host stars. None of the stars in our sample showed signs of emission line act…
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…
The SHARDDS survey: first resolved image of the HD114082 debris disk in Lower Centaurus Crux with SPHERE
Zahed Wahhaj, Julien Milli, Grant Kennedy +17
We present the first resolved image of the debris disk around the 16+/-8 Myr old star, HD 114082. The observation was made in the H-band using the SPHERE instrument. The star is at…
ALMA observations of the Corvi debris disc: inward scattering of CO-rich exocomets by a chain of 3-30 M planets?
S. Marino, M. C. Wyatt, O. Panic +10
While most of the known debris discs present cold dust at tens of AU, a few young systems exhibit hot dust analogous to the Zodiacal dust. Corvi is particularly interesting as…
Exocometary gas structure, origin and physical properties around Pictoris through ALMA CO multi-transition observations
L. Matrà, W. R. F. Dent, M. C. Wyatt +9
Recent ALMA observations unveiled the structure of CO gas in the 23 Myr-old Pictoris planetary system, a component that has been discovered in many similarly young debris disks…
