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…
Interferometric Evidence for Quantum Heated Particles in the Inner Region of Protoplanetary Disks around Herbig Stars
L. Klarmann, M. Benisty, M. Min +6
To understand the chemical composition of planets, it is important to know the chemical composition of the region where they form in protoplanetary disks. Due to its fundamental ro…
3D Radiation Non-ideal Magnetohydrodynamical Simulations Of The Inner Rim In Protoplanetary Disks
M. Flock, S. Fromang, N. J. Turner +1
Many planets orbit within an AU of their stars, raising questions about their origins. Particularly puzzling are the planets found near the silicate sublimation front. We investiga…
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…
Upper limits for Mass and Radius of objects around Proxima Cen from SPHERE/VLT
D. Mesa, A. Zurlo, J. Milli +36
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Cen…
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…
