Investigating the flyby scenario for the HD 141569 system
Rémy Reche, Hervé Beust, J. -C. Augereau
HD 141569, a triple star system, has been intensively observed and studied for its massive debris disk. It was rather regarded as a gravitationally bound triple system but recent m…
Extrasolar planets and brown dwarfs around A-F type stars V. A planetary system found with HARPS around the F6IV-V star HD 60532
M. Desort, A. -M. Lagrange, F. Galland +4
Aims: In the frame of the search for extrasolar planets and brown dwarfs around early-type stars, we present the results obtained for the F-type main-sequence star HD 60532 (F6V) w…
On the observability of resonant structures in planetesimal disks due to planetary migration
Rémy Reche, Hervé Beust, J. C. Augereau +1
We present a thorough study of the impact of a migrating planet on a planetesimal disk, by exploring a broad range of masses and eccentricities for the planet. We discuss the sensi…
New constrains on Gliese 86 B
A. -M. Lagrange, H. Beust, S. Udry +2
We present the results of multi epochs imaging observations of the companion to the planetary host Gliese 86. Associated to radial velocity measurements, this study aimed at charac…
Dust Production from collisions in extrasolar planetary systems The inner Beta-Pictoris disc
Philippe Thebault, Jean-Charles Augereau, Herve Beust
Dust particles observed in extrasolar planetary discs originate from undetectable km-sized bodies but this valuable information remains uninteresting if the theoretical link betwee…
VLT/NACO adaptive optics imaging of the TY CrA system - A fourth stellar component candidate detected
G. Chauvin, A-M. Lagrange, H. Beust +11
We report the detection of a possible subsolar mass companion to the triple young system TY CrA using the NACO instrument at the VLT UT4 during its commissioning. Assuming for TY C…
