Expected performances of the Characterising Exoplanet Satellite (CHEOPS). I. Photometric performances from ground-based calibration
Adrien Deline, Didier Queloz, Bruno Chazelas +6
The Characterising Exoplanet Satellite (CHEOPS) is a space mission designed to perform photometric observations of bright stars to obtain precise radii measurements of transiting p…
Formation of bi-lobed shapes by sub-catastrophic collisions: A late origin of comet 67P/C-G's structure
M. Jutzi, W. Benz
The origin of the particular shape of a small body like comet 67P/Churyumov-Gerasimenko (67P/C-G) is a topic of active research. How and when it acquired its peculiar characteristi…
How primordial is the structure of comet 67P/C-G? Combined collisional and dynamical models suggest a late formation
M. Jutzi, W. Benz, A. Toliou +2
There is an active debate about whether the properties of comets as observed today are primordial or, alternatively, if they are a result of collisional evolution or other processe…
Planet Population Synthesis
W. Benz, S. Ida, Y. Alibert +2
With the increasing number of exoplanets discovered, statistical properties of the population as a whole become unique constraints on planet formation models provided a link betwee…
The PLATO 2.0 Mission
H. Rauer, C. Catala, C. Aerts +159
PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it…
CHEOPS: A Transit Photometry Mission for ESA's Small Mission Programme
C. Broeg, A. Fortier, D. Ehrenreich +18
Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag pho…
Planet formation models: the interplay with the planetesimal disc
A. Fortier, Y. Alibert, F. Carron +2
According to the sequential accretion model, giant planet formation is based first on the formation of a solid core which, when massive enough, can gravitationally bind gas from th…
Dust-trapping Rossby vortices in protoplanetary disks
H. Meheut, Z. Meliani, P. Varniere +1
One of the most challenging steps in planet formation theory is the one leading to the formation of planetesimals of kilometre size. A promising scenario involves the existence of…
Formation and long-term evolution of 3D vortices in protoplanetary discs
H. Meheut, R. Keppens, F. Casse +1
In the context of planet formation, anticyclonic vortices have recently received lots of attention for the role they can play in planetesimals formation. Radial migration of interm…
Application of recent results on the orbital migration of low mass planets: convergence zones
C. Mordasini, K. -M. Dittkrist, Y. Alibert +3
Previous models of the combined growth and migration of protoplanets needed large ad hoc reduction factors for the type I migration rate as found in the isothermal approximation. I…
CoRoT-10b: a giant planet in a 13.24 day eccentric orbit
A. S. Bonomo, A. Santerne, R. Alonso +47
The space telescope CoRoT searches for transiting extrasolar planets by continuously monitoring the optical flux of thousands of stars in several fields of view. We report the disc…
Numerical simulations of impacts involving porous bodies: I. Implementing sub-resolution porosity in a 3D SPH Hydrocode
M. Jutzi, W. Benz, P. Michel
In this paper, we extend our Smooth Particle Hydrodynamics (SPH) impact code to include the effect of porosity at a sub-resolution scale by adapting the so-called model.…
Sungrazing comets: Properties of nuclei and in-situ detectability of cometary ions at 1 AU
M. Iseli, M. Kueppers, W. Benz +1
A one dimensional sublimation model for cometary nuclei is used to derive size limits for the nuclei of sungrazing comets, and to estimate oxygen ion fluxes at 1 AU from their evap…
A new Monte Carlo code for star cluster simulations: I. Relaxation
Marc Freitag, Willy Benz
We have developed a new simulation code aimed at studying the stellar dynamics of a galactic central star cluster surrounding a massive black hole. In order to include all the rele…
Multiple Outflow Episodes from Protostars:3-D Models of Intermittent Jets
E. M. de Gouveia Dal Pino, W. Benz
Short abstract: We present fully 3-D simulations of supersonic, radiatively cooling intermittent jets with intermediate and long variability periods (that is, periods of the order…
Momentum Transfer by Astrophysical Jets
L. Chernin, C. Masson, E. M. Gouveia Dal Pino +1
We have used 3-D smoothed particle hydrodynamical simulations to study the basic properties of the outflow that is created by a protostellar jet in a dense molecular cloud. The dyn…
