Comet-like mineralogy of olivine crystals in an extrasolar proto-Kuiper belt
B. L. de Vries, B. Acke, J. A. D. L. Blommaert +20
Some planetary systems harbour debris disks containing planetesimals such as asteroids and comets. Collisions between such bodies produce small dust particles, the spectral feature…
Search for Super Earths by Timing of Transits with CoRoT
J. Cabrera
We explore the possibility of detecting Super Earths via transit timing variations with the satellite CoRoT.
An upper limit for the water outgassing rate of the main-belt comet 176P/LINEAR observed with Herschel/HIFI
M. de Val-Borro, L. Rezac, P. Hartogh +15
176P/LINEAR is a member of the new cometary class known as main-belt comets (MBCs). It displayed cometary activity shortly during its 2005 perihelion passage that may be driven by…
Submillimetric spectroscopic observations of volatiles in comet C/2004 Q2 (Machholz)
M. de Val-Borro, P. Hartogh, C. Jarchow +6
We aim to determine the production rates of several parent and product volatiles and the 12C/13C isotopic carbon ratio in the long-period comet C/2004 Q2 (Machholz), which is likel…
A chemical model for the atmosphere of hot Jupiters
Olivia Venot, Eric Hébrard, Marcelino Agùndez +5
Our purpose is to release a chemical network, and the associated rate coefficients, developed for the temperature and pressure range relevant to hot Jupiters atmospheres. Using thi…
Nano dust impacts on spacecraft and boom antenna charging
Filippo Pantellini, Soraya Belheouane, Nicole Meyer-Vernet +1
High rate sampling detectors measuring the potential difference between the main body and boom antennas of interplanetary spacecraft have been shown to be efficient means to measur…
