What asteroseismology can do for exoplanets

Vincent Van Eylen, Mikkel N. Lund, Victor Silva Aguirre +12

We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of ste…

Kepler detection of a new extreme planetary system orbiting the subdwarf-B pulsator KIC10001893

R. Silvotti, S. Charpinet, E. Green +7

KIC10001893 is one out of 19 subdwarf-B (sdB) pulsators observed by the Kepler spacecraft in its primary mission. In addition to tens of pulsation frequencies in the g-mode domain,…

The Debris Disk of Solar Analogue Ceti: Herschel Observations and Dynamical Simulations of the Proposed Multiplanet System

S. M. Lawler, J. Di Francesco, G. M. Kennedy +16

Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue (Greaves et al. 2004) and possible multiplanet system (Tuomi et al. 2013) that…

Asteroseismic inference on the spin-orbit misalignment and stellar parameters of HAT-P-7

Mikkel N. Lund, Mia Lundkvist, Victor Silva Aguirre +12

The measurement of obliquities in star-planet systems is of great importance for the understanding of planet system formation and evolution. The bright and well studied HAT-P-7 sys…

Chemical modeling of exoplanet atmospheres

Olivia Venot, Marcelino Agúndez

The past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System an…

Connecting the dots: A versatile model for the atmospheres of tidally locked Super-Earths

Ludmila Carone, Rony Keppens, Leen Decin

Radiative equilibrium temperatures are calculated for the troposphere of a tidally locked Super-Earth based on a simple greenhouse model, using Solar System data as a guideline. Th…

Herschel observations of gas and dust in comet C/2006 W3 (Christensen) at 5 AU from the Sun

M. de Val-Borro, D. Bockelée-Morvan, E. Jehin +19

We aimed to measure the H2O and dust production rates in C/2006 W3 (Christensen) with the Herschel Space Observatory at a heliocentric distance of ~ 5 AU. We have searched for emis…

Scientific rationale of Saturn's in situ exploration

O. Mousis, L. N. Fletcher, J. -P. Lebreton +47

Remote sensing observations meet some limitations when used to study the bulk atmospheric composition of the giant planets of our solar system. A remarkable example of the superior…

Pseudo 2D chemical model of hot Jupiter atmospheres: application to HD 209458b and HD 189733b

Marcelino Agundez, Vivien Parmentier, Olivia Venot +2

We have developed a pseudo two-dimensional model of a planetary atmosphere, which takes into account thermochemical kinetics, photochemistry, vertical mixing, and horizontal transp…
