The extrasolar planet GL 581 d: A potentially habitable planet?

P. von Paris, S. Gebauer, M. Godolt +6

The planetary system around the M star Gliese 581 contains at least three close-in potentially low-mass planets, GL 581 c, d, and e. In order to address the question of the habitab…

Primary and secondary eclipse spectroscopy with JWST: exploring the exoplanet parameter space

A. R. Belu, F. Selsis, J-C. Morales +3

Eclipse exoplanet spectroscopy has yielded detection of H_2O, CH_4, CO_2 and CO in the atmosphere of hot jupiters and neptunes. About 40 large terrestrial planets are announced or…

First results on Martian carbon monoxide from Herschel/HIFI observations

P. Hartogh, M. I. Błęcka, C. Jarchow +48

We report on the initial analysis of Herschel/HIFI carbon monoxide (CO) observations of the Martian atmosphere performed between 11 and 16 April 2010. We selected the (7-6) rotatio…

Herschel/HIFI observations of Mars: first detection of O_2 at submillimetre wavelengths and upper limits on HCl and H_2O_2

P. Hartogh, C. Jarchow, E. Lellouch +47

We report on an initial analysis of Herschel/HIFI observations of hydrogen chloride (HCl), hydrogen peroxide (H_2O_2), and molecular oxygen (O_2) in the Martian atmosphere performe…

On the growth and orbital evolution of giant planets in layered protoplanetary disks

Arnaud Pierens, Richard P. Nelson

We present the results of hydrodynamic simulations of the growth and orbital evolution of giant planets embedded in a protoplanetary disk with a dead-zone. The aim is to examine to…

Tidal Effects on the Habitability of Exoplanets: The Case of GJ 581 d

Rory Barnes, Brian Jackson, René Heller +2

Tides may be crucial to the habitability of exoplanets. If such planets form around low-mass stars, then those in the circumstellar habitable zone will be close enough to their hos…

First results of Herschel/PACS observations of Neptune

E. Lellouch, P. Hartogh, H. Feuchtgruber +51

We report on the initial analysis of a Herschel/PACS full range spectrum of Neptune, covering the 51-220 micrometer range with a mean resolving power of ~ 3000, and complemented by…

The Herschel-SPIRE submillimetre spectrum of Mars

B. M. Swinyard, P. Hartogh, S. Sidher +44

We have obtained the first continuous disk averaged spectrum of Mars from 450 to 1550 Ghz using the Herschel-SPIRE Fourier Transform Spectrometer. The spectrum was obtained at a co…

The Roles of Tidal Evolution and Evaporative Mass Loss in the Origin of CoRoT-7 b

Brian Jackson, Neil Miller, Rory Barnes +3

CoRoT-7 b is the first confirmed rocky exoplanet, but, with an orbital semi-major axis of 0.0172 AU, its origins may be unlike any rocky planet in our solar system. In this study,…

Is Gliese 581d habitable? Some constraints from radiative-convective climate modeling

R. Wordsworth, F. Forget, F. Selsis +3

The recently discovered exoplanet Gl581d is extremely close to the outer edge of its system's habitable zone, which has led to much speculation on its possible climate. We have per…

Searching for sub-stellar companion into the LkCa15 proto-planetary disk

M. Bonavita, G. Chauvin, A. Boccaletti +8

Recent sub-millimetric observations at the Plateau de Bure interferometer evidenced a cavity at ~ 46 AU in radius into the proto-planetary disk around the T Tauri star LkCa15 (V107…

Generalized Milankovitch Cycles and Longterm Climatic Habitability

David S. Spiegel, Sean N. Raymond, Courtney D. Dressing +2

Although the Earth's orbit is never far from circular, terrestrial planets around other stars might experience substantial changes in eccentricity that could lead to climate change…

Planet-planet scattering in planetesimal disks II: Predictions for outer extrasolar planetary systems

Sean N. Raymond, Philip J. Armitage, Noel Gorelick

We develop an idealized dynamical model to predict the typical properties of outer extrasolar planetary systems, at radii beyond 5 AU. Our hypothesis is that dynamical evolution in…
