Seasonal Evolution of Saturn's Polar Temperatures and Composition
Leigh N. Fletcher, P. G. J. Irwin, J. A. Sinclair +7
The seasonal evolution of Saturn's polar atmospheric temperatures and hydrocarbon composition is derived from a decade of Cassini Composite Infrared Spectrometer (CIRS) 7-16 m t…
New insights on Saturn's formation from its nitrogen isotopic composition
Olivier Mousis, Jonathan I. Lunine, Leigh N. Fletcher +4
The recent derivation of a lower limit for the N/N ratio in Saturn's ammonia, which is found to be consistent with the Jovian value, prompted us to revise models of S…
Ideas for Citizen Science in Astronomy
Philip J. Marshall, Chris J. Lintott, Leigh N. Fletcher
We review the relatively new, internet-enabled, and rapidly-evolving field of citizen science, focusing on research projects in stellar, extragalactic and solar system astronomy th…
The Transit Spectra of Earth and Jupiter
Patrick G. J. Irwin, Joanna K. Barstow, Neil E. Bowles +3
In recent years, a number of observations have been made of the transits of 'Hot Jupiters', such as HD 189733b, which have been modelled to derive atmospheric structure and composi…
Mid-Infrared Spectroscopy of Uranus from the Spitzer Infrared Spectrometer: 1. Determination of the Mean Temperature Structure of the Upper Troposphere and Stratosphere
Glenn S. Orton, Leigh N. Fletcher, Julianne I. Moses +7
On 2007 December 16-17, spectra were acquired of the disk of Uranus by the Spitzer Infrared Spectrometer (IRS) when its equator was close to the sub-earth point. This spectrum prov…
Exoplanet atmospheres with EChO: spectral retrievals using EChOSim
Joanna K. Barstow, Neil E. Bowles, Suzanne Aigrain +4
We demonstrate the effectiveness of the Exoplanet Characterisation Observatory mission concept for constraining the atmospheric properties of hot and warm gas giants and super Eart…
The Origin of Nitrogen on Jupiter and Saturn from the N/N Ratio
Leigh N. Fletcher, Thomas K. Greathouse, Glenn S. Orton +4
The Texas Echelon cross Echelle Spectrograph (TEXES), mounted on NASA's Infrared Telescope Facility (IRTF), was used to map mid-infrared ammonia absorption features on both Jupiter…
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…
Clouds on the hot Jupiter HD189733b: constraints from the reflection spectrum
Joanna K. Barstow, Suzanne Aigrain, Patrick G. J. Irwin +4
The hot Jupiter HD 189733b is probably the best studied of the known extrasolar planets, with published transit and eclipse spectra covering the near UV to mid-IR range. Recent wor…
Exploring the Diversity of Jupiter-Class Planets (Discussion Meeting Contribution)
Leigh N. Fletcher, Patrick G. J. Irwin, Joanna K. Barstow +3
Royal Society Discussion Meeting (2013) `Characterizing exoplanets'. Of the 900+ confirmed exoplanets discovered since 1995 for which we have constraints on their mass (i.e., not i…
