The colour of giant planets in the Solar System

The colour of giant planets in the Solar System

Following our attempt to measure the colour of HD 189733b (see this post), I have taken a look at what determines the colours of Solar-System…

Future space missions on exoplanet atmospheres

Future space missions on exoplanet atmospheres

A large part of our present knowledge of exoplanet atmospheres come from observations done with the Spitzer space telescope. With this mission drawing to an end, there…

Changing views on the radius inflation of hot Jupiters

Changing views on the radius inflation of hot Jupiters

The “anomalous radius problem” The first transiting hot Jupiter, HD 209458 b, is much larger than can be accounted for by standard models of structure…

The hot Jupiter HD 209458 b

The First Known Transiting Planet HD 209458 b was the first planet confirmed using the transit method. The light dimming due to its transit was…

Changing views on spin-orbit alignment

Changing views on spin-orbit alignment

The projection of the angle between the stellar spin and the planetary orbit can be measured for transiting planets, by following the radial-velocity anomaly during…

The very hot Jupiter WASP-12 b

The very hot Jupiter WASP-12 b

Even amongst the already extreme “hot Jupiters”, WASP-12 is an extreme case. It orbits a hot F-star in only one day, which results in an…

Bloated hot Jupiters

Bloated hot Jupiters

Why are some hot Jupiters so much larger than standard models would allow? The debate on the “inflation” of hot Jupiters started right after the…

The hot Jupiter HD 189733 b

The transiting hot Jupiter HD 189733 b is one of the most favourable targets we have for measuring the structure and composition of an exoplanet’s…

Transmission Spectroscopy

Transmission Spectroscopy

Transmission spectroscopy is a technique used to gather details about the chemical composition and the extent of the atmosphere of a transiting exoplanet. As the…
