Abstract:
Colour-magnitude diagrams form a traditional way of presenting
luminous objects in the Universe and compare them to each other. Here,
we estimate the photometric distance of 44 transiting exoplanetary
systems. Parallaxes for seven systems confirm our methodology.
Combining those measurements with fluxes obtained while planets were
occulted by their host stars, we compose colour-magnitude diagrams in
the near and mid-infrared. When possible, planets are plotted
alongside very low mass stars and field brown dwarfs, who often share
similar sizes and equilibrium temperatures. They offer a natural,
empirical, comparison sample. We also include directly imaged
exoplanets and the expected loci of pure blackbodies. Irradiated
planets do not match blackbodies; their emission spectra are not
featureless. For a given luminosity, hot Jupiters' daysides show a
larger variety in colour than brown dwarfs do and display an
increasing diversity in colour with decreasing intrinsic luminosity.
The presence of an extra absorbent within the 4.5µm band would
reconcile outlying hot Jupiters with ultra-cool dwarfs' atmospheres.
Measuring the emission of gas giants cooler than 1000K would
disentangle whether planets' atmospheres behave more similarly to
brown dwarfs' atmospheres than to blackbodies, whether they are akin
to the young directly imaged planets, or if irradiated gas giants form
their own sequence.
