HD 189733 A b heat map scaled one in one billion by tato_713

Last crawled date: 3 years, 3 months ago

This is the first exoplanet with its global surface mapped in any way. The map is an infrared emission map, that is the radiation from its surface temperature. It has nothing to do with global shape or topography; it is a tidal locked gas planet, so its true shape is spherical, more spherical than Solar System gas giant Jupiter or Saturn, since its longer rotational period. It could be assumed that while hotter the place, more inflated the atmosphere is, so higher is the relief. If this is true, the topography in this model is still extremely exaggerated to make it more noticeable, about 15% of the radius, giving the model an egg shape. The star-facing direction (since it is tidal locked) of every model in this post is the positive X-axis. For Earth sized exoplanets, see this.
The file's names explained: name_1_x_10_y.stl is 1 : x * 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.
HD 189733 A b

This is the closest know transiting hot Jupiter, about 1.14 times Jupiter's diameter, and it's one of the best studied of this kind of planet. A hot Jupiter is a planet of jovian size (bigger than Saturn) that orbits very close to its star. It's tidal locked, as expected in planets orbiting that close. It orbit the main star of a binary system, a orange K-type star and a red M-type dwarf. The infrared emission indicates that the hottest longitude is 30° west to the star-facing meridian. This is because the day to night gas redistribution; with winds up to supersonic speeds. By the spectre of the planet, is know to be blue, and it's probably sign of presence of silicate material within its atmosphere. This led to the speculation that it may have "rains of molten glass" within it. This planet has the most depth transit of its star viewed from Earth, and it was possible to detect the volatile escaping from it.
