Photometry of Super-Jupiter 2M1207b

Photometry of Super-Jupiter 2M1207b
This graph plots small changes in the infrared brightness of a super-Jupiter as measured by the Hubble Space Telescope. The S-shaped curve is extrapolated from the data points. Its sinusoidal shape suggests that brightness changes are a result of a 10-hour rotation period (horizontal axis). The vertical axis shows small changes in brightness. This would mean that the planet likely has patchy clouds that influence the amount of infrared radiation observed as the planet rotates. At a distance of 170 light-years from Earth, the planet is too far away for Hubble to actually resolve atmospheric structure.

Artist's View of a Super-Jupiter around a Brown Dwarf (2M1207)

This is an illustration of a planet that is four times the mass of Jupiter and orbits 5 billion miles from a brown-dwarf companion (the bright red object seen in the background). The rotation rate of this "super-Jupiter" has been measured by studying subtle variations in the...

Brown Dwarf 2M1207A and Companion

[Left] – This is a Hubble Space Telescope near-infrared-light image of a brown dwarf located 170 light-years away from Earth. The object is no more than 30 times the mass of Jupiter, making it too small to sustain nuclear fusion to shine as a star. [Right] – When the glow of the...
