An emerge subdivision of skill have a go at it as exometeorology is offering noteworthy insights into the conditions set up on some of the more extreme satellite in the beetleweed — include the eldritch and mind - boggingly monumental weather normal experienced on a hot Jupiter that ’s 385 light years from Earth .
Hot Jupiters are those exotic category of extrasolar planets that are very similar in size of it and make-up to Jupiter — but these massive gun colossus revolve around their parent stars at ludicrously confining distances . They ’re located anywhere from 0.015 to 0.5 AU from their Sun ( 1 AU = distance from Earth to the Sun ) .
Needless to say , the surface temperature of hot Jupiters are utmost , hence the name . And to make thing even more interesting , these planet are tidally locked ; they all sport a daylight side that ’s always facing the sun .
Looking to predict the kind of weather experienced on these planets , Nikole Lewis of MIT recently conducted an analysis of the red-hot JupiterHAT - P-2b — a planet in an flakey orbit around its sun ( it only takes 5 day or so to complete one orbit ) . She put together a kind of exoplanetary atmospheric condition map using a technique called SPARC / MITgcm that was acquire by Nick Cowan of Northwestern University .
Because these planets are tidally put away , astronomers are capable to observe their various phases , like crescent , gibbous , and full . Then , by measuring the infrared brightness of the planet during the class of its different form , they ’re able to make a rudimentary map of temperature detect at the various longitude .
Which is nothing short of unbelievable when considering just how far these planets are from Earth .
Using this technique , Lewis conclude that HAT - P-2b ’s whizz - facing side features a daytime temperature of 2,400 Kelvin ( 2,127 degree Anders Celsius ) . The night - face side , on the other hand , experience a temperature of 1,200 K ( 927 degrees Celsius ) . So even at night , this satellite is ten time hotter than Jupiter .
The 1,000 degree difference between the two side is uttermost — no doubt . This atmospheric dynamic results in barbarous wind that howl across the aerofoil at thousands of miles per time of day . Yes , 1000 .
By using Jupiter as a guide for the model , Lewis and her confrere imagined what would happen to it if its surface temperature was dramatically increased and the rate of its gyration greatly diminish . The result , say the researchers , were supersized conditions pattern — including a Great Red Spot that was a quarter of the sizing of the satellite .
Interestingly , regular clouds of water and methane ca n’t mold in such hot environs , pass the researchers to speculate that red-hot Jupiters have cloud made of silicate — fundamentally swarm of rock and dust .
