Result From Kepler A Planets Light Blocked By A Star

This morning the invited talk at the AAS tryst was William Bourucki of NASA/Ames language about first fight from the Kepler duty. The coolest thing he described was an object that's too hot to be a planet, but too big to be the tint of star it could be! Spare about that end. Specifically now, I fantasy to show my imprecise snapshot of his record of the lightcurve of an already-known exoplanet named HAT-P-7: This is a record of the glare of the star against time. This was a former acknowledged planet. In the top, you see the Kepler data that fight from in the function of the planet "transits" the star. That is, the planet moves creatively the face of the star, preventive out a a small number of bit of the starlight, causing the star to get merely a wee bit dimmer. The planet is extreme dimmer than the star, so it honest blocks out a bit of the starlight, but Kepler is alert adequate that this is an unfeasibly strong detection. What's cool as a cucumber is in the function of you film in on the record. You see a flicker dip to the conviction. Having the status of you're seeing give to is the light of the "planet" being closed by the star. The planet shows reflected light from the star, which adds to the wonderful light you see. So far, in the function of the planet is "occulted" by the star, you no longer see that reflected light and you get a secondary dip. A matter of extrasolar planets wolf been detected by looking for stars whose light is rapidly closed out due to an orbiting planet stimulating in start of the star. Kepler is a spacecraft made-up to outline lots of these planets. It's absolutely cool as a cucumber that it's alert adequate that it's seeing the light of a planet closed out by a star!
