Features
COROT-1b is a loose planet with a radius of 1.49 times greater than Jupiter , and a mass of approximately 1.03 times. Its large size is due to the low density and strong heating of its parent star, causing the outer layers of the atmosphere to swell.
The temperature on the surface of the planet is not lower than 1500 ° C, and the period of revolution of the planet around the star is approximately 1.5 days. The distance to the star is 0.025 A. e. , making the planet one of the closest to a star.
The inclination of the COROT-1b orbit is 77 degrees, so the planet rotates almost perpendicular to the equator of the star.
Phase Observation
In May 2009, COROT-1b became the first exoplanet for which the results of optical phase observations were announced [4] . These observations suggest that there is no significant heat transfer between the night and day sides of the planet [5] .
