HAT-P-1b
BBOHAT-P-1b Transit
Exoplanet transit observations and related data. Detecting planets around other stars through photometric measurements.
Extra-solar planetary transits (where the planet passes across the star in our line of sight) involve taking photometry data for several hours during the transit to detect the slight reduction in brightness of the star (increase in magnitude).
