Extrasolar planets have been discovered orbiting nearby solar-like stars. This research detects the periodic dimming that occurs when a close-in giant planet passes in front of its parent star as seen from Earth.

TrES_1b
2006/05/30
The graph above shows the transit light curve of TrES-1b on May 30/31, 2006. Observations were made with a 0.35m f/6.3 telescope and a SBIG ST-7e CCD Camera, using a RED filter. Sky conditions were clear with west winds at 10mph, 10% humidity, and a new moon. The blue dots represent 3-point, non-overlapping averages of 500 guided, 60 second exposures. The error bars indicate the standard deviation for each 3-point average. Ingress was predicted at 22:43 PM and egress was predicted at 01:19 AM MDT.
2006/06/11
The graph above shows the transit light curve of TrES-1b on June 11/12, 2006. Observations were made with a 0.35m f/6.3 telescope and a SBIG ST-7e CCD Camera, using a RED filter. Sky conditions were clear, no wind, 9% humidity, and a full moon. The blue dots represent 3-point, non-overlapping averages of 500 guided, 53 second exposures. The error bars indicate the standard deviation for each 3-point average. Ingress was predicted at 01:36 AM and egress was predicted at 04:12 AM MDT.

GREEN Filter
GREEN Filter
The graph above shows the transit light curve of XO-1b on May 31/June 1, 2006. Observations were made with a 0.35m f/6.3 telescope and a SBIG ST-7e CCD Camera, using a GREEN filter. Sky conditions were clear, winds SW at 5mph, 4% humidity, and a new moon. To preserve timing, observations using the RED/GREEN filters were alternated (see RED below).The blue dots represent 3-point, non-overlapping averages of 200 guided, 120 second exposures. The error bars indicate the standard deviation for each 3-point average. Ingress was predicted at 22:21 PM and egress was predicted at 00:07 PM MDT.
