Constraining The Parameters Of Six Known Transiting Exoplanets, Mackenzie Lee Jones

Undergraduate Honors Thesis Collection

We present two new transits of GJ~1214b, five of TrES-lb, two of XO~2b, and one each of TrES~3b)WASP-16b and WASP- 36b. These observations were made with multiple observatories including IRTF-MORIS, Butler University's Holcomb Observatory, SARA-KPNO, and SARA-eTIO. Due to poor conditions and a lack of good comparison stars within the field of view, the parameter values for the radius ratio, inclination, and orbital distance, found for GJ-1214b are not reliable. The timing values, while still suspect, suggest consistency with the current ephemeris. After further analysis, the radius ratio we found for TrES-1b in Sloan r' is 0.0.13501±0.0001l, which differs by …
