# TESS Program G09114 Title: A Systematic Search For Temporal Atmospheric Variability On Exoplanets PI: Wong, Ian - Space Telescope Science Institute Type: SMALL Summary: TESS light curves offer a full view of the orbital phase, capturing the transit, secondary eclipse, and sinusoidal phase modulations. The secondary eclipse depth and the shape of the modulations reveal key details about the planet s atmosphere. We propose to extend a systematic search for temporal atmospheric variability of hot Jupiters through Cycle 9, motivated by theoretical predictions and prior observational evidence. Combining Cycle 9 data with earlier cycles will extend the TESS time baseline and provide an additional measurement of targets observed only in 2-4 previous cycles, enabling a deeper investigation of atmospheric changes and improving phase-curve quality. This project maximizes TESS's scientific return by extracting all temporal information encoded in the light curves. # Sector 108 targets observed (2 min: 17, 20 s: 17) 268766053,31.9091,-20.6618,11.76,G09058;G09114;G09031;20SECONDTARGET 1129033,37.1558,-7.0607,9.63,G09194;G09114;20SECONDTARGET 382391899,43.6881,-10.898,11.05,G09058;G09114;20SECONDTARGET 268532343,14.827,-19.7711,10.83,G09058;G09114;20SECONDTARGET 139528693,63.7563,-22.1164,11.83,G09114;20SECONDTARGET 178284730,60.3855,-20.4509,10.31,G09114;G09031;G09180;20SECONDTARGET 178289267,60.9482,-19.0569,11.71,G09058;G09114;20SECONDTARGET 122612091,41.0401,-30.1691,10.46,G09058;G09114;20SECONDTARGET 209459275,46.8185,-31.1632,10.57,G09058;G09114;20SECONDTARGET 170634116,66.3709,-30.6004,9.68,G09058;G09114;20SECONDTARGET 47911178,98.3511,-23.486,9.79,G09058;G09114;20SECONDTARGET 147977348,99.7346,-36.6461,10.04,G09058;G09114;20SECONDTARGET 53458803,102.8474,-29.0587,11.87,G09058;G09114;20SECONDTARGET 97921547,107.8333,-35.8505,11.1,G09058;G09114;20SECONDTARGET 100389539,109.3883,-19.8289,10.9,G09058;G09114;20SECONDTARGET 409594381,110.2495,-13.9263,11.01,G09058;G09114;20SECONDTARGET 415276070,114.9426,-21.4856,11.4,G09058;G09114;20SECONDTARGET # Sector 109 targets observed (2 min: 16, 20 s: 16) 382391899,43.6881,-10.898,11.05,G09058;G09114;20SECONDTARGET 13021029,75.2997,-26.0541,11.72,G09058;G09114;20SECONDTARGET 317483660,88.0929,-13.3725,11.56,G09058;G09114;20SECONDTARGET 43647325,76.082,-6.2297,10.44,G09058;G09114;20SECONDTARGET 139528693,63.7563,-22.1164,11.83,G09114;20SECONDTARGET 178284730,60.3855,-20.4509,10.31,G09114;G09031;G09180;20SECONDTARGET 178289267,60.9482,-19.0569,11.71,G09058;G09114;20SECONDTARGET 47911178,98.3511,-23.486,9.79,G09058;G09114;20SECONDTARGET 147977348,99.7346,-36.6461,10.04,G09058;G09114;20SECONDTARGET 22529346,107.6002,-39.0972,10.06,G09058;G09114;20SECONDTARGET 53458803,102.8474,-29.0587,11.87,G09058;G09114;20SECONDTARGET 97921547,107.8333,-35.8505,11.1,G09058;G09114;20SECONDTARGET 100389539,109.3883,-19.8289,10.9,G09058;G09114;20SECONDTARGET 415276070,114.9426,-21.4856,11.4,G09058;G09114;20SECONDTARGET 151483286,119.0598,-35.1167,11.39,G09058;G09114;20SECONDTARGET 118956453,135.4163,-20.7204,11.94,G09058;G09114;20SECONDTARGET
