No TiO detected in the hot Neptune-desert planet LTT-9779 b in reflected light at high spectral resolution
The episode discusses a paper finding no titanium dioxide (TiO) in reflected light from LTT-9779 b, a hot Neptune-desert planet. Hosts explore how this non-detection forces consideration of either chemical model limitations or physical obscuration by clouds. They highlight the use of High Resolution Cross-Correlation Spectroscopy (HRCCS) to constrain cloud altitude and data reduction techniques to ensure result quality.
