Exoplanet phase curves from TESS: Results from the Primary Mission and future prospects
Bibliographic record
Abstract
The continuous, long-baseline photometry provided by TESS has enabled detailed phase curve studies of planetary systems. Over the course of the two-year Primary Mission, we carried out a systematic light curve analysis of both known targets and newly discovered systems. By measuring the phase curve, we probed fundamental physical quantities, such as the planet’s dayside temperature, Bond albedo, and day-night heat recirculation efficiency, as well as the host star’s response to the mutual star-planet gravitational interaction. In this talk, I provide an overview of the main results from the Primary Mission. We detected phase curves for over 20 targets and combined TESS-band eclipse measurements with Spitzer secondary eclipse depths to obtain self-consistent dayside brightness temperatures and optical geometric albedos. These albedo measurements have revealed an intriguing apparent trend between increasing dayside temperature and increasing geometric albedo for hot Jupiters. With TESS now well into its Extended Mission, we consider possible avenues for follow-up intensive atmospheric characterization and discuss fruitful opportunities for future study as the telescope revisits these systems in the coming years.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
