![Individual CHEOPS transit observations of V1298 Tau c, d, and b displayed in the left, middle, and right panels, respectively. For each planet, the top row presents the raw (pre-detrended) light curves, the middle row shows the corresponding detrended light curves, and the bottom row shows the residuals from the best-fit model. Unbinned data are shown in sky blue, binned data in dark blue, and the best-fit transit model in magenta. The solid brown lines indicate 50 random samples from the MCMC posterior distribution of the combined transit and systematics model.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/CHEOPS.png?resize=1200%2C716&ssl=1)

First Comparative Exoplanetology Within a Transiting Multi-planet System: Comparing the atmospheres of V1298 Tau b and c
The V1298 Tau system (20-30Myr), is a benchmark young multi-planet system that provides the opportunity to perform comparative exoplanetology between planets orbiting the same star right after their formation.
