HD 95338 b Archives - Astrobiology

Sensitivity maps for the four CHEOPS visits of HD 95338. The first row represents the best-fit box depth (i.e. moon radius) in the ∆T0–W space. The 3σ lower limit of the moon radius is shown in the second row, while the third and fourth rows represent the ∆BIC and ∆AIC values between a solution with and without a moon. The empty (blank) areas are values that are below a threshold of 0 R⊕ for the moon radius (first 2 rows) and a threshold of 2 for the ∆BIC and ∆AIC (last 2 rows). The grey squares (and corresponding dotted lines) show the position of the transit of HD 95338b in this parameter space for each visit. An underlying linear trend is assumed for each of the four visits. -- astro-ph.EP

The CHEOPS View Of HD 95338b: Refined Transit Parameters, And A Search For Exomoons

Despite the ever-increasing number of known exoplanets, no uncontested detections have been made of their satellites, known as exomoons.
