HD 3167 Archives

Best-fit white light (5.06–10.55 µm) curves of HD 3167 b’s secondary eclipse from our SPARTA (blue), Eureka! (red), and exoTEDRF (green) reductions. (Top) Binned raw white light fluxes. The best-fit full SPARTA model (with integration-level x decorrelation), Eureka, and exoTEDRF models are shown alongside the quadratic ramp component shown as dashed lines. (Middle) Binned fluxes after dividing by the best-fit systematics model for each reduction. Retrieved eclipse depths and uncertainties are shown on the right. (Bottom) Binned residuals of the best-fit full models. For all plots, Eureka!/exoTEDRF data are offset by 0.001/0.002 days for visual clarity. -- astro-ph.EP

‘Lava worlds’-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characterization. Thermal emission observations show an apparent […]
