Modeling the Seasonality of Wind-Driven Hydrocarbon Waves in Titan’s Polar Lakes
Titan, the only body in the solar system aside from Earth with standing liquids on its surface, has high-latitude hydrocarbon lakes and seas. As Titan’s atmosphere generates light winds, there […]
![Final best fit for VHS 1256 b. Top panel: same as Fig. 8, but using the two-column approach. Best fit parameters are Teff = 1153 K, log g = 4.0 dex, [M/H] = 0.08 dex, C/O = 0.60, R = 1.2 RJup, with an α = 0.62 so a linear combination of fsed = 0.7 (62%) in grey dashed and fsed = 2.4 (38%) in grey solid line. Both grey fsed components have been scaled by their proportion and multiplied by a factor of 0.6 for visibility. The two fsed component spectra are shown with reduced resolution for visibility. Bottom panel: same as Fig. 8. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/06/Next-generation.png?resize=1200%2C719&ssl=1)
