The characterization of young planets (< 300 Myr) is pivotal for understanding planet formation and evolution. We present the 3-5μm transmission spectrum of the 17 Myr, Jupiter-size (R ∼10R⊕) planet, […]
![Transmission spectrum of HIP 67522 b with the best (lowest sigma) atmospheric models for each scenario: for the clear atmosphere model, M = 15M⊕, C/O = 0.25, [M/H] = 1.5 (purple); for the cloudy model, M = 8M⊕, C/O = 0.25, [M/H] = 1.5 (pink); for the photochemical model, M = 15M⊕, C/O = 0.50, [M/H] = 1.0 (red). Models are binned to a spectral resolution of R=600 and data points are binned to a bin size of 4. The plot on the right highlights the presence of SO2 in the atmosphere of the planet. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/10/The-Featherweight-Giant.png?resize=1200%2C720&ssl=1)
