MASCARA-1b

MASCARA-1b is a confirmed superjovian exoplanet, orbiting the A-type star MASCARA-1 (HD 201585).

Characteristics
MASCARA-1b is a hot Jupiter transiting its parent A-type star; its orbit is misaligned with the star's rotation. The planet was found unusually reflective for hot Jupiter with the measured geometric albedo of 0.171$$ and dayside temperature of 3062$$ K. Attempts to spectroscopically characterize its composition were failing as in 2022 due to relatively high planetary surface gravity resulting in compact atmosphere.
