MASCARA-1b is a confirmed superjovian exoplanet, orbiting the A-type star MASCARA-1 (HD 201585).
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+0.066−0.068 and dayside temperature of 3062+66−68 K.[1] Attempts to spectroscopically characterize its composition were failing as in 2022 due to relatively high planetary surface gravity resulting in compact atmosphere.
