2024年10月24日 · WASP-33 b is a gas giant exoplanet that orbits a A-type star. Its mass is 2.093 Jupiters, it takes 1.2 days to complete one orbit of its star, and is 0.0239 AU from its star. Its discovery was announced in 2010.

WASP-33b is an extrasolar planet orbiting the star HD 15082. It was the first planet discovered to orbit a Delta Scuti variable star. With a semimajor axis of 0.026 AU (3.9 million km; 2.4 million mi) and a mass likely greater than Jupiter's, [1] it belongs to the hot Jupiter class of planets.

A hot Jupiter type extrasolar planet, named WASP-33b or HD 15082b, orbits this star with an orbital period of 1.22 days. It is the first Delta Scuti variable known to host a planet. [12] HD 15082 is an Am star, which makes its stellar classification challenging to discern.

WASP-33 forms a triple system with an M dwarf and a G dwarf companion star located 238 and 5955 AUs away respectively.

The planetary system WASP-33 hosts at least one planet. This list shows all planetary and stellar components in the system. It gives a quick overview of the hierarchical architecture. This table lists all planets in the system WASP-33. This planet was discovered by Collier Cameron et al. 2010. This was a ground based discovery.

This page summarises the information held within TEPCat for the transiting planetary system WASP-33. Please see here for descriptions of the quantities given below.

WASP-33b is the hottest of the WASP planets, being the only one so far found orbiting a very hot A-type star. A team led by Korey Haynes from NASA’s Goddard Space Flight Center, have used Hubble to show that WASP-33b has a “stratosphere”.

2020年7月3日 · We present the detection and characterization of the full-orbit phase curve and secondary eclipse of the ultra-hot Jupiter WASP-33b at optical wavelengths, along with the pulsation spectrum of the host star. We analyzed data collected by the Transiting Exoplanet Survey Satellite (TESS) in sector 18.
