Does someone know the mass of the mother star WASP-18b is circling around as well as the rotation speed?

Janus said:Given the period of WASP-18b, and its distance (~.02 AU), I come up with a mass for the star of 1.2 solar masses, which agrees with the articles which say that it is a sun-like star.
WASP-18b is an exoplanet (a planet outside of our solar system) that was discovered in 2009. It is considered a mystery because of its unusual characteristics, such as its proximity to its parent star and its extremely hot temperature.
The mass and rotation of the mother star of WASP-18b was determined through a technique called radial velocity, which measures the slight changes in the star's light wavelength caused by the gravitational pull of the orbiting planet. This data can then be used to calculate the mass and rotation of the star.
Understanding the mass and rotation of the mother star is important because it provides valuable information about the formation and evolution of both the star and the planet. It can also help scientists determine the planet's orbital characteristics and potential habitability.
The extreme temperature of WASP-18b, which is estimated to be around 2,700 degrees Celsius, causes its atmosphere to expand and escape into space. This results in the planet having a very thin and tenuous atmosphere compared to other exoplanets.
Some potential future studies that could further our understanding of WASP-18b include using the James Webb Space Telescope to study the planet's atmosphere in more detail, and using simulations and models to better understand its formation and evolution. Additionally, continued observations and data collection of the planet and its parent star can help further our understanding of this mysterious exoplanet.
