Here's why:
* Surface Temperature: F-type stars have surface temperatures ranging from approximately 6,000 to 7,600 Kelvin. While this is slightly lower than your stated 9,000 K, it's within a range where slight variations can occur.
* Luminosity: F-type stars are typically 1 to 5 times more luminous than our Sun. This aligns well with your specified range of 1 to 20 times the Sun's luminosity.
Note:
* There might be other types of stars that could fit this description, but F-type main sequence stars are the most likely candidates given the provided parameters.
* Stellar properties can vary widely within a spectral class, so the exact temperature and luminosity can change from star to star.
To determine the specific star, you would need more information like its distance, apparent magnitude, and perhaps even its spectral type (e.g., F0, F5, etc.)
