HAT-P-65

HAT-P-65 is a faint star located in the equatorial constellation Equuleus. With an apparent magnitude of 13.16, it requires a telescope to be seen. The star is located away from Earth, but is drifting close with a radial velocity of -48 km/s.

Properties

HAT-P-65 has a similar spectral type to that of the Sun. However, it is 21% more massive, and 86% larger than the latter. HAT-P-65 is slightly hotter, with an effective temperature of 5,916 K compared to 5,778 K of the Sun. It also has a higher luminosity and metallicity, with an iron content 26% greater than the Sun.

Planetary system

In 2016, an inflated hot Jupiter was discovered orbiting the star in a tight 2 day orbit. No significant transit timing variations or evidence of orbital decay was found in a 2024 study by Kang et. al.
