HD 143699 is a yellow dwarf star located approximately 168 light-years away in the constellation Corona Australis. It is a main-sequence star, meaning it is fusing hydrogen into helium in its core, like our Sun.
Stellar Properties:
HD 143699 is a G0V star, indicating a spectral type of G0 and a luminosity class of V (main sequence). It has a mass and radius slightly larger than the Sun. Its surface temperature is also a bit higher than the Sun's, resulting in its yellowish color.
Planetary System:
HD 143699 is known to host at least one confirmed exoplanet, designated HD 143699 b. This exoplanet is a hot Jupiter, meaning it is a gas giant with a mass comparable to Jupiter but orbits extremely close to its host star, resulting in a very short orbital period.
Discovery and Observation:
The exoplanet HD 143699 b was discovered through the radial velocity method, which detects variations in a star's velocity caused by the gravitational pull of an orbiting planet. Observations were conducted using ground-based telescopes. Further observations and studies of the star and its planet are ongoing to better understand their properties and the formation of planetary systems.
