HD 43197

HD 43197 is a yellow dwarf star located approximately 183 light-years away in the constellation Pictor. It is of spectral type G3V, similar to our Sun but slightly cooler and less massive. The star is also known by the designation HIP 29525.

HD 43197 is of particular interest to astronomers due to the discovery of a directly imaged exoplanet, HD 43197 b, orbiting the star. The planet is a gas giant, significantly more massive than Jupiter, and has a wide orbit around its host star. The discovery and subsequent study of HD 43197 b provide valuable insights into the formation and evolution of planetary systems, particularly the formation of gas giants at large orbital distances. The planet's relatively wide separation from its star allows for detailed observations and characterization of its atmosphere.

The star's relatively quiet nature and well-defined properties make it a valuable benchmark for understanding stellar activity and its influence on exoplanetary systems. Further studies of HD 43197 and its planet are ongoing, aimed at refining our understanding of its orbital parameters, atmospheric composition, and the overall dynamics of the system.
