- sorae – Discovered 6 planets that resonate with “HD 110067” Important “fossils” in planetary science
This was introduced by sorae in an article on December 10, 2023.Diagram showing that the planets of the star “HD 110067” are in an orbital resonance relationship“is. Six planets have been confirmed to orbit HD 110067. It is said that if you connect the positions of the planets at each timing with lines, a geometric pattern like this will appear.
Planets called “Sub-Neptunes” (*discussion on definitions are at the end of the article), which are intermediate in size between Earth and Neptune, have been found around many stars, but The composition and causes are largely unknown. Examining the formation process of such planets provides clues to understanding the formation process of various types of planetary systems, including the solar system.
Through close observation of observational data and additional observations by an international research team led by Rafael Luque of the University of Chicago, we found that the star HD 110067 (TIC 347332255, TOI 1835) has a total of six planets. . These six planets were researched and discovered on the premise that their orbital periods are in an “orbital resonance” relationship expressed as a simple integer ratio, and many planets are in an orbital resonance relationship. is a very rare discovery. Planetary systems in orbital resonance are considered to be “fossils” that reflect the orbits at the time of their formation, and this is an important discovery in investigating the formation process of sub-Neptunes.
