Gamma Leonis b
Gamma Leonis b is an exoplanet located 125.5 light-years from the outer planet Leo in the solar system, orbiting the huge star Gamma Leonis (1). Find On November 6, 2009, the planetary companion surrounding the main star Gamma1 Leonis was announced. [1] In addition, the radial velocity change will also suggest two strong signals at 8.5 days and 1340 days. The periodicity of the former is likely to be caused by the pulsation of the star, while the latter may indicate the presence of an additional planetary companion with a Jupiter mass of 2.14 and a moderate eccentricity (e = 0.13) located at 2.6 AU from the giant star position. Nevertheless, the nature of this signal is still unclear, and further research is needed to confirm or exclude additional interstellar companions.
CHARACTERISTICS:
The planet has a minimum mass of 8.78 Jupiter masses. The true mass, as with the majority of other extrasolar planets discovered by the radial velocity method, is unknown.
