top: the observed rvs and the best-fit single keplerian curve for 24 boo. the horizontal axis is the orbital phase. the derived stellar jitter is also included in the error bar. red circles and green triangles are data taken with slit- and fiber-mode, respectively. bottom: the rv residuals to the orbital fitting. credit: takarada et al. 2018.using radial velocity method a group of japanese astronomers has found that two evolved stars, namely 24 booties and gamma librae, are orbited by gas giant planets. they discovered that 24 booties hosts one planet, while gamma librae is circled by two alien worlds. the finding is detailed in a paper published april 11 on arxiv.org. thanks to the radial velocity (rv) technique, over 600 exoplanets have ...
