After the Vogt group published their report on the fifth and sixth planets, some other astronomers published opposing results. In 2012, these other scientists said that planets 581f and 581g did not actually exist. Their report stated that the Vogt group's new findings were false positives. They looked at the original Doppler spectroscopy data again, and found no signs of the two new planets.
