Wolf 1061

Wolf 1061 (also known as HIP 80824 and V2306 Ophiuchi) is an M-class red dwarf star located about 14.1 light-years away in the constellation Ophiuchus.

[8] A seven years study found no evidence of photometric transits and confirms the radial velocity signals are not due to stellar activity.

In December 2015, a team of astronomers from the University of New South Wales announced the discovery of three planets orbiting Wolf 1061.

The planets were detected by analyzing 10 years of observations of the Wolf 1061 system by the HARPS spectrograph at La Silla Observatory in Chile.

The team used archive radial velocity measurements of the star's spectrum in the HARPS data and, along with 8 years of photometry from the All Sky Automated Survey, discovered two definite planets with orbital periods of around 4.9 and 17.9 days and a very likely third with a period of 67.3 days.
