HD 219077
HD 219077 is a G-class yellow dwarf star.
==Planetary system==
From 1998 to 2012, the star was under observance from "the CORALIE echelle spectrograph at La Silla Observatory".
In 2012, a long-period, wide-orbiting planet was deduced by radial velocity. This was published in November.
The discoverers noted that HD 219077 b is among the "three most eccentric planets with a period larger than 5 years" - along with HD 98649 b and HD 166724 b, also found in CORALIE. The reason for this eccentricity is unknown. They submit HD 219077 b as a "candidate for direct imaging", once it gets out to "11.0 AU at apoastron", and 375 milliarcseconds of separation relative to Earth.〔
