- BD-07 436, also known as WASP-77 since 2012, is a binary star system about 344 light-years away. The star's components appears to have a different age, with the secondary older than 9 billion years, while the primary's age is 5 billion years. The BD-07 436 system's concentration of heavy elements is similar to the Sun. Its stars display moderate chromospheric activity, including x-ray flares. The primary is a G-type main-sequence star, BD-07 436A (WASP-77A). The star is rotating rapidly, being spun up by the tides raised by the giant planet on its close orbit. The secondary is a K-type main-sequence star BD-07 436B orbiting at a distance of 461+200−140 AU. (en)
- WASP-77A — широкая двойная звезда в созвездии Кита на расстоянии приблизительно 355 световых лет (около 109 парсек) от нас. Вокруг звезды обращается, как минимум, одна планета. (ru)
