51 Eridani b
(51 Eri b)
(Jupiter-like planet discovered in 2015)
51 Eridani b (aka 51 Eri b) is an extra-solar planet discovered
through direct imaging in 2015 with the Gemini Planet Imager.
It orbits about 14 AU from F-type star, 51 Eridani.
As a directly-imaged object, data from observing it is useful in
modeling apparently-similar objects orbiting closer to their hosts.
The effective temperature derived through spectroscopy
is 700 K, a temperature that requires explanation,
given the star's luminosity and distance.
Models of the planet that include clouds suggest a mass
of about 2 Jupiter masses is plausible. The star's age is thought
to be around 20 million years, which suggests a similar age for the
planet, and constrains it to be no more than that.
