Star in constellation of Virgo
WASP-54 , also known as BD+00 3088 , is a
binary star system about 825 light-years away. The primary, WASP-54A, is a
F-type main-sequence star , accompanied by the
red dwarf WASP-54B on a wide orbit. WASP-54 is depleted in heavy elements, having 55% of the solar abundance of iron.
[4] The age of WASP-54 is slightly older than the Sun's at 6.9+1.0 −1.9 billion years.
[4]
A multiplicity survey in 2017 did detect a
red dwarf stellar companion WASP-54B 5.7″ away from WASP-54A.
[6] The companion was proven to be co-moving in 2020.
[3]
Planetary system
In 2012 a
transiting
hot Jupiter planet
b was detected on a tight, mildly eccentric
[4] orbit around WASP-54A.
[7]
Planetary equilibrium temperature is 1742+49 −69
K .
