J1407
(1SWASP J140747.93-394542.6, 1SWASP J140747, V1400 Centauri)
(star eclipsed by a body with a ring system)
J1407 (or 1SWASP J140747.93-394542.6 or 1SWASP J140747) is
a Sun-like star about 450 light-years away.
It came to attention because an eclipse was observed that suggested a
companion with a ring system, like that of Saturn but much,
much larger (on the order of an AU in diameter, roughly 200 times
the diameter of Saturn's ring system). Light-curve patterns
of darkening suggested a planet's such rings passing in front
of the star.
It was hypothesized that this ring system was that of an extra-solar planet
hosted by the star (which has been called J1407b), but it is also
hypothesized to have been a passing object such
as a free-floating planet, and study continues.
The star was discovered by SuperWASP.
