A ring fpr Haumea Options

[MarcF]

Haumea was already weird with its size, shape, color and moons. Now it has also a ring :-)

"Here we report observations from multiple Earth-based observatories of Haumea passing in front of a distant star (a multi-chord stellar occultation). Secondary events observed around the main body of Haumea are consistent with the presence of a ring with an opacity of 0.5, width of 70 kilometres and radius of about 2,287 kilometres. The ring is coplanar with both Haumea’s equator and the orbit of its satellite Hi’iaka. The radius of the ring places it close to the 3:1 mean-motion resonance with Haumea’s spin period..."

I recall that in Clement's novel, the probe's scientific data is fully recovered by the natives; can't rely on that with Haumea!
Any idea how much surface gravity varies from the equator to the poles?
