You know, this Cassini state 2 speculation leads me to the following questions: is it likely that terrestrial planets (as opposed to gas giants) could end up in this configuration, and could a terrestrial planet in this configuration at the right distance from its star support a habitable climate? Thanks for the info.

I'll be writing a detailed post very shortly... On the Cassini state 2 simulations — we’ve got the results, and the paper just came back from review at ApJL.

That's extremely interesting. Do you know which Spitzer bands they used? The Ups And observaton was at 24 microns, where the atmospheric opacity is quite high. At high opacity, you're seeing a low-pressure upper layer in the atmosphere which has a small heat capacity, which could explain the discrepancy if they observed at, say, 8 microns. best, Greg Hi Andy,

Which makes Upsilon Andromedae rather anomalous, no? Any word on how Cassini state 2 looks in the infrared?

That inevitably called up the still vivid image of two women sweltering in a New York apartment (one of them, the actress Lois Nettleton, is pictured above).
