That's becasuse it has a large cool star very close by. We cannot resolve the orbit. All we can detect is the brightness variation and the (its) daily temperature fluctuation due to the day/night effect.

So please tell me why they're not using a reference signal in the LHC of about 1.3787 MHz again? http://groups-beta.google.com/group/sci.physics.relativity/msg/d19ec5acd47fbe44?dmode=source [.sigsnip] -- #191, ewill3(a)earthlink.net It's still legal to go .sigless.

You don't only have to be a crackpot, you have to be an extremely ignorant and stupid crackpot to claim that Cepheids are something else than what the observations tell them to be, namely pulsating stars. Here is a small part of what we know about Delta Cephei: It is a super giant. Distance 273 parsec (890 ly) Its mean radius is 41.6 solar radii or 0.193 AU Its mass ca. 5 solar masses Its absolute magnitude varies between -4.34 and -3.47 with period 5.366270 days = 0.0147 year Its spectral class and temperature varies between F5 - 6800K and G2 - 5500K. You claim it orbits a "large cool star". What can a "large cool star" be? A red giant? Let us assume that this companion has a mass of 5 solar masses, the same as Delta Cep. For a binary, we have: Ma + Mb = a^3/P^2 Where Ma and Mb are the stellar masses in solar masses, a is the distance between the star's centres in AU P is the period in years. Inserting the values above gives us: a = 0.129 AU. The centre of the "large cool star" has to be inside of Delta Cep! Don't think you can save it by assuming another mass of your "large cool star". If the radius of this star were zero, and it was skimming the surface of Delta Cep, its mass would have to be 28 solar masses! Its crazy. > You can learn a lot by discussing things with me, Ghost. Quite. He can learn that there is no limit to your stupidity. Paul

That's obviously utter nonsense. Care to try again? My question was: Are you claiming that there are binaries which "puff and blow and turn themselves inside out at exactly their orbit periods" ? :-) I never heard of those binaries. Can you name examples, please? Paul
