There is a category named 'flare stars'. These are observed to emit a bright flash periodically. Many emit a double flash.

This is the principle: Photons that are emitted during the 'concave' section of an orbit tend to bunch together as they travel through space. Thus all the information occuring in half an orbit period will arrive at an observer over a much shorter time span. For instance, if a binary pair is itself in a larger orbit around a third object, all the information from the larger half orbit can be compressed into a much shorter time. Thus the binary period might appear to be much storter than it actually is. >> >> If the curve is known, I can tell you fairly accurately the Ecc, yaw and >> the ratio of distance/radial velocity. > >That might work, provided your predictions are verified as correct by >independent data. > >Simply saying the ecc, yaw, etc., are ..... is not enough. > >Much better, however, to be able to go the other way. I wouldn't agree. The BaT is a much better indicator of yaw angle than current methods.

I don't see a reason to invoke a second star. All stars are in some kind of orbit around another star or larger body. My suggestion is that one hot and one cool star in a more eccentric orbit around each other would both experience large tidal effects when they were close.

Paul, I know from their light curves that the eccentricity of their orbits is between about 2 and 4. Do you not agree that tidal effects would be enormous when two heavy stars moved very close to each other at the perihelion. Maybe they would only be a few diameters away from each other. What strange shapes might a ball of gas take on? You can scream and rave as much as you like but at least this mechanism would explain the dead constant period.

Huffing and puffing certainly cannot. Quite.

I have several different versions I have downloaded from the website at different times, in addition to the code you sent me. NONE have a time compression button.

You had your yaw angles off by a large factor due to inverting the brightness data. Even after correcting that, I predict that your guesses at yaw angles will be no better than chance predictions of yaw angles. Only your very strong faith could have mistaken any yaw angles you derived, with inverted brightness curves, for correct information. The fact that you were taking slow rise, rapid fall curves for confirmation of rapid rise, slow fall data should cause you to stop, throw out everything you have been thinking about BaT, and start over again. It didn't. That shows that faith is governing your thinking, not scientific thought. >>>>Of course you are free to say what you like.

You are handwaving in order to hold onto your faith. You have been attempting to support your theory that all cepheid variables are due to binary star systems or single stars with eccentric orbits. > My suggestion is that one hot and one cool star in a more eccentric > orbit around each other would both experience large tidal effects when > they were close.

They show dual doppler shifts. As one star receeds, its light is redshifted. Meanwhile the other star approaches and its light is blue shifted. This is clear, even when the stars can not be visually separated. >>>>It is NOT MY wenbsite, stupid or othewise. >>>>Your velocity/time curve looks like a sine wave.

You said "It definitely does not look like a sine wave when an elliptical orbit is used. It looks just like the typical cepheid one.
