No, you cannot assume that. Remember the outer layers are made largely of
ionised gas and the extinction distance might be a lot larger than you expect.
we see an averaged effect anyway.

Naturally you would like that to be true.

No doubt some star DO go 'huff-puff' and change temperature as they do. I have
never argued otherwise,..... even though there is no decent theory linking
expansion with temperature change.
However I would say that a majority of co-called cepheids are nothing but
orbiting stars.

The difference between a preacher and a used car salesman is that the latter at least has a product to sell.
