A search for the cause of cyclical wind variability in O stars
... variability originates close to the stellar surface. The phase−velocity relation shows a maximum at −1400 km s−1 . The general trend of these observations can be well explained by the corotating interaction region (CIR) model. In this model the wind is perturbed by one or more fixed patches on the s ...

The NMR spectrum of nearly-equivalent spin pairs displays a single peak since the spin-spin coupling suppresses the effect of the small chemical shift difference. This situation is found at high magnetic fields when the chemical shifts of two ...

... The effects we are interested in are linear. Linear means that if we have two separate stimuli and two separate responses then the response to the sum of the two stimuli will be the sum of the separate responses. The important implication is that we can then break any arbitrary light wave into a ...
