Today I helped Abby Shaum (NYU) finish her poster for the #AAS235 Meeting on using signal processing—and in particular phase demodulation—to find binary companions to stars with coherent asteroseismic modes in the NASA Kepler Mission data. Our abstract ended up being different from what we submitted! I hope no-one minds. But she has a beautiful result, and a pretty mechanistic method to search for binaries. Now our next thing is to figure out how to generalize the method to modes that aren't coherent over the full mission lifetime. If we can do that, there is a lot more we can find, I suspect.
