Eclipsing binaries can in principle provide additional constraints to facilitate asteroseismology of one or more pulsating components. We have identified 94 possible eclipsing binary systems in a sample of over 1800 stars observed in long cadence as part of the Kepler Guest Observer Program to search for γ Doradus and δ Scuti star candidates. We show the results of a procedure to fold the light curve to identify the potential binary period, subtract a fit to the binary light curve, and perform a Fourier analysis on the residuals to search for pulsation frequencies that may arise in one or both of the stellar components. From this sample, we have found a large variety of light curve types; about a dozen stars show frequencies consistent with δ Sct or γ Dor pulsations, or light curve features possibly produced by stellar activity (rotating spots). For several stars, the folded candidate ‘binary’ light curve resembles more closely that of an RR Lyr, Cepheid, or high-amplitude δ Sct star. We show highlights of our results and discuss the potential for asteroseismology of the most interesting objects.
What is the state? The State of Freedom offers an important new take on this classic question by exploring what exactly the state did and how it worked. Patrick Joyce asks us to re-examine the ordinary things of the British state from dusty government files and post offices to well-thumbed primers in ancient Greek and Latin and the classrooms and dormitories of public schools and Oxbridge colleges. This is also a history of the 'who' and the 'where' of the state, of the people who ran the state, the government offices they sat in and the college halls they dined in. Patrick Joyce argues that only by considering these things, people and places can we really understand the nature of the modern state. This is both a pioneering new approach to political history in which social and material factors are centre stage, and a highly original history of modern Britain.
