Arcturus a well - understood K giant ? Test of model atmospheres and potential companion detection by near - infrared interferometry
We present near-IR interferometric measurements of the K1.5 giant Arcturus (α Bootis), obtained at the IOTA interferometer with the FLUOR instrument, in four narrow filters with central wavelengths ranging from 2.03μm to 2.39μm. These observations were expected to allow us to quantify the wavelength dependence of the diameter of a typical K giant. They are compared to predictions from both plan...
متن کاملDefending principlism well understood.
After presenting the current version of principlism, in the process repudiating a widespread deductivist misinterpretation, a fundamental metaethical disagreement is developed by outlining the deductivistic critique of principlism. Once the grounds for this critique have been understood, the dispute between casuistry, deductivism and principlism can be restructured, and the model of "applicatio...
متن کاملThe K giant star Arcturus : the hybrid nature of its infrared spectrum ⋆
Aims. We investigate the infrared spectrum of Arcturus to clarify the nature of the cool component of its atmosphere, referred to as the CO-mosphere, and its relationship to the warm molecular envelope or the MOLsphere in cooler M (super)giant stars. Methods. We apply the standard methods of spectral analysis to the CO lines measured from the “Infrared Atlas of the Arcturus Spectrum” by Hinkle,...
متن کاملIndoor Positioning using Wi-Fi – How Well Is the Problem Understood?
The past decade has witnessed substantial research on methods for indoor Wi-Fi positioning. While much effort has gone into achieving high positioning accuracy and easing fingerprint collection, it is our contention that the general problem is not sufficiently well understood, thus preventing deployments and their usage by applications to become more widespread. Based on our own and published e...
متن کاملIs General Relativity 'essentially Understood' ? *
The content of Einstein's theory of gravitation is encoded in the properties of the solutions to his field equations. There has been obtained a wealth of information about these solutions in the ninety years the theory has been around. It led to the prediction and the observation of physical phenomena which confirm the important role of general relativity in physics. The understanding of the do...
