The Wilson–Bappu Effect: a tool to determine stellar distances
Wilson & Bappu (1957) have shown the existence of a remarkable correlation between the width of the emission in the core of the K line of Ca II and the absolute visual magnitude of late–type stars. Here we present a new calibration of the Wilson–Bappu effect based on a sample of 119 nearby stars. We use, for the first time, width measurements based on high resolution and high signal to noise ra...
متن کاملStellar activity and the Wilson-Bappu relation
The Mg II h and k lines of 78 single stars observed with the International Ultraviolet Explorer (IUE) observatory have been analyzed. Stars of spectral classes F, G, K and M and luminosity classes I–V are represented in the sample. From these data it is shown that theWilson-Bappu relation for theMg II h and k lines is fulfilled over a range of 18 magnitudes, i.e. fromMv = +12 toMv = -6. The sam...
متن کاملThe Wilson-Bappu effect of the MgII k line – dependence on stellar temperature, activity and metallicity
The Wilson-Bappu effect is investigated using accurate absolute magnitudes of 65 stars obtained through early release of data from the Hipparcos satellite together with MgII k line widths determined from high resolution spectra observed with the International Ultraviolet Explorer (IUE) observatory. Stars of spectral classes F, G, K and M and luminosity classes I-V are represented in the sample....
متن کاملWilson loops in four-dimensional quantum gravity.
A Wilson loop is defined, in 4-D pure Einstein gravity, as the trace of the holonomy of the Christoffel connection or of the spin connection, and its invariance under the symmetry transformations of the action is showed (diffeomorphisms and local Lorentz transformations). We then compute the loop perturbatively, both on a flat background and in the presence of an external source; we also allow ...
متن کاملGravitational Wilson Loop in Discrete Quantum Gravity
Results for the gravitational Wilson loop, in particular the area law for large loops in the strong coupling region, and the argument for an effective positive cosmological constant, discussed in a previous paper, are extended to other proposed theories of discrete quantum gravity in the strong coupling limit. We argue that the area law is a generic feature of almost all non-perturbative lattic...
