J/A+A/401/997       Wilson-Bappu relation in late-type stars       (Pace+, 2003)

The Wilson-Bappu effect: A tool to determine stellar distances. Pace G., Pasquini L., Ortolani S. <Astron. Astrophys. 401, 997 (2003)> =2003A&A...401..997P
ADC_Keywords: Stars, late-type ; Equivalent widths ; Rotational velocities Keywords: stars: distances - stars: late-type - line: profiles Abstract: Wilson & Bappu (1957ApJ...125..661W) have shown the existence of a remarkable correlation between the width of the emission in the core of the K line of CaII 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 ratio CCD spectra and absolute visual magnitudes from the Hipparcos database. File Summary:

Note (1): The full sample consists of 152 stars, 33 of which have not been used in the present study, because of their high measurement error in the parallax (e_plx/plx>0.1) or because they are multiple systems. We have flagged their HD identificators with an asterisk. Note (2): For the Sun we used the value given by Hayes (1985, IAU Symp., 111, 347). Note (3): Spectral type from Cayrel de Strobel Catalogue (III/200). When the spectral type is not available from this catalogue the data is taken from the Hipparcos database, and is flagged with a asterisk.
