J/A+A/434/235       Abundances of BHB stars in NGC 1904        (Fabbian+, 2005)

Abundance anomalies in hot horizontal branch stars of the Galactic globular cluster NGC 1904. Fabbian D., Recio-Blanco A., Gratton R.G., Piotto G. <Astron. Astrophys. 434, 235 (2005)> =2005A&A...434..235F
ADC_Keywords: Clusters, globular ; Equivalent widths Keywords: globular clusters: general - globular clusters: individual: M79 - stars: horizontal-branch - stars: abundances Description: The abundance measurements are based on high-resolution optical spectroscopical data, obtained during 2 observing runs with the Ultraviolet and Visual Echelle Spectrograph mounted on Kueyen (Very Large Telescope UT2). Ten target stars in the extended blue horizontal branch of the Galactic globular cluster NGC 1904 (M79) have been analysed. File Summary:
