We performed elemental abundances analyses of the mercury-manganese (HgMn) stars 53 Tau, $\beta$ Tau, and $\gamma$ Crv consistent with previous studies of similar stars in this series. The derived $v \sin i$ values for the last two stars are 59 and 32 km s-1, respectively, both of which are greater than those of HgMn stars previously studied. For 53 Tau this analysis using selected wavelength regions replaces one performed with coadded photographic spectra. A stricter upper limit is placed on any Hg II $\lambda$3984 line. The abundances of $\beta$ Tau are usually greater than those of $\gamma$ Crv. But the later star has a Hg II $\lambda$3984 line which the former lacks. Our analysis of $\upsilon$ Her, which was performed with spectrograms obtained with CCD detectors, is extended by using additional spectrograms to increase the range of wavelengths covered longward of $\lambda$4800. Minor changes in the derived abundances result.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
