Type Shell Stars the Following Table Lists Many of the Hotter Stars

APPENDIX WILLIAM P. BID ELMAN Warner and Swasey Observatory, Case Western Reserve University, Qeveland, Ohio, U.S.A. A List of Early·Type Shell Stars The following table lists many of the hotter stars whose spectra have occasionally or continuously exhibited moderately conspicuous shell phenomena. It includes such well-known objects as P Cygni, 'Y Cassiopeiae, {3 Lyrae and R Monocerotis as well as a host of other less-studied and less-well-understood objects. Novae, classical T Tauri, VV Cephei and symbiotic stars, and stars situated outside the Galaxy have been excluded. The list is undoubtedly very incomplete: many weak or uncertain cases have been left out. It should be remembered that shell phenomena are notoriously variable in time and, in the binaries, often periodically so; thus inclusion in the list does not guarantee that an entry will exhibit shell structure at any specific time. An attempt has been made to distinguish between the objects whenever possible: category (1) includes Of stars and 0, B, and A supergiants showing P Cygni profiles; (2) includes presumably single rapidly rotating stars of classes 0, B, A and F; (3) contains stars deemed to be binary, though the shell phenomena may not always be related to this fact; and (4) is devoted to the early-type nebular objects. In many cases assignment to a particular group is very uncertain or impossible, and in the absence of fairly definite evidence to the contrary stars have generally been assigned to category (2). Many of the brighter Be stars have been found to have variable radial velocity, but they have not been considered to be binaries unless a period has been deter mined. A single reference, not always the most recent, has been given for each entry. The reader is strongly urged to consult the various bibliographies of emission-line objects for additional important data. Magnitudes are visual unless underlined; some useful information has been omitted for lack of space. 'K' numbers refer to the suspected variable catalogues, 'Carlson' to his 1968 Northwestern U. Dissertation. A few references are given to unpublished data from several other investigators. The writer is happy to acknowledge that this work, while largely completed in Cleveland, was put into final form while he was serving as Visiting Professor in the Department of Geophysics and Astronomy of the University of British Columbia in January 1976.
