III/152           Observed Periods of Ap Stars       (Catalano+ 1984)

Catalog of Observed Periods of Ap Stars Catalano F.A., Renson P. <Astron. Astrophys. Suppl. Ser., 55, 371 (1984)> =1984A&AS...55..371C
ADC_Keywords: Stars, Ap ; Stars, variable Description: A table of all the periods proposed up to 1983 for Ap stars is given with references. The main identifiers (HD, HR, ... numbers), the variable-star name, and the spectral type are listed for each star in the table. The nature of the periodic variability discovered (luminosity, equivalent widths of the lines, magnetic field, ...) is presented in a codified way. Notes are provided, mainly about duplicities.

Note on elem: Principal elements with abnormally intense lines. The abbreviation "He fbl." signifies that the star is "of weak helium", but "He" alone signifies abnormally intense helium lines. Note on u_Per: : in byte 64 = Uncertainty is greater than omitted digits. ? in byte 65 = period value is doubtful because of too few observations or other possible values Note on n_Per: letter in byte indicates period applies to: ------ ---- ------------------------------------------------------------ l 73 variations of luminosity and/or color m 74 variations of "effective" magnetic field analogous to Babcock (1958ApJ...128..228B) s 75 variations in intensity of certain spectral lines v 76 variations in wavelength of certain lines, often interpreted as variations of radial velocities

Note on Per3: Values taken from a single article appear on a single record. Values separated by a slash "/" are equally probable. Less probable values are parenthesized and preceded by a slash "(/)". Values in parentheses not preceded by a slash "()" are different possible values included in the uncertainties, which are given if available in the referenced publication. Units are days, unless otherwise specified.
