III/260             General Catalogue of Ap and Am stars   (Renson+ 2009)

General catalogue of Ap, HgMn and Am stars. Renson P., Manfroid J. <Astron. Astrophys. in prep. (2009)> =2009A&A...498..961R
ADC_Keywords: Stars, A-type ; Stars, Am ; Stars, Ap Description: A catalogue of 8205 known or suspected Ap, HgMn and Am stars is presented. This is a major update of the catalogue of Ap and Am stars (Renson et al., 1991, III/162). It includes revised identifications, additional stars and revised information. Bertaud and GC identifications were suppressed. HIP and TYC identifications were added. The GC number can be found in notes N for stars without HIP number and for double stars when the components have different numbers (the GC of the other component is then given in note D).

Note (1): Indication of the probability that the star belongs to the considered category: '/' = denotes a star improperly considered Ap or Am '?' = doubtful nature '*' = well-known Ap or Am star ' ' = other cases Note (2): Running number (initially in tens), closely follows the HD order (extension excluded) or, in the absence of HD number, the 1900 right ascension. The running number has been kept for the stars already present in the first edition. The new stars have been inserted following the same scheme whenever possible. Obviously there are several instances where 9 slots were not sufficient, thus the 1900 RA order is not always strictly obeyed. On the other hand it has been possible to respect the HD order. Note (3): the multiplicity letter identifies the component in the case of double or multiple system where components have not a distinct number, except when the luminosity of the other components is negligible. Note (4): BD=Bonn (I/122 and I/119), CD=Cordoba (I/114), CP= Cape photographic (I/108). The choice is made according to the usual convention as adopted in the HD catalogue Note (5): the conventions for greek letters are: *al=alpha *io=iota *rh=rho *be=beta *ka=kappa *si=sigma *ga=gamma *la=lambda *ta=tau *de=delta *mu=mu *up=upsilon *ep=epsilon *nu=nu *ph=phi *dz=dzeta *xi=xi *kh=chi *et=eta *oi=omicron *ps=psi *th=theta *pi=pi *oe=omega Note (6): for close double stars, this magnitude was corrected from the companion's luminosity. Note (7): for close double stars, the colour index refers to the combined light. Note (8): A dash in column 133 indicates an Am star; this dash separates the spectral type deduced from the K line and the spectral type deduced from the metallic lines; delta Del-type stars are classified as Am, and marked with dD. Another character in column 133 means an Ap or HgMn star. The spectrum is followed by the symbols of the elements with abnormal abundances.

Global Notes: Note (G1): the symbols used in columns 145-155 have the following meaning: * = Note or remark of various nature, e.g., about the spectrum. N = Other designations (see also notes A, D, V) [B10] for number in B. Boss's "Preliminary General Catalogue"; GCRV for number in Wilson's General Cat. of Stellar Radial Velocities III/21; second DM number D = Note concerning multiplicity: designation from ADS (Aitken's catalogue, 1932 {1932QB821.A43......}) or BDS (Burnham's catalogue, 1906 {1906QB821.B972.....}), magnitude and angular distance to the companion(s) A = Note concerning clustering: cluster, group or association to which the star belongs, at least optically; star identification number(s) in the cluster or association; the WEBDA identification is added when available V = Note about variability: variable name; nature of the variability, if known, when it is not of the alpha CVn type. P = Note about the known or proposed period observed for the variations of: * the luminosity and/or colours (l) * the magnetic field (m) * the intensity of spectral lines (s) * the radial velocity computed from peculiar element lines (v) B = Note about binarity: period and eccentricity (e); v.r.v. stands for Variable Radial Velocity H = Note about magnetic field: extreme values as observed, or from a fit of a phase diagram * L longitudinal effective field * M mean field modulus * Q quadratic field R = Note concerning the rotational velocity; value of the projected equatorial velocity (v sin i) S = Remarks concerning Stroemgren's photometry uvbyH-beta C = Note about detection criteria, when not classical spectroscopy. Used abbreviations: UV = ultraviolet spectrophotometry (satellite obs.) Gen. = Geneva 7-colour photometry Mtz. = Maitzen's photometry Str. = Stroemgren photometry
