J/A+A/407/631   Catalogue of stellar effective magnetic fields  (Bychkov+, 2003)

Catalogue of averaged stellar effective magnetic fields. I. Chemically peculiar A and B type stars. Bychkov V.D., Bychkova L.V., Madej J. <Astron. Astrophys. 407, 631 (2003)> =2003A&A...407..631B
ADC_Keywords: Stars, peculiar ; Magnetic fields Keywords: Stars: magnetic fields - Stars: fundamental parameters Abstract: We present the catalogue of averaged quadratic effective magnetic fields <Be> for 596 main sequence and giant stars. The catalogue is derived from measurements of the stellar effective magnetic field strengths Be, which were compiled from the existing literature. Description: Averaged longitudinal magnetic fields <Be> and other data are listed. For each star we present HD number, spectral type, <Be>, rms standard error of <Be>, chi2 for one degree of freedom, method of Be determination, reference number and comments. File Summary:
