J/A+A/346/586       Rotating models of A and F stars   (Perez Hernandez+, 1999)

Photometric parameters for rotating models of A- and F-type stars Perez Hernandez F., Claret A., Hernandez M.M., Michel E. <Astron. Astrophys. 346, 586 (1999)> =1999A&A...346..586P (SIMBAD/NED BibCode)
ADC_Keywords: Models, atmosphere ; Stars, A-type ; Stars, F-type ; Photometry, uvby ; Photometry, Geneva ; Photometry, UBV Keywords: stars: rotation - stars: fundamental parameters - stars: delta Sct - open clusters: individual: Praesepe Description: Magnitude differences between rotating and non-rotating copartners for a grid of models with solar metallicity are tabulated here. The results are expressed in terms of the dimensionless angular velocity w-bar- defined in Eq.(1) of the paper, the angle of inclination i and the atmospheric parameters Te and ge defined in Eqs.(22) and (21), respectively. To obtain the absolute magnitudes for a given rotating model, the magnitudes of a non-rotating model with Teff=Te, g=ge and the same intrinsic luminosity must be added. Results are given for the filters in the Geneva, Johnson and Stroemgren systems. Eq (1): w-bar = Ω/Ωc, where Ω is the angular velocity of the star, and Ωc2=8GM/(27R3p), where M is the mass and Rp the polar radius. File Summary:
