J/AJ/107/2184       FK giants and supergiants photometry (Eggen 1994)

Photometry of F-K type bright giants and supergiants. III. The luminosity, reddening, and heavy element abundance of GK stars. Eggen O.J. <Astron. J. 107, 2184 (1994)> =1994AJ....107.2184E (SIMBAD/NED BibCode)
ADC_Keywords: Stars, giant ; Stars, supergiant ; Photometry ; Abundances, [Fe/H] ; Reddening ; Radial velocities Abstract: The reddening, luminosity, and heavy element abundance of 250 bright giants and supergiants of type GK are discussed on the basis of 4 color, DDO, RI, and Geneva photometry. Bright giants of type GK with age greater than 5x108yr, and of type G0/3 with age greater than 2x108yr, are very scarce in the solar neighborhood. The median space motion vectors of the bright giants and supergiants with well determined space motions are (U, V, W)=(+10.6, -13.2, -7.7)±(12.3, 8.8, 8.8)km/s. The M_1 index for 4 color photometry, when corrected for luminosity (gravity) effects, is sensitive to heavy element abundance in the F type stars but not in those of GK type. The CN index reflects the heavy element abundance of the GK stars but may not be reliable for those of type G0/3. The available spectroscopic determinations of [Fe/H] give mixed results with the two largest samples (McWilliam, 1990ApJS...74.1075M; Brown et al, 1989ApJS...71..293B) being internally consistent but with a large zero-point difference. There is a similar zero-point shift in the peak frequency of the photometrically determined values of P[Fe/H] for the F type and for the GK type stars. There is little evidence for an appreciable galactic, radial gradient in the P[Fe/H] values. A previously noted correlation of the heavy element abundance index, {DELTA}M1, with the amplitude defect in the B light curves of Cepheids, FB, and interpretation of the (PLFB) relation as a (PL[Fe/H]) relation needs further investigation in light of the apparent sensitivity of M1 to Fe/H for the F stars (the domain of the Cepheids with P<10d) and lack of this sensitivity for the G0/3 star (domain of the Cepheids with P>10d).
