J/A+A/359/18  Line-strength predictions in Elliptical Galaxies   (Molla+, 2000)

Models for the interpretation of Ca Triplet and the blue spectral indices in elliptical nuclei. Molla M., Garcia-Vargas M.L. <Astron. Astrophys. 359, 18 (2000)> =2000A&A...359...18M
ADC_Keywords: Models, evolutionary ; Equivalent widths Keywords: galaxies: elliptical and lenticular, cD Description: This table shows the line-strength predictions computed for: CaT, NaI, and MgI in the near infrared and Mgb, Mg2, Fe52, Fe53, NaD and Hβ, in the blue-visible range, for Single Stellar Population (SSP) of 6 different metallicities, (Z=0.0004, 0.001, 0.004, 0.008, 0.02 and 0.05), and ages from log(age)=6.60 (4Gyr) to log(age)=10.30 (20Gyr), in steps of 0.10dex from 6.60 until 10.00, and 0.02 afterwards. (Therefore there are 50 records for each metallicity except that Z=0.001 has only 47). All indices have been computed taken the model atmospheres from Lejeune et al. (1997, Cat. J/A+AS/125/229, 1998, Cat. J/A+AS/130/65) and Clegg & Middlemass (1987MNRAS.228..759C) for hot stars (Teff > 50000 K). The used isochrones are from the Padova group (Bressan et al., 1993, Cat. J/A+AS/100/647). The total mass of every SSP is 109M with a Salpeter-type IMF, Phi(m)=m, with α=2.35, from mlow=0.6M☉_ to mup=100M. The fitting functions for blue indices are those from Worthey et al. (1994, Cat. J/ApJS/94/687). File Summary:
