PRELIMINARY WORK: Spectroscopic Binary ADOPTED PARAMETERS: Primary: HgMn star Teff=11000K, logg=3.80; vturb=0.0 km/s, vsini=1.0 km/s, AT12 Adgiustment of parameters from Stromgren photometry (11100,3.8) in order to fit Hbeta and get Fe I.Fe II ionization equilibrium. Secondary: Teff=8750 K (from DV) logg=4.0 (assumed), vsini=200 km/sec (from Mg II, 4481) L(A)=63% L(B)=37% from the ratio of model fluxes. --------------------------------------------- (Dolk et al. 2002, A&A 385,111 used: Primary: Teff=11088K, logg=3.79 from Stromgren photometry as a single star, vturb=0.0 km/s, vsini=2.0 km/s Secondary: Teff=8500 K, logg=4.0, vsini=50 km/sec L(A)/L(B)=4. ) --------------------------------------------- Primary: No solar abundances: He -1.70 [-0.65] C -4.12 [-0.60] N <-5.62 <[-1.50] O -3.70 [-0.49] Mg -5.06 [-0.60] Al -7.17 [-1.60] Si -5.30 [-0.81] P -6.00 [+0.59] S -5.21 [-0.50] Ca -5.83 [-0.15] V -9.44 [-1.40]: Cr -5.80 [+0.57] Mn -5.00 [+1.65] Ni -6.79 [-1.00] Sr -7.07 [+2.00] Y -5.95 [+3.85] Zr -8.20 [+1.24] Xe -6.00 [+3.87] Pr -9.50 [+1.80] Nd -9.14 [+1.40] Yb -8.11 [-2.85] Pt -6.70 [+3.54] isotopic anomaly Au -7.23 [+3.80] Hg -5.70 [+5.25] isotopic anomaly Ca II infrared triplet: Dlam=+0.17, 0.18, 0.18 Pt 194 0% terrest. 32.9% 195 0% 33.8% 196 0% 25.2% 198 100% 7.19% Hg 196 0% terrest. 0.1534% 198 0.16% 9.968 % 199 0.76% 16.873% 200 2.97% 23.096% 201 4.83% 13.181% 202 50.58% 29.863% 204 40.74% 6.865% Secondary: solar abundances
