The spectrum of HD 160762 (iota Her)
PLOTS:
p3780-4210 R=6500
p4245-4311 R=31000
p6533-6583 R=96000 - echelle
p6546-6617 R=60000 - 1200tr/mm
The spectra were observed in year 1992 by Bonifacio at OHP with the 1.52 m
telescope equipped with the AURELIE spectrograph.
Parameters Teff=17100K, logg=3.80; vturb=0.0 km/s, vsini=6.0 km/s
are from Bonifacio et al., 1995, A&AS 110, 441
The model is an ATLAS9-ODFNEW model atmosphere.
No solar abundances: N -4.19 [-0.20]
Si -4.69 [-0.20]
