Identification labels:
Interval: 520.2-520.3 nm---->label: 256 26.00 34328 397
256: last 3 digits of wavelengths in nm lambda=520.2256 nm
26.00 = Fe I 26=atomic number of the element (Fe), 00=charge (I)
34328=lower enrgy level in cm-1
397=per mil residual intensity of isolated line before broadening (rotational + instrumental)
RED LABELS: identifications in the primary
BLACK LABELS: identifications in the secondary
Herbig F5 IVe star- Spectroscopic binary. A and B are the primary and the secondary stars. Teff=6500 K from Alencar et al. (2003)
A: Star parameters: Teff=6500 K, log g=4.5, vturb=1 km/sec (from spectrum)
vsini=18 km/sec from several lines in the spectrum.
B: Star parameters: Teff=6500 K, log g=4.5, vturb=2 km/sec (from spectrum)
vsini=21 km/sec from several lines in the spectrum.
The two components are surrounded by a circumbinary disk which may
obscure the liminosity of the secondary. We adopted as luminosty reduction
for the B star these percetages from Li 6707 and Sr II 4077 and 4215.
