The A2Π-X2Σ+ Band System of YO.

BERNATH P.F., BHUSAL M. and PASTOREK A.

Abstract (from CDS):

YO bands are conspicuous in the spectra of S stars. The laboratory spectrum of the A2Π-X2Σ+ electronic transition has been recorded with a Fourier transform spectrometer using a composite-wall hollow cathode lamp source. The A2Π-X2Σ+ transition with ${v}^{{\prime} }\leqslant 4$ and v″ ≤ 4 has been rotationally analyzed using the modern spectral fitting program PGOPHER. Vibronic band strengths were calculated using an ab initio transition dipole moment function. A line list for the A2Π-X2Σ+ transition is provided and can be utilized in the modeling of S stars.
