This study analyzes the characteristics of LaO bands in the spectra of cool S-type stars and calculates spectroscopic constants and radiative lifetimes for the A(2)pi state. A line list for the LaO bands is provided, which can be used to determine the abundance of LaO in stars.
LaO bands are found in the spectra of cool S-type stars. The bands of the A(2)pi-X-2 sigma(+) transition with v''<= 3 v'<= 4 are rotationally analyzed, providing spectroscopic constants for the A(2)pi state. Line strengths are calculated using an ab initio transition dipole moment function, and radiative lifetimes for the A(2)pi state have also been computed. A line list for the A(2)pi-X-2 sigma(+) transition of LaO is provided and can be used to determine LaO stellar abundances.
