Measuring the orbital inclination of Z Andromedae from Rayleigh scattering
Measuring the orbital inclination of Z Andromedae from Rayleigh scattering
Context. The orbital inclination of the symbiotic prototype Z And has not been established yet. At present, two very different values are considered, i ~ 44° and i ≳ 73°. The correct value of i is a key parameter in, for example, modeling the highly-collimated jets of Z And.
