Non-LTE LINE FORMATION FOR Zr I/II IN COOL STARS
Non-local thermodynamical equilibrium (non-LTE) line formation for neutral and singly-ionized zirconium is considered for the first time through a range of stellar parameters when the Zr abundance varies from the solar value down to [Zr/H] = - 3. The model atom includes 63 combined energy levels of...
