Description:
Searches for H2O(+) toward HD 187982, Zeta Oph, O micron Per, and Zeta Per have yielded significant upper limits for H2O(+) when compared with existing models for similar lines of sight. Using available oscillator strength data, the column density for HD 187982, for example, cannot exceed 3 x 10 to the 12th per sq cm H2O(+) molecules. The most sensitive measurement for H2O(+) toward Zeta Oph is apparently limited by a blend with upper atmospheric H2O(+), which is also present in the HD 187982 spectrum.
