Researchers may have detected the hydroxonium ion (H3O+) in space and Halley's Comet. If confirmed, this ion is abundant in interstellar gas, aligning with theoretical models.

Area of Science:

  • Astrochemistry
  • Molecular Spectroscopy

Background:

  • The hydroxonium ion (H3O+) is a crucial species in interstellar ion-molecule chemistry.
  • Previous attempts to detect H3O+ in the interstellar medium (ISM) and comets have been inconclusive.

Purpose of the Study:

  • To search for and potentially identify the P(2,1) line of H3O+ in astronomical sources.
  • To determine the abundance and production rate of H3O+ if the identification is confirmed.

Main Methods:

  • Observational astronomy targeting specific spectral lines.
  • Analysis of spectral data from OMC1 and SgrB2, and Halley's Comet.

Main Results:

  • A spectral line possibly attributable to H3O+ was detected in OMC1 and SgrB2.

  • Assuming the detection is H3O+, its fractional abundance in OMC1 and SgrB2 is estimated at ~10^-9.
  • The estimated production rate in Halley's Comet is ~10^28 s^-1.

    • Conclusions:

    • The potential detection of H3O+ in OMC1 and SgrB2 requires further verification through observation of other lines or isotopic variants.
    • If confirmed, H3O+ would be a significantly abundant molecular ion in the ISM, consistent with theoretical predictions.
