Erratum: ``FUSE Observations of Atomic Abundances and Molecular Hydrogen in the Leading Arm of the Magellanic Stream'' [Astron. J. 121, 992 (2001)]
Abstract
An error was made in the calculation of Astron. J. 121, 992 (2001). The correct equation should read tform~(RnH)- 1~1×109yr(3)for R~10-17 cm3 s-1 and nH=nHI~3 cm-3. The value of 108 yr quoted in the abstract should now be considered a lower limit. Our conclusion that the H2 that formed in the Small Magellanic Cloud survived tidal stripping is strengthened by this revision, since the in situ formation time derived in equation (3) is an order of magnitude longer than previously estimated and is comparable to the age of the Magellanic Stream.
