"The BT2 water line list reveals interesting changes
in the Deep Impact spectrum"
ABSTRACT: On 4th July 2005, observers on Mauna Kea and other sites around the world
monitored the Deep Impact event.
Researchers at UCL have used their recently published BT2 line list to
examine 48 UKIRT spectra of comet Tempel 1 obtained on impact night. In
addition to observing flourescent transitions from lower-lying states they
have identified transitions from higher energy states that have previously
not been recorded in cometary spectra.
The manner in which the intensities of the two types of lines changed
during the two and-a-half hours post impact should lead to a better
understanding of the physical processes involved.
