... Figure 3 shows several tails resulting from trap 2-637. ... The solid line shows a simple exponential decay, as described in our idealized model. It appears that the behavior of the bright traps has been relatively constant with time, and the simple exponential decay provides a fairly good fit to the data. ... What about the dark tails seen just above some of the traps? ... For example, the dark tail decay rate for trap 2-337 is only about 3% while the bright tail decay rate is 19%. ...

... My research interests include the compositions of extrasolar rocky objects and the fate of planetary systems around white dwarfs. ... This process often creates a hot dust disk very close to the white dwarf. Measuring the atmospheric compositions of externally-polluted white dwarfs can provide unique information about the composition of those extraterrestrial material. ...
