Detailed structure of low-density molecular gas in high-latitude clouds.
SAKAMOTO S.
Abstract (from CDS):
We unexpectedly discovered in the position-velocity diagrams a number of localized velocity shifts. Their typical size is 0.05 pc, and some of them exhibit a velocity gradient of ∼40 km.s–1 pc–1, which is among the largest ever observed in non-star-forming clouds. None of them have young stellar objects in their vicinity. Contraction of shock-compressed gas may produce rapidly rotating/contracting, but apparently unbound, clumps. These features may provide more evidence for structure formation through thermal instability of shocked gas.
