... LINEAR s Tail and Two Nuclei . ... 31.05.2001 . ... Credit Copyright Gordon Garradd , Loomberah NSW Australia Explanation: Arcing toward southern skies in late March, this faint comet LINEAR - the one officially designated C/2001 A2 (LINEAR) - brightened unexpectedly. The outburst, apparently due to the fragmentation of its nucleus, delighted observers as the comet eventually increased to naked-eye brightness. ...

. Figure 2: Sequence of events after an oblique impact: (a) Object impacts another and generates a shock wave; (b) and (c) increased development of two prominent features, i.e., a downrange plume and conical impact ejecta. The downrange plume results from the fragmentation or sometimes the evaporation of the impacting object while the conical impact ejecta come from the physical destruction of the impacted object when the shock wave spreads from the site of impact and scoops up materials from it.

... A molecular cloud in the interstellar medium may be considered as spherical and of uniform density and fixed temperature as it undergoes expansion or contraction. Assume the opacity of material in the molecular cloud has a value . ... How will this affect cloud fragmentation? (e) In the stages of collapse of a gas cloud before it becomes optically thick, its temperature is determined by the balance between compressional heating and radiation of energy from the cloud. ...
