UPPER PANEL: The gas surface density map in log scale. The red circle in the center represents the central protostar. The development of spiral structure in the protostellar disk is evident. Dense protostellar/protoplanetary clumsp form within the spiral arms and are driven into the protostar by the action of gravitational torques. LOWER PANEL: The mass accretion rate onto the protostar as a function of time. The mass accretion rate is characterized by very short ( . ...

... Chapman and Ferraro (1931, 1932) were first to discuss the existence of a boundary to the Earth's magnetic field. During 1950's, as the concept of continuous solar wind emerged, it was obvious that such a feature should be a permanent feature of the magnetosphere . ... At this location, typically around 8 - 11 Re away on the Earth - Sun line, a large scale duskward (Chapman-Ferraro) current develops in the dayside magnetopause to cancel the Earth's field outside. ...

... Searches for Star Formation in Damped Systems . ... The objective was to measure the star-formation rates in these systems. However, no H emission was detected above our limits of Wm -2 , corresponding to star formation rates ( q 0 =0.5). ... For q 0 =0.5 our limits are in conflict with the star formation rates predicted under the assumption that the high- z DLAs are the fully-formed galactic-disk counterparts of today's massive spiral galaxies. ...
