Cluster and Double Star observations of dipolarization
We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC1) were located in the same local time sector: 7 August 2004, 18:00–24:00 UT, during a disturbed southward/northward IMF interval, and 14 August 2004, 21:00–24:00 UT, when the IMF was stably northward. Cluster observed dipolarization as well as fast flows during both intervals, but this w...
متن کاملObservations and Theory of Star Cluster Formation
Young stars form on a wide range of scales, producing aggregates and clusters with various degrees of gravitational self-binding. The loose aggregates have a hierarchical structure in both space and time that resembles interstellar turbulence, suggesting that these stars form in only a few turbulent crossing times with positions that map out the previous gas distribution. Dense clusters, on the...
متن کاملCoordinated Cluster/Double Star and ground-based observations of dayside reconnection signatures on 11 February 2004
A number of flux transfer events (FTEs) were observed between 09:00 and 12:00 UT on 11 February 2004, during southward and dawnward IMF, while the Cluster spacecraft array moved outbound through the northern, highaltitude cusp and dayside high-latitude boundary layer, and the Double Star TC-1 spacecraft was crossing the dayside low-latitude magnetopause into the magnetosheath south of the eclip...
متن کاملNear-simultaneous magnetotail flux rope observations with Cluster and Double Star
We present observations of three magnetic flux ropes in the tail of the Earth’s magnetosphere on 7 August 2004 by the Cluster and Double Star TC-1 spacecraft. The first two flux rope signatures were observed, nearsimultaneously, by Cluster and TC-1, which were located at (–16.3, –8.7, 0.10)RE GSM and (–10.3, –7.11, 0.81)RE GSM, respectively, a separation of 6.3RE . A third signature was observe...
متن کاملThe physics and modes of star cluster formation: observations.
Stellar clusters are born in cold and dusty molecular clouds and the youngest clusters are embedded to various degrees in a dusty dark molecular material. Such embedded clusters can be considered protocluster systems. The most deeply buried examples are so heavily obscured by dust that they are only visible at infrared wavelengths. These embedded protoclusters constitute the nearest laboratorie...
