We present the detection and analysis of molecular hydrogen emission towards ten interstellar regions in the Large Magellanic Cloud. We examined low-resolution infrared spectral maps of 12 regions obtained with the Spitzer infrared spectrograph (IRS). ... The excitation diagrams of the detected H2 transitions are used to determine the warm H2 gas column density and temperature. ... We find the excitation of H2 by this process is equally efficient in both atomic- and molecular-dominated regions. ...

... The dayside auroral precipitation consist of magnetosheath related boundary layer precipitation, and plasma sheet related BPS/CPS precipitation (extensions of the nightside precipitation regions). ... For example, the much lower fluxes from the LLBL region when compared to the cusp are compensated by the bidirectional electron beams found in the LLBL: the precipitating energy fluxes in the LLBL and the cusp are not that different. ... directly through the cusp and plasma mantle . ...

These data may be used to constrain models both of photodissociation regions and of fluorescent excitation for molecular hydrogen. ...

... This study reveals for the first time the existence of bi-directional jets, which are a signature of magnetic reconnection, occurring along coronal hole (CH) boundaries. ... K) emission lines in an equatorial extension of a polar coronal hole, known as the ``Elephant's Trunk'' coronal hole, show small regions of a few arc-seconds size with strong blue- and red-shifted emission reaching Doppler shifts of up to 150km s, i.e. bi-directional jets. ...

... Obviously, the size of the cavern is of the order of the Schwartzman radius. ... Thus, consideration of the inverse effect of pulsar radiation on the properties of accreting plasma makes the ejection possible even when the Schwartzman radius is smaller than the capture radius. ... If the cavern radius , the condition at its boundary can be written as . ... Apart from magnetic dipole radiation, the cavern may also contain relativistic particles (which are also reflected from the cavern boundary). ...

... Bloch proves that the second Chern class of a vector bundle with trivial determinant can be obtained by boundary homomorphism for the universal central extension of the sheaf SL(O_X). I use this construction to get an adelic formula for the second Chern class in terms of trivializations in scheme points. I also introduce some extension of St(A) for any ring A by diagonal matrices which allows us to generalize Bloch formula to vector bundles with general determinant. ...
