... Suppose that an accreting plasma penetrates the light cylinder and is stopped by the magnetic field   at a certain distance given by the balance between the static magnetic field pressure and the plasma pressure. ... Otherwise, a centrifugal barrier emerges and the rapidly rotating magnetic field impedes the accretion of matter (Schwartzman, 1970a[ 173 ]; Pringle and Rees, 1972[ 164 ]; Davidson and Ostriker, 1973[ 38 ]; Lamb et al. ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...

ST-ECF Technical Instrument Report WFC3-2009-04 The cross dispersion profiles of the WFC3 grisms H. Kuntschner, H. Bushouse, M. KЭmmel, J. R. Walsh April 30, 2009 ABS TRACT This document summarizes the analysis of the cross-dispersion profile width for the three grisms of the WFC3. For the IR grisms, the cross dispersion profile width derived from white light images and monochromator steps obtained in TV3 provide consistent results also in agreement with estimates derived from direct images. ...
