A magnetic flux tube anchored at the bottom of the solar convection zone and rising toward the surface as a result of an undulatory instability can be affected by a sudden catastrophic expansion and weakening of the magnetic field at its apex if the original field strength is below a few times 104 G. Such an "explosion" occurs if the flux tube

The polarizations of the ϒ (1 S) , ϒ (2 S) , and ϒ (3 S) mesons are measured as a function of the charged particle multiplicity in proton-proton collisions at √{ s} = 7 TeV. The measurements are performed with a dimuon data sample collected in 2011 by the CMS experiment, corresponding to an integrated luminosity of 4.9 fb-1. The results are

We present simultaneous time-resolved photometry and spectroscopy of the eclipsing cataclysmic variable 1RXS J020929.0+283243 (ATel #652). Our data indicate that it is a new AM Herculis (i.e. polar) system. Unfiltered photometry (25-sec time resolution) was performed on 2005 November 8 UT at the 2.56-m Nordic Optical Telescope on La Palma. The

Tenerife is not Jakarta. Neither is 2009 the year 1965, nor the Museo de la Ciencia y el Cosmos (Museum of Science and the Cosmos) the hotel "Indonesia", meeting point of reporters from around the world. Nor am I the journalist Jill Bryant (Sigourney Weaver) in the Australian Peter Weir film. But 2009, a year of international commitment to
