... Active Region 1002 on an Unusually Quiet Sun . ... Our Sun has shown few active regions -- that house even fewer associated sunspots -- for over a year now, and such a period of relative calm is quite unusual. What is well known is that our Sun is in a transitional period between solar cycles called a Solar Minimum , where solar activity has historically been reduced. ...

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

New 12CO J = 4-3 and 13CO J = 3-2 observations of the N 159 region, an active site of massive star formation in the Large Magellanic Cloud, have been made with the NANTEN2 and ASTE submillimeter telescopes, respectively. ... The 13CO J = 3-2 data were newly taken for the present work. ... The N 159 E clump is associated with cluster(s) embedded, as observed at 24нјm by the Spitzer MIPS, and the derived high temperature, 80 K, is interpreted as being heated by these sources. ...

... ATCA provides the evidence for star formation fuelled by atomic gas inflowing from the outer space . ... On the other hand, with our ATCA observations we found significant amounts of atomic gas, which suggests that the connection between atomic gas and star formation is stronger than previously thought. These observations provide the tantalising evidence that star formation is fuelled directly by atomic gas after accreting metal-poor gas from the intergalactic medium. ... today * ATNF | ...

We review the evidence, from rotational modulation, for association of plages and spots on active binaries. ... There is a similar lack of evidence for BY Dra systems. The results can be interpreted as evidence for: (a) the presence of active longitudes which persist on some RS CVn stars for several years, (b) high filling factors in MgII emission and (c) lower filling factors, and therefore greater contrast, in SWP emission. ...
