... November s Lunar Eclipse . ... Almost out of view from our fair planet, rotating around the Sun's western edge, giant sunspot region AR 10486 lashed out with another intense solar flare followed by a large coronal mass ejection (CME) on Tuesday, November 4th at about 1950 Universal Time. ...

... However, the comparison of masses deduced from the continuum SIMBA 1.2 mm emission and virial masses (understood to trace the entire potential of the clouds) in a sample of giant molecular clouds in the Small Magellanic Cloud (SMC) by previous studies found a discrepancy between these two quantities that requires explanation. ... Methods: New observations of the southwest region of the SMC were obtained with the LABOCA camera on the APEX telescope. ...

... 640W A survey of ultracompact (UC) Hii regions has been carried out by searching for 6.669-GHz methanol maser emission from a sample of 535 IRAS-selected candidates. A total of 201 candidates exhibit methanol emission. These sources have been used, in conjunction with previously identified UC Hii regions, to provide a base for further studies of such regions. ... Methanol maser and/or radio continuum emission is found in 364 cases towards IRAS-selected regions. ...

... The total pressure P in a non-degenerate, ionized region of a not-too-luminous star can be considered as that of a simple perfect gas alone (i.e. radiation pressure can be ignored). ... Similarly, the energy density per unit mass is U = 3 k T /µmH . Using the 1st Law of Thermodynamics, 2 show that in this region of the star, the adiabatic exponents 1 , 2 and 3 are all equal to 5 , 3 where the exponents are defined as 1 = ( d ln P )ad , d ln ad d ln T 2 - 1 =( ) 2 d ln P and 3 - 1 = ( d ln T )ad . ...

... We assume that an instantaneous starburst occured in the region of the Galactic center, with half of the stars (in number) being formed in binaries. The total mass of the stars formed during the starburst was taken to be , as indicated by the Tamblyn & Rieke (1993) analysis. ... In fact, the number of stars in IRS 16 estimated by Tamblyn & Rieke (1993) is uncertain within a factor of 2, but this is actually of no importance as long as we only use relative numbers of different X-ray source species. ...

Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...
