... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...

... We consider stars with a constant (solar) initial chemical composition. Before the Roche lobe overflow, the components evolve as single stars (see for details LPP96). ... If the mass transfer onto a normal star occurs on a time-scale ten time shorter than the thermal Kelvin-Helmholz time for this star or a compact star is engulfed by a giant companion (e.g. as a result of the kick), the common envelope (CE) stage of the binary evolution is set in (Paczynski 1976). ...

Title , Contents , Index . Nested lists can be made from an RTF document by using a different style for each level of indentation. The styles "bullet list 1" "numbered list 2" ... represent different levels of nesting. The only rule for use is that no levels of nesting are skipped. For example, a "ol 3" paragraph must not appear immediately after a "Normal" paragraph. It must follow a paragraph with a nesting level of 2 or higher. ...

... Circles are chemically normal stars, squares are Boo stars, the diamond is the possible Bp star V380 Ori A. Open symbols are stars with confirmed magnetic field detections. ... The photospheres of about 10-20% of main sequence A- and B-type stars exhibit a wide range of chemical peculiarities, often associated with the presence of a magnetic field. ... The incidence of Boo chemical peculiarities we find in Herbig stars is much higher than what is seen on the main sequence. ...

In using what-if questions in the classroom, it is worth bearing in mind that students extrapolating the effects of new scenarios will encounter two different situations: direct changes to the new version of Earth and indirect changes resulting from the direct changes. ...

... They normally have 1 hz resolution. hp1: this is the LO for the rf to if1 mixing (1st lo) . hp2: this is used to generate the 2130 Mhz signal for the sband. 250 Mhz from downstairs gets added to this to generate 2380 Mhz which then drives the sband exciter.
