2. Phil Plait's Bad Astronomy: Bitesize Astronomy
... 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. ...

4. STScI Preprint #1204
... Bright spot spectra have been constructed by differencing the mean spectra observed at pre- and post-eclipse orbital phases. These difference spectra contain ultraviolet absorption lines and show the Balmer jump in emission. ... Model disk spectra constructed as ensembles of stellar atmospheres provide poor descriptions of the observed post-eclipse spectra, despite the fact that UX UMa's light should be dominated by the disk at this time. ... huizinga@stsci.edu . ...

6. All Sky Catalog at 2.7 GHz
... Fractional flux density variations of between 5 and 100 per cent (typically 15-25 per cent) have been detected on a range of time-scales from 1 to 12 years. ... The 151-MHz flux densities have been indirectly scaled to the 6C flux scale. ... Amongst the 72 sources for which the chance of being a true variable is greater than 0.8, typical maximum flux density variations of 15-25 per cent are seen; eight objects show variations greater than 50 per cent, with one source varying by more than 100 per...

7. The galaxy M100
An image of the grand design of spiral galaxy M100 obtained with NASA's Hubble Space Telescope resolves individual stars within the majestic spiral arms. ... Hubble has the ability to resolve individual stars in other galaxies and measure accurately the light from very faint stars. This makes space telescope invaluable for identifying a rare class of pulsating stars, called Cepheid Variable stars embedded within M100's spiral arms. ... 617) 495-7062 . Fax: (617) 495-7356 . ...

... Cataclysmic Variables . ... The main aim of this survey is to discover new stellar binary systems with orbital periods less than ~80 min. ... The intensity of stellar objects can vary on a wide range of time-scales, ranging from seconds to months to years. ... Most of these surveys are sensitive to timescales longer than a day. ... For instance, the 0.3 deg x 0.3 deg survey using the Canada France Hawaii Telescope was sensitive to variations on timescales as short as ~8 min (Lott et al 2002) . ...

10. ASP: A Taste of Real Astronomy ? The ESA/ESO Astronomy Exercises
The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

11. Blue Straggler Stars
... BLUE STRAGGLER STARS are unusually hot and bright stars found in the cores of ancient star clusters known as globulars. ... BACKGROUND (from wikipedia): Blue straggler stars are stars in open or globular clusters that are hotter and bluer than other cluster stars having the same luminosity. ... There is evidence in favor of this view, notably that blue straggler stars appear to be much more common in dense regions of clusters, especially in the cores of globular clusters. ...

This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 is the deepest ever made of any cluster of galaxies. ... It contains several hundred galaxies as they looked 3.5 billion years ago. The immense gravity in Abell 2744 acts as a gravitational lens to warp space and brighten and magnify images of nearly 3,000 distant background galaxies. The more distant galaxies appear as they did longer than 12 billion years ago, not long after the Big Bang. ...
