The rates of build-up in the atmosphere of human-made compounds that deplete the ozone layer (e.g., chlorofluorocarbons (CFCs) and halons) have slowed in recent years as a direct result of reductions in global emissions of these compounds. ... The peak global ozone depletions are expected to occur during the next several years. ... Methyl bromide continues to be viewed as a significant ozone- depleting chemical. ...

... Actual stars are expected to be more complicated than these simulations. ... The spot may be entirely visible most of the time (one would observe a prolonged flux minimum low), and then part of it may disappear over the horizon briefly and then return (slow rise and then fall back to constant level). ... With the set of observations taken here, I have information available from several comparison stars and color information. ... The period found must be consistent with the data from any given night....

... Andres Guzman F. Universidad de Chile HCHIIR workshop Sydney, 8 Sept 2010 Ionized jets and HCHIIR Both are related to very earl y stages of high mass star formation They share similar characteristics when observed in cm radio continuum They will be confused in some degree depending on which criteria we used to identify young stellar objects Ionized jets and HCHIIR 1) First criterion for identifying early stages: Less radio continuum than expected for a optically thin HIIR Sewilo et al. ...

... The hotter the gas, the faster they move, and the more energy each of them holds. The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much , much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...
