A High School Curriculum in Astrobiology . Astrobiology is a truly integrated science. For example, when extreme environments of Earth are examined as a springboard to the search for life in the Solar System, other subjects?the biology of microorganisms, the chemistry of nutrients, the process of respiration, and the nature of autotrophic habitats?are intimately entwined and must be considered in one breath, albeit a long one. ...

... Several CCD suppliers specify their devices without taking into account the effects of dark current and temperature. ... The influence of dark current is becoming more important, especially with larger integration or storage times at elevated temperatures. ... The temperature will influence the dynamic range through dark current, shot noise on the dark current and temporal noise of the output amplifier. ... Increasing the integration time automatically increases the dark current. ...

... This approach is uniform for all values of the system parameters and applicable to most limb-darkening laws used in astrophysics. In the cases of the linear and quadratic limb-darkening laws, we obtained analytical expressions for the light curve and its derivatives in terms of elementary functions, elliptic integrals and a piecewise-defined function of one variable. ... Besides, they do not allow sufficiently accurate calculations of the light curves for some limb-darkening laws. ...

... We study ergodic properties of random maps defined as collections of nonsingular maps $f_1,\dots,f_w$ from a compact metric space $(X,\rho)$ into itself taken with probabilities $p_1,\dots,p_w$ ($\sum_i^wp_i=1$) and considered as Markov processes on $X$. ... In the first situation, when the random map is expanding on average, we mainly follow ideas borrowed from the theory of piecewise expanding maps and the corresponding Banach space is a version of the space of functions of bounded variation on $X...

To the right of the sidebar and below the header is the "main" area, whose dimensions are computed based on remaining available space. Finally, at the bottom, the "footer" area is 100px high and covers the entire width of the frameset. ...
