Waldmeier of the Swiss Federal Observatory. ... This indicates the uncertainty above and below the predicted number. ...

General Forum Message . Forums: . ... The Telescope's F/number . ... The f/number (focal ratio) of any telescope tells two things about the telescope and that is it's intended purpose and it's photographic performance. The brightness of a star depends on the telescope's aperture not the telescope's f/number. ... The f/number of any objective lens or a mirror of a telescope has nothing to do with the visual brightness of an image, the bigger the aperture the better. ... www.astronomy.net . ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ...

Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

... Номер следующего наблюдения устанавливается всегда автоматически, однако существуют ситуации, когда нужно переустановить номер следующего наблюдения (например, предыдущее наблюдение было ошибочным).

При отсутствии параметра программа сначала покажет старое значение для номера следующего наблюдения, а после этого, запросит новое значение. ...

... The absolute magnitude of the RCBs in the LMC and the small number of Galactic RCBs implies that they are very rare stars. Together with statistics for related stars, the total number of hydrogen-deficient stars in the Galaxy is estimated to be about 1000. Whilst the luminosity of RCBs is similar to that of other low-mass stars as they evolve rapidly from the asymptotic RED GIANT branch to become WHITE DWARFS , their frequency is much lower. ...
