... 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. ...

... Initially SAI Supernova Catalogue was presented in the form of filebased system. ... The current version of SAI Supernova Catalogue presents data on supernovae together with data on their parent galaxies. ... The main source of data for the galaxies was LEDA database. ... In some cases our data were compared with the ones from the Asiago Supernova Catalogue and from List of Supernovae at Harvard-Smithsonian Center for Astrophysics, but the compilation of our Catalogue is carried out independently. ...

... The absolute Galois group of Q, denoted Gal(\bar{Q}/Q) in the sequel, is a fundamental object in arithmetics since it carries a lot of informations about number fields. ... A classical way to study this group is to use p-adic numbers. ... firstly, we will explain the classical d vissage of Gal(\bar{Q_p}/Q_p) based on ramification theory; as a corollary, we will deduce that any finite extension of Q_p is resoluble; . ...

Next: Summary Up: The Second EGRET Catalog Previous: Upper Limits for . In regions of the sky where two or more sources have overlapping point spread functions, it is often difficult to resolve the number of sources and their locations. ... As an example, Nolan et al.(1995) list a source 0445+62 at l = 146.89 , b = 10.65 , with a = 4.0 and a source 0500+59 at l = 150.52 , b = 10.25 , with a = 4.2. ... Both of these sources lie close to the threshold adopted for this catalog. ... 1995). ...

You should define a different target whenever a different target position or timing description is required. For example, separate targets should be defined if you plan to take spectra of several different surface features on a planet, or if you plan to observe the same feature with different timing constraints. ...

... Formulas are very similar to equations. Consider for now only equations with one unknown variable , denoted by some letter, which can be x but can also be different. An equation is an equality between two mathematical expressions containing the unknown number (maybe in several places), as well as other numbers which are known. ... For instance--if you multiply two sides of a formula by the same number, the result is still a valid formula, even if what you multiply contains unknown numbers. ...

Unknown numbers are usually represented by letters of the alphabet . ... However, different letters are also used, often hinting at the quantity they represent-- v for an unknown velocity, T for an unknown time, m or M for unknown masses and F for an unknown force. ... An example of case (#1) is the ratio between the length of a circle and its diameter, a universal constant appearing in many equations (for example, Kepler's equation in section (12a)), whose value to 11 decimals is 3.14159265359.. ...
