... Figure: Massive binary evolutionary track. ... A short glance to this track is sufficient to understand that there are a lot of evolutionary scenario parameters, which affect different stages of the binary evolution. Fortunately, a very limited number of parameters has effect on the compact binary merging rate. ... The most important (and practically unique) parameter changing the galactic binary NS merging rate is the distribution of an additional (kick) velocity imparted to NS at birth. ...

In this talk I give an introduction to generalizations of the Riemann zeta function called "Weyl group multiple Dirichlet series". Weyl group multiple Dirichlet series are sums in several variables whose coefficients involve Gauss sums and also reflect the combinatorics of a given root system. ... These functions and their residues unify and generalize a number of examples which have been previously treated individually, often with applications to number theory. ...

The variations of the orbital period of the RS CVn-type binary system SZ Psc are examined through a detailed description of the O-C diagram and the use of a new analysis technique. Continuous changes of very large magnidude have been found. ... A combination of a magnetic activity cycle mechanism and an enhanced stellar wind are found to reproduce satisfactorily the period changes. Key words: orbital period variations - mass transfer - mass loss - third body - magnetic activity ...

ATMoB "Open Cluster Observing Award " Guidelines Purpose: To promote observing among the membership of the Amateur Telescope Makers of Boston through participation in the Open Clusters Observing Awards program. Introduction: This awards program is oriented towards visually observing open clusters above magnitude 9.9. ... It turns out that a very unprejudiced and convenient method to dermine the limiting magnitude is to count the number of visible stars in certain areas on the sky. ...

The NTP Version 3 daemon currently supports several different radio, satellite and modem reference clocks plus a special pseudo-clock used for backup or when no other clock source is available. Detailed descriptions of individual device drivers and options can be found in the Reference Clock Drivers page. Additional information can be found in the pages referenced there, including the Debugging Hints for Reference Clock Drivers and How To Write a Reference Clock Driver pages. ...

... Historical Background VizieR was first presented at the AAS meeting in early 1996 (Ochsenbein et al. 1995), as the result of a joint e#ort between CDS 2 and ESA­ESRIN 3 (the European Space Agency's Information Systems division) in order to provide the astronomical community with a dedicated tool for retrieving astronomical data listed in published catalogs and tables --- a follow­up of the ESIS (European Space Information System) project. ...

About us . ... Telescopes . ... Apart from the 6-meter telescope BTA two small telescopes are operative at SAO: the 1-m and 0.6-m telescopes, both manufactured by Carl Zeiss, Jena, are located near the BTA. ... These telescopes are used for adjusting the equipment and techniques of observations used at the BTA. ... The observational time allocation and also a brief description of the equipment of the 1-m telescope, which is used either permanently or mainly on this telescope, are presented below. ...

... Launch Date: 1966-08-10 . ... The Lunar Orbiter 1 spacecraft was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. ... The spacecraft was placed in a cislunar trajectory and injected into an elliptical lunar orbit for data acquisition. ... An 80-millimeter lens system was used to obtain Medium-Resolution (MR) photos, and a 610-millimeter lens system was used for High-Resolution (HR) photos. ...

... A correlation between metal abundance and orbital elements (the eccentricity and angular momentum) has been found for three semples of disk stars of our Galaxy with abundance derived from detailed analysis. The correlation indicates that metal abundance in the Galaxy kept increasing after the birth of old disk stars and that the Galaxy kept collapsing during the formation of its disk subsystems. ...

NAME apachectl - Apache HTTP server control interface SYNOPSIS apachectl command [.. DESCRIPTION apachectl is a front end to the Apache HyperText Transfer Protocol (HTTP) server. It is designed to help the adminis- trator control the functioning of the Apache httpd daemon. NOTE: If your Apache installation uses non-standard paths, you will need to edit the apachectl script to set the appropriate paths to your PID file and your httpd binary. See the comments in the script for details. ...
