Next: Identification and Analysis of Binary Star Systems using Probability Theory . ... We present a computing code for modelling energy flux distributions, photometric indices and spectral line profiles of (non-)radially pulsating Main-Sequence stars. ... In the case of slowly rotating stars one can use the zero-rotation approximation to describe stellar pulsations. Such a model was used already by Cugier, Dziembowski & Pamyatnykh (1994) to study nonadiabatic observables of Cephei stars. ...

In 2002ApJ?580.1118K , we dealt with modeling the photon arrival time differences as due to flares occuring at random times but with a power-law intensity distribution with index alpha. physics/0706.1758 deals with time-between-touches and tries to characterize that distribution itself in terms of a number of ?phases? beta. ...

... 1 Space Research Institute, Moscow, Russia . ... Classic concept of magnetic merging is represented by pair of flux tubes originating from two interacting magnetic fields reconnected at X-line. This type of reconnection between interplanetary magnetic field and magnetospheric magnetic field received very substantial confirmation from observations. ... We use Interball-Tail observations of ion velocity distributions within magnetospheric boundary layer as tracers of magnetic topology. ...

THE CHEMICAL COMPOSITION OF REGOLITH AT THE MOON'S SOUTH POLE, ACCORDING TO DATA OF LUNAR PROSPECTOR AND LUNAR RECONNAISSANCE ORBITER MISSIONS. ... Introduction: The article tells about the results of integrated study of the craters at the Moon's South Pole with permanently shadowed region of craters. ... We have compared the ultimate composition of the soil matters in the craters with "cold traps" in the Moon's South Pole with regard to thorium, ferric oxide and hydrogen contents (Fig. ...

... For eight samples of main-sequence disk stars, the metallicity indices 0.6 , R-1 (U-V), m1 ( ) have been calculated. The indices 0.6 and (U-B) have been calibrated to the metal abundance [Fe/H] for the spectral types F, G and K separately. ... It is found that the UBV and RI data for F- and K-dwarfs imply that the metallicity of the Sun coincides with that found for the Hyades, whereas the G-dwarfs give the well known smaller metallicity of the Sun with respect to the Hyades. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

We construct p-adic L-functions as Mellin transforms of certain distributions attached to Euler products. The method of modular distributions makes it possible to construct in many cases such L-functions from the Fourier coefficients of modular forms. ...
