Adopt layout variation that allows camera to be adjacent to compact baseplate supporting other components (XXX diagram). ... Kinematic mounting of optics mounts to baseplate not ruled out, but no need to consider in detail yet (until we decide use of different materials for baseplate and mounts is preferable) . ...

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. ...

Solar Flare Origin - critical analysis" Lev Pusti'lnik We analyze current approach to solar flare origin in 3 aspects: a. Pre-flare equilibrium state of current-magnetic structure above active region and its evolution to flare state, b. Possible reasons of stability loss with transition of system in flare state c. Flare energy release in turbulent current sheet and particle acceleration in this system. ...

THE TEMPERATURE OF NONSPHERICAL CIRCUMSTELLAR DUST GRAINS N.V.Voshchinnikov and D.A.Semenov Astronomy Department and Sobolev Astronomical Institute, St.Petersburg University, St.Petersburg, 198504 Russia ABSTRACT The temperature of prolate and oblate spheroidal dust grains in the envelopes of stars of various spectral types are calculated. ... The temperature ratio T_d (spheroid)/ T_d (sphere) depends most strongly on the grain chemical composition and shape. ...

... THE SIMPLEST MODEL. ... 13, Moscow 119992, Russia E-mail: san@sai.msu.ru Abstract: The analysis of the simplest model shows that an asteroid ­ rubble pile evolves, depending on the parameter V2d (where V is the average velocity of fragments and d is the average distance between fragments), either as a conglomerate of "independent mutually gravitating clusters" (when V2d < fm, where f is the gravitational constant and m is the average mass of a fragment) or as a "receding cluster" (when V2d > fm). ...

... The x-ray spectral analysis consists of a comparison between the observed pulse height spectrum and a pulse height spectrum calculated using a given spectral model. ... To obtain the spectral parameters for an x-ray source, several steps need to be followed. For each source: . ... obtain the best fit parameters for a spectral model - repeated for each model of interest . obtain a 1-D or 2-D grid of values around the best fit values - this can be done for as many models as desired . ...
