GJ 900 - a new hierarchical system with low-mass components E. Malogolovets, Yu. Balega, D. Rastegaev, K.-H. Hofmann, G. Weigelt Speckle interferometric observations made with the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences in 2000 revealed the triple nature of the nearby (d=19.3 pc) low-mass young (age about 200 Myr) star GJ 900. The configuration of the triple system allowed it to be dynamically unstable. ...

2. Principal Components Analysis
... Among the objectives of Principal Components Analysis are the following. dimensionality reduction; љ . the determining of linear combinations of variables; љ . ... identification of groups of objects or of outliers. ... Finding a set of principal axes allows the objects to be adequately characterised on a smaller number of (artificial) variables. ... Reduction of dimensionality is practicable if the first new axes account for approximately 75 % or more of the variance. ...

9. Constraints on the model components:
... The fitting procedure will only converge to a unique solution if the components are linearly independent. ... The task calculates for each pair of component images and fails with an error if any is greater than 0.99. ... Hence components may be linearly independent in masked pixels yet still fail the test within the task. ... Finally, since the Poisson image values are necessarily all , negative values are not allowed in the model components. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

11. Two points (INTERBALL-1 and MAGION-4) observations of magnetopause motion
The close position of main satellite and subsatellite (distance between them about 1000 km) and using the similar sets of Faraday cups (VDP and VDP-S) with high resolution measurements (up to 16 Hz for the main satellite and up to 10 Hz for the subsatellite) allow us to determine the small-scale variations of the magnetopause shape and position and to estimate the velocity of the magnetopause motion. ... Two point observation of the magnetopause motion: the INTERBALL project. ...
