... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

System of astrometric databases of Pulkovo observatory. ... The purpose of these observations is the determination of precise coordinates of Solar system bodies, which is necessary for development and improvement of motion theories, and for studying the evolution of the Solar system. ... Accuracy of photographical observations is about 0.2-0.3 arcsec for equatorial coordinates and 0.1-0.3 for relative coordinates of planetary satellites, depending on object and observational conditions. ...

... From the uvby photometry and proper motions for about 5500 nearby F stars we have found the following: (i) F stars , taken in narrow ranges of metallicity , show at [fe/H] 0 rather distinct cut-off in their distribution along the Main Sequence (MS) at the blue side, which is suggested to be an indication for the MS turn-off in stellar groups of fixed metallicity ; (ii) the corresponding turn-off age from theoretical isohrones strongly correlates with the ...

... Impedance . Electrical impedance, or simply impedance, describes a measure of opposition to a sinusoidal alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. ... Resistance is the real part of impedance; a device with a purely resistive impedance exhibits no phase shift between the voltage and current. ...

GRANAT is the Russian x-ray sattelite launched to the high apogee orbit (200,000 km) and operated almost for 10 years (1989 -1999) , carrying out four major instruments: French SIGMA coded-mask hard x-ray telescope (30-1000 keV), Soviet ART-P coded-mask telescope (2??-60?? keV), all-sky monitor WATCH (6-150 keV), and a gamma-burst detector PHEBUS . ...
