... 8, ``Celestial Mechanics'', 2002 Dynamic evolution of resonance orbits of exoplanets in system 47 Uma B. R. Mushailov, A. A. Kaloshin Sternberg Astronomical Institute, Moscow, Russia The orbits of the major and minor planets of the Solar system indicate that their dynamic evolution is essentially influenced by the effects of orbital reso­ nance interactions. ... One may expect that the orbital resonances can exist not only in the Solar system, but also in other star systems. ...

... Gomez, J. C., Athanassoula, L., Fuentes, O., & Bosma, A. 2003, in ASP Conf. ... In this work we present Evolution Strategies (ES) as an efficient method to approximate the initial conditions of the main interacting group of three galaxies in M81. ... In this first attempt we use non-self-gravitating simulations to approximate the initial conditions; even with that restriction our method reproduces the density distribution of the three galaxies with great precision. ...

Ребята,в том то и дело,я ставлю на свои 150 мм 24 мм окуляр на луну и также ставлю на виксен 110 тот же окуляр,на виксене даже глаза болят от яркости,а на целестроне хоть бы хны,нет такой яркости. ...

... Future seminars . ... Long -term evolution of 27 days signal in solar activity and terrestrial magnetic indices - common features and differences ". ... The 27-day signal created by the solar rotation is reflected by the 27-day geomagnetic signal. We study the long-term evolution of the 27 days signal and compare its properties for solar and geomagnetic activity. ... We obtain that 'short' and 'long' period in the 27-days range are differently reflected in the solar and geomagnetic activity. ...

... According to the current estimates, a few percent of Main Sequence B5-F5 stars reveal strong surface magnetic fields reaching the values of tens of kilogauss, which is an order of magnitude greater than the maximal magnetic field in sunspots. ... An important direction in the study of magnetic stars is the study of binary and multiple systems with magnetic components using the techniques of spectroscopy and high angular resolution interferometry. ...
