Next: Period Determination . Period Analysis The combination of the X--ray and photometric observations have produced two samples of low mass PMS stars. At the time that the stars were monitored for rotational modulation, their photometric and spectroscopic properties were not yet known. ... By measuring the rotational periods of the stars in the two samples, one can separate out the effects of age on the rotation period from those of other factors such as mass. Period Determination . ...

During all period of our investigations Dr. N.Sumzina from the Institute of Applied Astronomy of RAS had prepared the Numbered Minor Planet positions from MPC Database for our processing with kind permission of the Director of Minor Planet Center Prof. Braian Marsden. ... Our extensive processing of the MPC data allows us to conclude that CCD observations of the Numbered and Unnumbered Minor Planets have the errors, sometimes very crude. ...

... 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"). ...
