... 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 ...

... If the Astrometria project is implemented in time, we will be able to issue a reliable forecast of the time and scale of the upcoming global fall of temperature on the Earth within approximately 8 years by conducting an active research of temporal variations of the shape and diameter of the Sun and of the solar energy flux on-board the ISS during no less than a half of the on-going 24th "short" 11-year cycle. ...
