... and on-board accelerometer . ... All these peculiarities of high-orbit SVLBI can be used to increase the sensitivity (longer possible integration time for a given UV-point) and the accuracy of measurements of position of radio sources. ... In this Memo we consider the advanced methods of ground radio telescopes and tracking stations (TS) operation, on-board H-maser frequency standard (SHM - already planned for the mission) and high-accuracy on-board accelerometer applications to solve this objective...
... Panoramic spectroscopy of the sample of 80 nearby lenticular galaxies is presented. ... By comparing the subsample of the S0s with the chemically distinct nuclei to the total sample of nearby S0s (Fig. 1), we have assured that the chemically distinct nuclei are always younger than the surrounding bulges: the mean age difference between the chemically distinct nuclei and their surrounding bulges is 2.8 Gyr while the age difference between the nuclei and the bulges for the whole sample is only 1 Gyr. ...
FF Aqr DW Period is significantly greater than typical value for DW type. According to Pojmanski [45] this star is DCEP-FU: variable. According to Sipahi et al. [263] it is one of the few binary systems which consists of the hot subdwarf and cool chromospherically active giant components. ... Belongs to long-period RS CVn systems, secondary is more massive and more larger (volume of the secondary is approximately 100 times larger than that of the primary component). ... So may be SA system? ...
