... Development of Mini-MegaTORTORA (MMT) - a multichannel wide-field optical monitoring system with high temporal resolution . ... The MMT system is a robotic multichannel (9-objective) optical telescope with an approximate field of view of 900 square degrees and a temporal resolution of 0.1 seconds, equipped with a system of accumulation, analysis and storage of observed data. ... The list of objects and the observed material is supplemented and updated by new and archived observational data. ...

Next: Rotation Periods of ZAMS stars Previous: T Tauri Stars . ... The first attempts to directly measure periodic modulation of T Tauri stars occurred in the early 1980s. Rydgren & Vrba (1983) observed four PMS stars using photoelectric photometry over a period of seven consecutive photometric nights. ... Because the spot lifetime is much longer than the rotational period, the observed effect will be a modulation of the light from the star synchronously with the rotation period. ...

... CI Cam is known to be a B[e] star and X-ray transient source. ... Figure 1. The light curve of CI Cam in residuals relative to the mean level of the slow variability (top) . The radial velocity curve of the HeII emission (middle) . ... The V light curve is shown in Figure 1 (top). ... Comparison of two CI Cam spectra in the region of HeII line. ... The radial velocity curve of HeII in CI Cam has a saw-tooth shape that may be an evidence of an elliptical orbit. ...

... I have considered the following monitors: Nokia445X Nokia 447X Philips 21BA Philips 15A Nec XE17 Nec XP17 Mag MXP17F Mag MXP17S Hitachi CM1711 Samsung 17GLsi My goal was to find a flickerfree monitor. ... The above monitors can do this refresh rate at some resolution. ... Bad) Nec XP17 , expencive and terrible ! ... I have set the refesh rate to: 640x480 115Hz 800x600 115Hz = My default resolution. 1024x768 100Hz 1152x870 95Hz 1280x1024 93Hz The Samsung 17GLsi monitor I have now is not 100% perfect....
