The project is successfully over. However, results and data will be used in the future.

This Spectroscopic and photometric survey of the northern fields provides important information for the preparation of the ESA PLATO mission. This is an observation based survey whose main task is to observe the stars in the selected fields in northern sky using spectroscopy and photometry. For the spectroscopic observations we used the Vilnius University Echele spectrograph (VUES) mounted on the 1.65 m telescope at the Moletai Observatory of Institute of Theoretical Physics and Astronomy, Vilnius University. To gather photometric data we used the 35/51cm Maksutov-type telescope.  

In the first data release, the results from the spectroscopic part of the survey described the observations and results of the bright stars in the PLATO STEP02 field. All 213 F, G, and K spectral type main sequence stars brighter than V<8 mag have been observed, 140 of them were slow rotators.

For the second data release we observed the selected 192 stars in the PLATO NPD field among which 109 were slow rotators that were chosen for further analysis. Radial velocities and possible binarity were evaluated by performing a cross correlation function analysis on all the spectra.

For the photometric part of the survey, we have acquired 24470 CCD images and investigated stars brighter than Gaia G 15.8 mag. We accomplished time series analysis for  3598 objects.

Results of the project were presented in 8 papers at high impact factor journals, at 6 international conference proceedings, 6 oral presentations (among them two invited), 9 poster presentations and in a number of outreach activities.
