Query: A search for variable subdwarf B stars in TESS Full Frame Images II.
  Variable objects in the northern ecliptic hemisphere   We report the results of our search for pulsating subdwarf B stars in Full
Frame Images collected during Year 2 of the TESS mission and covering the
northern ecliptic hemisphere. This is a continuation of our effort we presented
in Paper I. We found 13 likely new pulsating subdwarf B stars, 10 pulsating
candidates that are identified as other hot subdwarfs, and 30 spectroscopically
unclassified objects that show amplitude spectra typical of pulsating subdwarf
B stars. We found 506 variable objects, most of them spectroscopically
unclassified, hence their specific variability class yet to be confirmed.
Eclipsing binaries with sharp eclipses sample comprises 33 systems. For 12 of
them we derived precise orbital periods and checked their stabilities. We
identified one known and five new candidate HW Vir systems. The amplitude
spectra of the 13 likely sdB pulsators are not rich in modes, hence any further
analysis is not possible. However, we selected three candidates for pulsating
subdwarf B stars that show the richest amplitude spectra and we performed a
mode identification deriving modal degrees of most of the detected modes. In
total, in both ecliptic hemispheres, we found 15 likely pulsating pulsating
subdwarf B stars, additional 10 candidates for pulsating subdwarf B stars, 66
other variable subdwarf B stars, 2076 spectroscopically unconfirmed variable
stars, and 123 variable non-sdB stars.
