  Hot subdwarf B (sdB) stars are evolved, subluminous, helium-burning stars,
most likely formed when red-giant stars lose their hydrogen envelope via
interactions with close companions. They play an important role in our
understanding of binary evolution, stellar atmospheres, and interiors. Within
the sdB population, only a small fraction are known to exhibit pulsations.
Pulsating sdBs have typically been discovered serendipitously in various
photometric surveys, lacking specific selection criteria for the sample.
Consequently, while individual properties of these stars are well-known, a
comprehensive understanding of the entire population and many related questions
remain unanswered. The introduction of Gaia has presented an exceptional chance
to create an unbiased sample by employing precise criteria and ensuring a high
degree of completeness. The progression of high-precision and high-duty cycle
photometric monitoring facilitated by space missions such as Kepler/K2 and the
Transiting Exoplanet Survey Satellite (TESS) has yielded an unparalleled wealth
of data for pulsating sdBs. In this work, we created a dataset of confirmed
pulsating sdB stars by combining information from various ground- and
space-based photometric surveys. Utilizing this dataset, we present a thorough
approach to search for pulsating sdB stars based on the current Gaia DR3
sample. Using TESS photometry, we discovered 61 new pulsating sdB stars and 20
variable sdBs whose source of variability remains to be determined through
future spectroscopic follow-up observations.
