Asteroseismology is a powerful tool to probe stellar interiors and constrain fundamental stellar properties. Currently, the number of dwarfs and subgiants with solar-like oscillations is limited. To expand the sample, we re-analyze Kepler short-cadence data using pySYD, an automated pipeline to extract global asteroseismic parameters. We present 56 new detections in Kepler short-cadence data, increasing the currently known sample of dwarfs and subgiants with solar like oscillations by ~9%. We derive stellar mass and radius using scaling relations. Our new detections greatly improve the sample of asteroseismic benchmark dwarfs and subgiants in Kepler data, and provide a glimpse of the discovery of solar-like oscillators with TESS. This increase in seismic detections will enable precise characterization of planetary systems, and provide new candidates to test gyrochronology models.
