Asteroseismology is the study of internal structures of stars through their global oscillation modes. Stellar properties can be measured using scaling relations based on asteroseismology of the Sun. Solar properties and measurements are well known through extensive studies, however for red giant stars, anomalies exist between observations and theoretical predictions. The differences between the internal structure of the sun and red giants suggest the necessity of specialized scaling relations. Newly released data by Transiting Exoplanet Survey Satellite (TESS) mission provides great opportunity to increase the amount giants available for analysis to improve giant scaling relations. To better constrain necessary scaling relations, using red giants in binary systems provides multiple avenues for stellar parameter calculations. We seek to isolate new red giants in binary systems exhibiting oscillations that are stochastically excited by convection. After sifting through the first two datasets available with an algorithm catered to each dataset, we analyzed isolated giant star candidates in search for positive oscillation detections. At present, no detected binary systems show oscillations. Our results thus far highlight the potential need for different TESS data for asteroseismology. The search will continue as more data from TESS becomes available.
