英文摘要 | Pulsating stars in eclipsing binaries are very important for understanding the structure of stellar interiors through asteroseismology because their absolute parameters such as their masses and radii can be determined with high precision based on photometric and spectroscopic data. The high-precision and continuous time-series photometric data of the Transiting Exoplanet Survey Satellite (TESS) provides an unprecedented opportunity to search for and study these kinds of variable stars in the whole sky. About 1626 Algol-type (EA-type) eclipsing-binary systems were observed by TESS in the 1-45 sectors with 2 minutes short cadence. By analyzing these TESS data, we found 57 new pulsating stars in EA-type binary stars. The preliminary results show that these binary systems have orbital periods in the range from 0.4 to 27 days, while the periods of pulsating components are in the range from 0.02 to 5 days. It is detected that 43 targets follow the correlation between the pulsation and orbital periods of Algol-type oscillating eclipsing binaries (oEA stars), which may indicate that they are typical oEA stars. The other 14 targets may be other types of variable stars in eclipsing-binary systems. These objects are a very interesting source to investigate binary structures and evolution as well as to understand the influences of tidal forces and mass transfer on stellar pulsations. |
