| 摘 要： | The Gaia DR3 parallax approach was used to estimate the absolute parameters of 2375 δ Scuti stars from the ASAS catalog.The selected stars have a variety of observational characteristics,with a higher than 80% probability of being δ Scuti stars.We have displayed all the stars in the Hertzsprung-Russell diagram along with the δ Scuti instability strip,the Zero Age Main Sequence and the Terminal Age Main Sequence.Then,we determined which fundamental and overtone modes each star belongs to using pu...
