Abstract:
Based on 2 minute cadence TESS data from sectors 1-50, we report the
results of the systematic extraction of δ Scuti-type pulsations
in the 6431 eclipsing binaries with orbital periods shorter than
13days. A total number of 242 pulsators were found in those systems,
including 143 new discoveries. We examined their pulsation properties
based on the H-R diagram and the relationships between the dominant
pulsation period Pdom, orbital period Porb, and effective temperature
Teff. As a consequence, 216 targets are likely δ Scuti stars
(123 new), 11 likely γ Doradus-δ Scuti hybrid stars (8 new),
5 likely β Cephei stars (4 new), 4 likely δ Scuti-γ
Doradus hybrid stars (3 new), 3 likely Maia stars (3 new), 2 likely
pulsating red giants (1 new), and a new unclassified star. As for the
six new δ Scuti pulsators in eclipsing binaries with
Porb<0.65d, we found that three of them significantly exceed the
upper limits of the Pdom/Porb ratio. This may indicate that Pdom and
Porb are uncorrelated for them. Finally, we statistically analyzed the
dominant pulsation periods of the 216 δ Scuti stars in eclipsing
binaries. Those stars concentrate around 225µHz and the proportion
of stars in the high-frequency region is significantly higher than
that of single stars, which could be ascribed to the mass-transfer
process.
Description:
For the 6431 eclipsing binaries with Porb<13days from the catalogs
of Prsa+ (2022, J/ApJS/258/16), Shi+ (2022, J/ApJS/259/50), and
Ding+ (2022; PASJ, submitted), we downloaded the 2 minutes cadence
photometric data from sectors 1-50 (2018-Jul-25 to 2022-Apr-22) from
the TESS Asteroseismic Science Operations Center.
