The eclipse timings of RR Lyncis
Christopher Lloyd
TL;DR
This paper re-examines the eclipse timings of RR Lyncis using TESS data, attributing observed timing variations mainly to pulsations affecting the eclipse profiles rather than asymmetries.
Contribution
It provides a detailed analysis of eclipse timing variations in RR Lyncis, highlighting pulsations as the primary cause of observed differences.
Findings
Eclipse timing variations are linked to pulsations.
Irregular changes in eclipse profiles are observed.
Light-curve asymmetries are not the main cause.
Abstract
The times of minima of the bright, eccentric eclipsing binary RR Lyncis are re-investigated. From the TESS data it is found that significant differences in the eclipse timings, particularly for the primary minima, are probably due to small, irregular changes in the eclipse profile due to pulsations, rather than light-curve asymmetries.
