A photometric study of the neglected eclipsing binaries: V405 Cep, V948 Her, KR Mon and UZ Sge

CCD multi-band light curves of the neglected eclipsing binaries V405 Cep, V948 Her, KR Mon and UZ Sge were obtained and analysed using the Wilson–Devinney code. New geometric and absolute parameters were derived and used to determine their current evolutionary state. V405 Cep, V948 Her and KR Mon are detached systems with their components in almost the same evolutionary stage. UZ Sge is a classical Algol system with a tertiary companion around it. Moreover, since the systems V405 Cep, V948 Her and UZ Sge contain an early type component, their light curves were examined for possible pulsation behaviour.

► We observed the binaries V405 Cep, V948 Her, KR Mon and UZ Sge.
► Absolute parameters were derived and used to determine their evolutionary state.
► V405 Cep, V948 Her and KR Mon are detached systems.
► UZ Sge is an oEA system with a tertiary companion around it.
