# Analysis of eight binaries in Lyncis constellation: RV Lyn, AA Lyn, AH Lyn, CD Lyn, CF Lyn, DR Lyn, EK Lyn, and FS Lyn

## TL;DR

This study presents the first light curve analysis of eight eclipsing binaries in the Lyncis constellation using WASP data, revealing third light contributions and potential third bodies in some systems.

## Contribution

First light curve analysis of eight Lyncis binaries using WASP data, including detection of third light and possible third body in CD Lyn.

## Key findings

- Most systems are detached with periods 0.54-2.3 days.
- Third light detected in AA Lyn and CF Lyn.
- Possible third body in CD Lyn with ~59-year period.

## Abstract

The available photometry mainly from the WASP database was used for the first light curve analysis of eight eclipsing binary systems located in the Lyncis constellation: RV Lyn, AA Lyn, AH Lyn, CD Lyn, CF Lyn, DR Lyn, EK Lyn, and FS Lyn. Most of these eclipsing stars are detached ones, having the orbital periods from 0.54 to 2.3 days. For the systems AA Lyn and CF Lyn a non-negligible third light was detected during the light curve solution. Moreover, 284 new times of minima for these binaries were derived, trying to identify the period variations. For the system CD Lyn a hypothetical third body was detected with the period of about 59 yr.
