The third body in the eclipsing binary AV CMi: Hot Jupiter or brown dwarf?

TL;DR

This study analyzes new transit light curves and re-derives system parameters of AV CMi to determine whether its third body is a Hot Jupiter or a brown dwarf.

Contribution

It combines multiple light curve analyses to investigate the nature of the third body in the AV CMi system, providing new insights into its classification.

Findings

The third body could be a Hot Jupiter or a brown dwarf.

Re-analysis of light curves refines system parameters.

Combined analysis suggests the third body's nature is ambiguous.

Abstract

New transit light curves of the third body in the system AV CMi have been obtained. The eclipsing pair's light curves were re-analysed with the W-D code and new absolute elements were derived for the two components. Moreover the new light curves (together with those given by Liakos & Niarchos 2010) of the third body transiting one of the components were analysed with the Photometric Software for Transits (PhoS-T). The results from both analyses are combined with the aim to study the nature of the third component.
