On the possibility of an astronomical detection of chromaticity effects in microlensing by wormhole-like objects

TL;DR

This paper investigates the potential to detect chromaticity effects caused by wormhole-like objects in microlensing events, focusing on color changes and the feasibility of observing these effects with current methods.

Contribution

It introduces a study of chromaticity effects in wormhole-like microlensing and evaluates the detectability of color curves using difference image analysis.

Findings

Color changes depend on blending and source extension.

Detection of color curves is potentially feasible with current observational techniques.

Comparison with limb darkening effects highlights unique signatures.

Abstract

We study the colour changes induced by blending in a wormhole-like microlensing scenario with extended sources. The results are compared with those obtained for limb darkening. We assess the possibility of an actual detection of the colour curve using the difference image analysis method.
