On Using the Rossiter Effect to Detect Terrestrial Planets

TL;DR

This paper investigates using the Rossiter effect in spectroscopic velocity shifts to confirm Earth-sized planets, offering a potential method for validation rather than discovery.

Contribution

It introduces a novel application of the Rossiter effect for confirming terrestrial planets in spectroscopic data.

Findings

Detection of Earth-sized planets via Rossiter effect is feasible under optimistic conditions.

Method is suitable for confirming suspected planets, not initial discovery.

Potential to improve validation of terrestrial exoplanets.

Abstract

We explore the possibility that the transit signature of an Earth-size planet can be detected in spectroscopic velocity shifts via the Rossiter effect. Under optimistic but not unrealistic conditions, it should be possible to detect a large terrestrial-size planet. While not suitable for discovering planets, this method can be used to confirm suspected planets.
