Detecting Exoplanets by Gravitational Microlensing using a Small Telescope

TL;DR

This paper demonstrates that small telescopes equipped with CCD cameras can effectively detect exoplanets through gravitational microlensing, a technique suitable for observing distant objects up to 7 kiloparsecs away.

Contribution

It introduces a practical approach using small telescopes for gravitational microlensing, expanding the accessibility of exoplanet detection methods.

Findings

Small telescopes can detect low-mass exoplanets via microlensing.

Effective observational techniques with modest equipment are feasible.

Potential for widespread use in exoplanet surveys.

Abstract

Gravitational microlensing is a new technique that allows low-mass exoplanets to be detected at large distances of ~7kpc. This paper briefly outlines the principles of the method and describes the observational techniques. It shows that small (e.g. 0.35m) telescopes with a CCD camera can make unexpectedly useful observations of these events.
