The advantages of using a Lucky Imaging camera for observations of microlensing events
MetadataShow full item record
In this work, we study the advantages of using a Lucky Imaging camera for the observations of potential planetary microlensing events. Our aimis to reduce the blending effect and enhance exoplanet signals in binary lensing systems composed of an exoplanet and the corresponding parent star. We simulate planetary microlensing light curves based on present microlensing surveys and follow-up telescopes where one of them is equipped with a Lucky imaging camera. This camera is used at the Danish1.54-m follow-up telescope. Using a specific observational strategy, Foran Earth-mass planet in the resonance regime, where the detection probability in crowded-fields is smaller, lucky imaging observations improve the detection efficiency which reaches 2 per cent. Given the difficulty of detecting the signal of an Earth-mass planet incrowded-field imaging even in the resonance regime with conventional cameras, we show that Lucky Imaging can substantially improve the detection efficiency.
