# The Kilodegree Extremely Little Telescope (KELT): A Small Robotic Telescope for Large-Area Synoptic Surveys

## TL;DR

KELT is a small robotic telescope designed for large-area sky surveys to detect planetary transits around bright stars, covering about 25% of the Northern sky with sufficient precision.

## Contribution

This paper introduces the hardware, software, and observational capabilities of KELT, demonstrating its effectiveness in detecting planetary transits.

## Key findings

- Achieves necessary photometric precision for transit detection
- Surveys 26x26 degree fields covering 25% of Northern sky
- Targets stars with 8<V<10 magnitude

## Abstract

The Kilodegree Extremely Little Telescope (KELT) project is a survey for planetary transits of bright stars. It consists of a small-aperture, wide-field automated telescope located at Winer Observatory near Sonoita, Arizona. The telescope surveys a set of 26 x 26 degree fields, together covering about 25% of the Northern sky, targeting stars in the range of 8<V<10 mag, searching for transits by close-in Jupiters. This paper describes the system hardware and software and discusses the quality of the observations. We show that KELT is able to achieve the necessary photometric precision to detect planetary transits around solar-type main sequence stars.
