Abstract

We have developed a set of custom narrow-band filters for the twin multiband imagers MuSCAT3 and MuSCAT4 on the 2m telescopes of Las Cumbres Observatory. These filters are designed to detect sodium absorption in the atmospheres of hot Jupiters by means of multiband transit photometry. One of the filters is designed to observe the sodium doublet lines at 589.3 nm, while the others are optimized to measure the continuum of the transmission spectra, avoiding absorption and scattering by the Earth’s atmosphere. A pilot observation of a transit of the hot Jupiter WASP-104 b demonstrated the good performance of these custom narrow-band filters. This filter set enables an efficient survey to search for cloudless hot Jupiters, which can be prime targets for further atmospheric characterizations with space- and ground-based high-demand telescopes.
