Abstract

In this concept study, we are targeting to build a new instrument to sequentially observe exoplanet atmospheres and their parent's stellar spectra over a significant time in NUV and FUV. The Compact Homodyne Astrophysics Spectrometer for Exoplanets (CHASE) offers integrated spectra over a wide field-of-view (FOV∼40arcsec) in high spectral resolution (R>105) in a miniaturized architecture using no (or a small < 1m) primary mirror. CHASE's wide FOV is compatible with the relaxed pointing requirements of current CubeSats and SmallSats which makes it readily qualifiable for space in a compact format and have the potential to enable major scientific breakthroughs.
