DESCRIPTION:Up to date more than 4\,000 known exoplanets have been detected
 . The characterization of their atmospheres is a natural step to learn mor
 e about their diversity especially from the atmospheres of rocky exoplanet
 s. They can potentially host bio-signature gases\, notably molecular oxyge
 n (O2). When observed through transmission spectroscopy\, it is possible t
 hat the star-planet configuration allows us to sample only low pressure la
 yers\, and therefore the absorption lines will be very narrow\, and we wil
 l need extreme high resolution to fully resolve the lines. Higher resoluti
 on allows us to disentangle actual signal and telluric lines in our own at
 mosphere. Recent studies show that O2 is best observed from ground with up
 coming Extremely Large Telescopes. The spectral resolutions of 300\,000 - 
 400\,000 are optimal to detect O2 in the atmosphere of an earth analog. Ho
 wever\, typical high-resolution spectrographs have resolutions around 100\
 ,000. In order to increase detection capabilities\, we have developed a Fa
 bry Perot Interferometer for Oxygen Searches (FIOS)\, an interferometer ar
 ray coupled to a high-resolution spectrograph. FIOS can achieve a spectral
  resolution of 500\,000 at the O2A-band (760 nm). I will describe the inst
 rument concept\, a simulation of its sensitivity\, and preliminary results
  from our lab prototype. https://astronomia.uc.cl/2jucext1/institutoastrof
