Research and Spectral Libraries

Jupiter observed in near-infrared wavelengths shows bright bands, and spots that are analogs as those expected for brown dwarfs

My research focuses in the characterization of the atmospheres of low-mass stars, brown dwarfs and free-floating planets.

My spectral libraries

Xshooter, ISAAC and HST Spectral libraries as published in Manjavacas et al. (2014, 2016, 2019, 2020)
