Whenever it passes in front of a star, Pluto provides precious information about its atmosphere, precious because occultations by Pluto are rare. The survey achieved by researchers from Paris Observatory over several decades of observations appears in the journal Astronomy and Astrophysics of May 10, 2019. Interpreted in the light of data collected in 2015 by the probe New Horizons, it allows them to refine physical parameters that are essential for a better understanding of Pluto’s climate and to predicting future stellar occultations by the dwarf planet.
