Lagrange's work focuses on the research and study of extrasolar planetary systems. From the 1990s, she began to search for exoplanets using direct imaging using novel adaptive optics. In the 2000s, her research became focused on the study of giant planets around young stars. In 2005, she made the first direct observation of an exoplanet around a brown dwarf using deep adaptive-optics. Lagrange also investigates the impact of stellar activity on the detectability of planets.[1][2] Lagrange is the holder of numerous scientific awards and honorary decorations, including knight of the Legion of Honour (the highest French order of merit) and is a member of the French Academy of Sciences since 2013. Discovery of exoplanet Beta Pictoris bLagrange has devoted much of her career to the analysis of the star Beta Pictoris in the constellation Pictor. During her thesis in the 1980s, she studied the disc of debris that had just been discovered around this star. Several elements indicated the presence of a massive planet, but the scientific community remained skeptical.[4][5] However, in the 2000s, Lagrange made several observations of the debris disc using adaptive optics coupled with direct imaging using a near-infrared spectrometer mounted on the Very Large Telescope (VLT) of the European Southern Observatory (ESO). On November 18, 2008, after processing the data taken in 2003 using reference star differential imaging and modern image processing tools, Lagrange discovered the exoplanet Beta Pictoris b orbiting around the star, confirming her earlier predictions.[2][6] PrizesLagrange has received a number of prizes during her academic career including:[4][7]
