Olivier Chesneau Explained

Olivier Chesneau (1972 in Mozé-sur-Louet – May 17, 2014 in Nice^[1]) was a French astronomer.

He contributed to a better understanding of several aspects of evolved stars physics, especially planetary nebulae, massive stars and novae.

Among other discoveries, Olivier Chesneau discovered the "peanut star" HR 5171,^[2] the fact that novae explode with an hourglass shape already a few days after outburst (e.g. RS Ophiuchi^[3]), or the detection of disks in the heart of planetary nebulae.^[4]

The Laboratoire J Lagrange at the Côte d'Azur Observatory in France, and ESO established a prize in his memory, The Chesneau Prize.^[5]

Minor planet 6065 Chesneau is named in his honor.^[6]
