Long-Term Ground-Based Monitoring of the Venusian O₂ Nightglow Open
Airglow emissions in the upper atmosphere of Venus offer valuable tracers for probing atmospheric dynamics between 90 and 120 km. The 1.27 μm O₂ airglow, which contribution function is near 95 km altitude, is particularly useful as it lies…

Titan’s Ultraviolet Airglow Variability with Solar Cycle and Saturn Local Time Open
The Cassini spacecraft observed Titan’s upper atmosphere and its airglow emissions from 2005 to 2017. It is now established that the solar XUV radiation is the main source of dayglow, while magnetospheric particle precipitation princ…

Enhanced Airglow Signature Observed at Titan in Response to its Fluctuating Magnetospheric Environment Open
On rare occasions Titan has been observed in the magnetosheath, where the solar wind interferes with the regular magnetic field generated by Saturn. This particular orbital position allows for a deeper investigation of Titan's upper atmosp…

Variability of the nitric oxide nightglow at Venus during solar minimum Open
We present results from a NO airglow inversion method based on Venus Express data acquired from 2006 to 2010, during the last solar minimum period. We retrieve an altitude of 114 ± 10 km for the emission peak of the NO layer, with an assoc…
