Nitrogen-containing Anions and Tholin Growth in Titan's Ionosphere: Implications for Cassini CAPS-ELS Observations
The Cassini Plasma Spectrometer (CAPS) Electron Spectrometer (ELS) instrument onboard Cassini revealed an unexpected abundance of negative ions above 950 km in Titan’s ionosphere. In situ measurements indicated the presence […]

Seasonal Evolution of Temperatures In Titan's Lower Stratosphere
The Cassini mission offered us the opportunity to monitor the seasonal evolution of Titan’s atmosphere from 2004 to 2017, i.e. half a Titan year. The lower part of the stratosphere […]

Evidence of Changing Seasons And Rain On Titan's North Pole
An image from the international Cassini spacecraft provides evidence of rainfall on the north pole of Titan, the largest of Saturn’s moons. The rainfall would be the first indication of […]

A possible deep CH4 reservoir in Titan, Super-Titan exoplanets and moons
We investigate the thermal equation of state, bulk modulus, thermal expansion coefficient, and heat capacity of MH-III (CH4 filled-ice Ih), needed for the study of CH4 transport and outgassing for […]
