Titan harbors a dense, organic-rich atmosphere primarily composed of N$_2$ and CH$_4$, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 ($\sim$230-272 GHz), we obtained the first spectroscopic detection of CH$_3$C$_3$N (methylcyanoacetylene or cyanopropyne) in Titan's atmosphere through the observation of seven transitions in the $J = 64\rightarrow63$ and $J = 62… Expand

No phosphine in the atmosphere of Venus
The detection of phosphine (PH₃) has been recently reported in the atmosphere of Venus employing mm-wave radio observations (Greaves et at. 2020). We here demonstrate that the observed PH₃ featureExpand

Abstract Observational data of Titan's atmosphere composition, gathered in particular by the Cassini mission, allow accessing latitudinal, longitudinal and temporal variations of the altitudinalExpand
Chemical changes induced during heating of acetonitrile-rich ice pre-irradiated by X-rays and its implication in astrochemistry.
It was verified that acetonitrile has a thermal desorption peak between 120 K and 200 K, which yields to the vanishing of acetonrile within the sample for temperatures of 200  K and above, which indicates the presence of blended species with similar infrared features. Expand
Science Goals and Objectives for the Dragonfly Titan Rotorcraft Relocatable Lander
