Chemical equilibrium in AGB atmospheres: successes, failures, and prospects for small molecules, clusters, and condensates
Chemical equilibrium has proven extremely useful for predicting the chemical composition of
AGB atmospheres. Here we use a recently developed code and an updated thermochemical …

Discovery of two new magnesium-bearing species in IRC+ 10216: MgC3N and MgC4H
We report on the detection of two series of harmonically related doublets in IRC+ 10216.
From the observed frequencies, the rotational constant of the first series is B= 1380.888 MHz …
