A gas wind in our Solar System
Thanks to ALMA, we now know that gas around exo-Kuiper belts is common (it is the rule rather than the exception to have gas in bright planetesimal belts). The question we are trying to answer in our paper is whether gas should be present in our Kuiper belt as well and in which quantity?
We use the knowledge from all gas observations in exoplanetary systems and the models that were developed to explain them in the last decade to assess the quantity of gas that should be pres
