A colleague’s proposal on #exoplanets mass determination was evaluated as excellent, with no identifiable weaknesses… and yet got rejected. I am expecting an overcorrection next semester.
Been checking the science topics of the proposals approved by the ESO OPC for ESPRESSO. 75% of the time went to one type of proposal. Statistics-focused follow up of transiting systems. There isn't a single proposal focused on discoveries, atmospheres, or anything low-mass planets 🔭#exoplanets
