First Detection of Submillimeter-wave [13C i] 3P1-3P0 Emission in a Gaseous Debris Disk of 49 Ceti with ALMA

We have detected the submillimeter-wave fine-structure transition (3P1-3P0) of 13C, [13C i], in the gaseous debris disk of 49 Ceti with the Atacama Large Millimeter/submillimeter Array (ALMA). Recently, the [C i] 3P1-3P0 emission has been spatially resolved in this source with ALMA. In this data set...
