Thermal Structure of a Protoplanetary Disk around HD 163296: A Study of Vertical Temperature Distribution by CO Emission Lines
This paper presents observations of a protoplanetary disk around the Herbig Ae star HD 163296 in $^{12}$CO ($J$$=$ 1–0), $^{12}$CO ($J$$=$ 3–2), $^{13}$CO ($J$$=$ 1–0), and $^{13}$CO ($J$$=$ 3–2) emission lines. Double-peaked emission profiles originating from the rotating circumstellar disk were detected in all of the lines. The disk parameters …
