The other noteworthy thing is that we see clear evidence of hydrocarbons (methane at 7.7 microns and ethylene at 10.5 microns) in the MIRI portion of the spectrum. This is the smallest object with hydrocarbons detected in its disk!

We calculated an accretion rate based on these lines, and this object is accreting way more than "typical" objects of its mass. We're not sure why.

Our object, Cha 1107-7626, is part of the Chameleon star forming region, which is why we have an estimate of its age of 1-3 Myr. And the accretion signatures were not a surprise. Prior published spectra also showed lots of emission from H-alpha and P-beta.
