The Trial Test
When starlight passes through the atmosphere of a planet, it interacts with nitrogen and carbon dioxide to produce distinct signals known as spectral lines. A modeling team produced simulated spectra for 20 versions of the planet TOI 700 d. This team is led by a Universities Space Research Association visiting research assistant at Goddard, Gabrielle Englemann-Sussia.
Gabrielle said that someday when they have actual spectra from the planet, they can backtrack and match them to the nearest simulated range and match that to the model. She called it exciting because whatever we are going to discover about TOI 700 d, it is going to be completely different from the Earth.
