Example Sentences

"We found that the temperature has the strongest effect on both the relative shapes of the evening and morning spectra as well as their relative offset," the authors explain, adding that clouds also became more or less opaque as temperatures adjusted.

From Salon

"For example, more detailed cloud or haze models, especially ones focused on specific species, may affect the shapes differently or even induce relative slopes across the spectra. Disentangling these details will require more observations over a wider wavelength coverage as well as much more complex multi-dimensional modelling. Nevertheless, our results show that recovering the separate properties of a transiting exoplanet’s morning and evening terminators is possible, and that WASP-107 b exhibits significant morning-to-evening asymmetry."

From Salon

Astronomers can tell whether there’s a black hole in the galaxy by looking at large emission lines in their spectra, created by gas around the black hole swirling at high speed.

From Salon

The information astronomers have collected so far from the Little Red Dots’ spectra and emission lines has led to two diverging models explaining their nature.

From Salon

Radio waves are the main footprints of these disks, and by studying the spectra of a disk, astronomers can understand a lot about what they are made of and how planets really form.
