These objects, along with brown dwarfs, can be detected with Doppler spectroscopy.
The infrared spectra of cold examples of these are dominated by methane, while hot spectra contain signatures of water. Queloz and Mayor discovered one of them around 51 Pegasi, and the first discovery of these objects was made around a pulsar. These objects, along with brown dwarfs, can be detected with Doppler spectroscopy. The TESS mission intends to study nearby ones, which can be detected by observing dips in stellar light curves in the transit method. In July 2015, one of these named Kepler 452b was announced as Earth's "bigger, older cousin." For 10 points, name these objects, including "hot Jupiters" and "super Earths," that orbit stars other than our Sun.
