Resolving protoplanetary Hα emission with the high-resolution spectrograph RISTRETTO
Thousands of exoplanets have been discovered to date, but only a handful of them are young planets in the later stages of their formation. Hα emission is a strong tracer of this process, but it is difficult to isolate the planetary Hα signal from the stellar signal due to the small angular separatio...
