"It was discovered using data obtained with NASA�s Kepler Space
Telescope. Although Kepler was designed to find transiting planets,
Kepler-76b was not identified using the classical transit method of
detecting exoplanets."

actually I think it was the general theroy not the special

That's what I would've thought too, but just relaying what the article said.

#1 "Einstein's beaming effect" is primarily relativistic Doppler effect, which is Special.
#2 was the formation of a lobe, so gravitation and General.
#3 was reflected starlight, which is neither.

Since General includes Special as a special case, really no need to try and differentiate. Reporters rarely know enough to get this right.

I usually remember it by General = Gravity, Special = Speed.
