" For 10 points, name these bodies that orbit a star that isn't the Sun.
Butler and Marcy of San Francisco State University pioneered the study of these objects. The presence of one of these objects creates an additional Römer delay in the frequency of a pulsar. Types of these objects characterized by gas have been detected by the OGLE project. Examples of these objects with large masses and extremely short periods are characterized as (*) "hot." Common ways of detecting these entities include gravitational microlensing and using photometry in conjunction with a transit. The Kepler mission seeks to find these objects. Types of these entities that may feature liquid water on them lie in a "habitable zone." For 10 points, name these bodies that orbit a star that isn't the Sun.

extra-solar planets [or exoplanets, accept "Jupiters," "Jovian exoplanets," and similar answers due to the "hot" clue]
