A far greater number of spectra were gathered for HAT-P-33 than the number usually gathered for planetary candidates to compensate for the data's jitter effect. It was concluded that the jitter in the data was caused by stellar activity and not the presence of other planets. 713:
planet's defined characteristics are based on the assumption that HAT-P-33b has an elliptical orbit, although the planet's discoverers have also derived HAT-P-33b's characteristics on the assumption that the planet has a circular orbit. The elliptical model has been chosen because it is considered to be the most likely scenario.

The planet is about three-fourths the mass of Jupiter, but is almost eighty percent larger than Jupiter is; this inflation has, as with the discovery of similar planets 712:
The best fit for the shape of HAT-P-33b's orbit suggests that the orbit is slightly elliptical, as the planet's orbital eccentricity is fit to 0.148. However, because the star HAT-P-33 has such a high level of jitter, it is difficult to constrain the planet's eccentricity with accuracy. Most of the

Because high levels of jitter have been detected in the spectrum of HAT-P-33, the ability to collect the most sensitive radial velocity measurements possible has been dulled. The loss of accuracy has prevented astronomers from disregarding the possibility that HAT-P-33 is actually a binary star,

where the secondary, dimmer companion is visually indistinguishable from the brighter primary companion. If this is the case, then the dimmer star in the HAT-P-33 system would have to have a mass that is less than 0.55 times that of the Sun. A search for a binary companion star using
