5. Conclusions

In this paper we report new determinations of the radius ([FORMULA]) and mass ([FORMULA]) of the pulsating hydrogen-deficient star LSS 3184. The radial velocity data and temperature measurements are more reliable than those used for previous radius and mass determinations for this star, so our estimates are likely to be closer to the star's actual parameters. Further improvements can be accomplished by improving the [FORMULA] and chemical composition estimates for LSS 3184. In addition, there needs to be further study of the difference between the shapes of the angular radius and physical radius curves based on temperature and flux measurements, and radial velocity measurements, respectively. It is important to determine if the difference in shapes is a sign that some of our data or a step in our analysis is flawed, or if there is something happening in the star itself that causes the two measures of radius to behave differently with pulsational phase.
