Scientific paper

An analysis of recent observations of RY Sgr has shown that the times of light maxima can no longer be represented by a quadratic solution where the pulsation period decreases linearly with time. A cubic solution gives a better fit to the data, but a series of linear piecewise solutions satisfy the O-C residuals to within the observational uncertainty. It is believed tht the latter interpretation provides a more astrophysical explanation. Finally, a likely mass for the R Coronae Borealis (RCB) stars of about 0.7 solar masses has been derived from observations of the RCB stars in the Large Magellanic Cloud.
