Observations and analysis of the system R Canis Majoris.
BUDDING E. and BUTLAND R.
Abstract (from CDS):
Certain anomalous features of the system remain, however, in particular the combination of low period P and low mass ratio q. This may be related to the third body known to attend the close eclipsing pair, for which we also provide a new astrometric analysis and accompanying numerical results: M3= 0.8±0.1; R3= 0.83±0.07; L3= 0.4±0.1 (solar units). The `R CMa type', within the context of Algol evolution, may be seen as involving an unusually low q, P combination.
