R31 - A massive O + W-R star binary in the Small Magellanic Cloud

Publications of the Astronomical Society of the Pacific, 1984
The authors present spectroscopic data on the O6 + WN3 binary R31 in the SMC, which improve the orbital determination of Moffat (1982). The period is found to be 6.538 days. From several considerations they consider an eccentricity of ≡0.2 to be possible.

Thermal stability of R218 (C3F8) and R31-10 (C4F10) under heat exposure

High Temperature, 2015
The results of study of the thermal decomposition of fluorocarbons under constant and cyclic heating are presented. Studies are carried out in the temperature range of 500–670°C. For continuous heating, the exposure time was 4 h; up to 106 cycles were carried out under cyclic heating.
