Orbital elements of the exnova CP Puppis

Radial velocity measurements of the exnova CP Pup yield an orbital amplitude of 92 km s−1 and a period of 0.061 4215 day, which is shorter than the photometric periods determined by Warner. The mass of the secondary is 0.14 M⊙, that of the primary is below 0.86 M⊙, perhaps as low as 0.12 M⊙.
