Velocities and light curves of V350 Sgr
Listed in IVOA Registry (Virtual Observatory)
"The Cepheid Mass Problem" is one of the fundamental tests of the understanding of stellar evolution.
Description
One of the foundations of measured masses for Cepheids for this question is binary orbits. V350 Sgr is a classical Cepheid in a binary system.
New radial velocity data for the system have been obtained over the last several years, and are used to update the orbit. The secondary in the system has previously had its orbital velocity amplitude measured in the ultraviolet with the Hubble Space Telescope. This amplitude has been combined with the new orbit and the adopted mass of the secondary resulting in a Cepheid mass of 5.0+/-0.8M_{sun}_.
