Radial velocities of HD 553
Listed in IVOA Registry (Virtual Observatory)
HD 553 was discovered as an eclipsing binary by Hipparcos.
Description
Here, we present the first radial velocity curve for this system. It is found, that HD 553 is a double-lined spectroscopic binary.
Despite the large luminosity difference, the two components of this system are of very similar mass. The primary, a K0-giant, fills a large fraction of its Roche-lobe. The secondary is, despite its very similar mass, still a late-type dwarf.

The radial velocity curve allows to constrain several stellar and system parameters.
