Valentin D. Ivanov is a Bulgarian astronomer working in the European Southern Observatory, mainly at the Paranal site. Among his primary research areas are the dynamics of star clusters, formation of stars, brown dwarfs, and exoplanets around such objects.

Valentin Ivanov and Ray Jayawardhana are two of the pioneers of the investigation of the planemos, a special cast of exoplanets. They discovered the first double planemo Oph 162225-240515. This discovery, came just before the debate about the 2006 planet definition, and posed the problem about the distinction between planets and low-mass stars
