NameExoWorlds

IAU100 NameExoWorlds Contest

For the second time in its history, the International Astronomical Union (IAU) has been organizing a competition for the names of the planets and stars around which they rotate ( http://www.nameexoworlds.iau.org/). This time, project participants dedicated to the 100th anniversary of the founding of the IAU are invited to give names to systems containing one star and one planet, with each country being allocated its own system. It is important to understand that approved names will not replace traditional scientific designations, but will be recognized by IAU as full names of objects and published with authorship. These names can then be used by anyone, without any restrictions, alongside or instead of scientific notation.

The HAT-P-15 planetary system in the constellation of Perseus is allocated to Ukraine. The star in this system is a yellow dwarf (type G) and is not yet accessible to ground-based telescopes. Exoplanet HAT-P-15b was opened in 2010 and is at a distance of 0.0965 AU. from the star, is a giant gas planet with a mass of 1.94 masses of Jupiter and an orbital period of 10.9 days (https://exoplanets.nasa.gov/exoplanet-catalog/1229/hat-p-15-b/).

 

Given the wide public resonance of the contest, the worldview of the proposed names for the planetary system that will perpetuate our choice, the National Committee urges all organizations to place this information on their web pages and keep it active until the end of the contest, and to disseminate it to all social networks.
