Give the name of the star and exoplanet in the system HAT-P-3

In celebration of the 100th anniversary, the International Astronomical Union (IAU) organizes the IAU100 NameExoWorlds contest, in which each country on Earth is allocated its own system and is given the opportunity to name the exoplanet and the star around which it rotates.

The approved names will not replace the traditional scientific designations, but will be recognized by the IAC as full names of the objects, will be published in this capacity with the indication of authorship. These names can then be used by everyone, without any restrictions, along with or instead of scientific designations.

The distribution of the planets by country was made on the basis of the possible presence of cultural ties or taking into account the visibility from most of the territory.

Russia allocated system HAT-P-3



Orange dwarf HAT-P-3 is located in the constellation Ursa Major at a distance of 456 light years from Earth.

The dwarf is a star quite young by astronomical standards - its age is estimated at 400 million years.

At least one exoplanet rotates around the orange dwarf - HAT-P-3b.



Planet HAT-P-3b is a gas giant weighing about 0.65 of the mass of Jupiter:
- was opened in 2007;
- surpasses Earth by 75 times;
- its core consists of heavy elements;
- its atmosphere is heated to ultra-high temperatures,
- The duration of the year on the HAT-P-3b is 2.9 days.

How the HAT-P-3 system looks like can be viewed on the NASA website - the images of exoplanets on this resource are more hypothetical, but an interesting idea for their name can come even based on such pictures.

After all, in this competition you need to show imagination and “finish” the image of the planet and system in your head.

In Russia, the deadline for applications is September 30, 2019.

Then within two weeks the national committee will select the applications for voting.

Voting will be held from October 15 to November 15, after which the national committee will submit one winning option, two reserve options and all voting results to the IAU100 steering committee NameExoWorlds for approval.

The steering committee may reject the results if the selected names do not comply with the rules of the IAC or if the number of applications and / or votes cast is too small. Final results are expected to be announced in the second half of December.

Names may belong to objects, people, or localities that have a large and long-lasting cultural, historical, or geographical significance that deserve perpetuation in the name of a celestial object.

The application should be offered two names at once - for exoplanets and for the parent star, which should be linked by a common theme.

In addition, a brief description of the topic that logically connects the proposed names should be added to the application.

Offensive names or names analogous or similar to already existing names of celestial objects, names with a commercial meaning, names of people who are known for their political, military or religious activities, names of people who died less than a century ago, names of living people, names of organizations, names pets, specially coined names, abbreviations, names containing numbers or punctuation marks (accented letters are allowed).

What other systems other countries have been chosen by the MAS can be found here .

For example, for the United States they chose the HD 17156 system (in the constellation Cassiopeia), 245 light years from Earth.



For Estonia, they chose the XO-4 system (in the constellation Lynx), 956 light years from Earth.



If you live in a country that has not yet launched a naming campaign, its representatives must confirm participation in the competition - do so before June 30, 2019, by filling out forms on the IAC website .
