Name ExoWorlds Event Announcement
A press conference to present the official results of the NameExoWorlds campaign to name more than 100 exoplanets and host stars by the International Astronomical Union (IAU) will be held on Tuesday, 17 December 2019 at 6 pm (Brunei Time) from Observatoire de Paris, Salle Cassini.
A live broadcast of the session is available via Youtube https://www.youtube.com/watch?v=we4E8Yuc0Nc
NameExoWorlds Brunei Darussalam
Currently there are a total of more than 4,000 confirmed planets that orbit stars outside the solar system known as exoplanets. Most of these exoplanets have no proper names. An initiative by the International Astronomical Union (IAU), NameExoWorlds offers the opportunity for all countries in the world including Brunei Darussalam to give a name to one exoplanet and its hosting star. Names will be chosen by public voting carried out in each country. The chosen names will be recognized by IAU as official names. A national committee for Brunei Darussalam will organize this campaign from August 2019 onwards.
- To provide opportunity for people of Brunei Darussalam to name exoplanet and its star.
- To raise public awareness on the existence of the planetary system outside our solar system.
- To promote astronomy especially Islamic astronomy (Falak Syarie) and space science in Brunei Darussalam.
Ten shortlisted NameExoWorlds Brunei Darussalam proposals:
|Star HD 179949||Exoplanet HD 179949b||Theme|
Assigned Planetary System for Brunei Darussalam
Star Identification: HD 179949
Type: yellow-white, dwarf
Brightness: 6.25 magnitude
Surface Temperature: 6250 K (500 degrees hotter than the Sun)
Mass: 1.25 x sun
Distance from the Earth: 88 Light Years (8.3254 x 1014 km)
Spectral Class: F8 V
Description: HD 179949 is a sixth magnitude (6.25) class F8 dwarf star in Sagittarius. From a distance of 88 light years, it shines with a huminosity 1.8 times that of the Sun from a surface with a temperature of 6250 Kelvin, almost 500 degrees hotter tn the Sun. From these values, we infer a radius 1.16 times solar, a mass 1.25 solar, and that the star is very young. Like most planet-holding stars, it is metal-rich, with an iron content (relative to hydrogen) that is 65 percent greater than the Sun.
ExoPlanet Identification: HD 179949 b
Planet Type: Gas Giant
Discovery date: 2000
Mass: 0.916 Jupiter
Planet radius: 1.24 x Jupiter (estimate)
Orbital Radius: 0.0443 AU
Orbital period: 3.1 days
Detection Method: Radial Velocity
Description: HD 179949 b is a gas giant exoplanet that orbits a F-type star. Its mass is 0.916 Jupiters, it takes 3.1 days to complete one orbit of its star, and is 0.0443 AU from its star. Its discovery was announced in 2000.
