Outreach talk on exoplanets brought together schoolchildren from the area

The deadline for submitting name proposals for the extrasolar planet L 168-9b and its star L168-9 has been extended until Monday, November 28.

Within the framework of the “Name Exoplanets 2022” contest, this Thursday the dissemination event “Do you want to know how an exoplanet is discovered? to know his experience in what was the research that allowed the discovery of the extrasolar planet made up of L 168-9b and its star L168-9.

“The objective of disseminating science is that people can immerse themselves in it and that it not only stay within the scientific community, but the idea is to return knowledge to society. There are different ways to discover exoplanets and in the talk we focus on two: transit method and radial velocity method. The latter was the one that made it possible to discover the exoplanet and its star”, commented Astudillo.

It will be the bodies L 168-9b and its star L168-9, which will be nominated along with 20 exoplanetary systems that have better conditions to be observed by the James Webb Space Telescope (JWST). The foregoing through “Name Exoplanets 2022”, an initiative launched by the International Astronomical Union (IAU) and to whose call the UCSC joined by convening one of the teams led by Dr. Astudillo. Academics, university students, high school students, or those who wish to participate can still submit proposals, since the deadline has been extended until Monday, November 28.

“In science we are governed by the IAU, which lays the foundations for how celestial bodies are named: there are catalogs that have an acronym and then a number, so the names are ugly. So, it is a good opportunity to honor an idea by capturing it in the sky and naming a star, it is something very romantic, and I find that the citizens take that power very valuable”, said the researcher.

Among the aspects to consider for the assignment of a name are that they must be of things or places of long-standing cultural, historical or geographical importance. Although not required, the names can be drawn from topics related to the sky and astronomy, or related in some way to the constellation or a cultural asterism in which the exoplanetary system is located, or related to the properties of the exoplanet and its star . Two names should be proposed: one for the exoplanet and one for the star it orbits.
