Abstract

fetched live from OpenAlex

The purpose of this project is to create an accurate fitting function for transiting stars. Data from these transiting stars will ultimately be used to identify new exoplanets. It is very apparent that a fitting function that addresses multiple environmental parameters affecting brightness measurements is needed as exoplanet identification can be a cumbersome and time consuming process. Utilising computer code will streamline the process of exoplanet identification and can then allow researchers to focus their energies solely on data collection. It should be duly noted that in order to collect data from transiting stars; one can use amateur equipment but, for the sake of maximum accuracy; a high powered telescope would be more suitable (“Exoplanet Transit Parameters”, 2008). Previous students at MacEwan that collected transiting star data utilised the Athabasca University Robotic Telescope (AURT) (“Defining the Transit Method”, 2017). This telescope requires booking periods thus, in order to maximize utility and efficiency; more energy should be spent on data collection and result analysis. The current state of exoplanet discovery is both innovative and exciting. In fact in February of 2017, a team of astronomers at the University of Liege in Belgium discovered four more Earth-sized exoplanets (bringing the total up to seven) orbiting Trappist-1 which is a star that is classified as an ultracool dwarf (“Astronomers Discover”, 2017). Another discovery would be that of Proxima b, the exoplanet that is closest to our solar system (“An Earth-like Atmosphere”, 2017). Astronomers are currently debating whether or not Proxima b will be able to sustain life. Thus, it can be shown that exoplanet discovery and analysis yields results and is vital for our understanding of the universe. Works Cited Garner, R. (2017, July 31).

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
