研究代表者

LIVINGSTON JOHN・HENRY  東京大学, 大学院理学系研究科(理学部), 特任研究員 (60848555)

研究期間 (年度) 2020-04-01 – 2022-03-31
キーワードastronomy / exoplanets / transits / radial velocity
研究実績の概要

I have continued to develop transit and radial velocity analysis pipelines tailored for TESS data, as well as publishing in scientific journals, including the following recently submitted articles:
Hoyer, Gandolfi, Armstrong et al. (including Livingston), "TOI-220b: a warm sub-Neptune discovered by TESS", accepted to Monthly Notices of the RAS, arXiv:2105.01944
Georgieva, Persson, Barragan et al. (including Livingston), "Hot planets around cool stars -- two short-period mini-Neptunes transiting the late K-dwarf TOI-1260", submitted to Astronomy & Astrophysics, arXiv:2104.05653
Hirano, Livingston, Fukui et al., "Two Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions", submitted to The Astronomical Journal, arXiv:2103.12760

2: おおむね順調に進展している

理由

In addition to the publications listed above, several publications remain in progress. Furthermore, I have finished building several workstations for large scale data analysis, which I have begun using for analysis of data from the TESS mission.

今後の研究の推進方策

The plan for the future is to focus primarily on applying enhanced computational capabilities to more of the TESS data. The shift will thus be away from more traditional CPU-based analysis methods to large scale GPU-based analyses.
