Mikko Tuomi is a Finnish astronomer from the University of Hertfordshire, most known for his contributions to the discovery of a number of exoplanets, among them the Proxima Centauri b which orbits the closest star to the Sun. Mikko Tuomi was the first to find indications of the existence of Proxima Centauri b in archival observation data.[2] Other exoplanets to whose discovery or study Tuomi has contributed include HD 40307,[3] HD 154857 c,[4] Kapteyn c,[5] Gliese 682 c,[6] HD 154857,[4] Gliese 221,[7] Gliese 581 g[8] and the planetary system orbiting Tau Ceti.[9] He has led the development of new data analysis techniques for distinguishing observations caused by natural activity of the star and those caused by planets orbiting them.[10]
Publications
[edit]Mikko Tuomi has contributed to many cosmologist research articles including:
- "A Super-Earth in the Habitable Zone"[11]
- "Two planets around Kapteyn's star: A cold and a temperate super-Earth orbiting the nearest halo red dwarf"[12]
- "Bayesian search for low-mass planets around nearby M. draws. Estimates for occurrence rate based on global detestability statistics"[13]
- "A dynamically-packed planetary system around GJ667C with three super-Earths in its habitable zone"[14]
Discoveries
[edit]Mikko Tuomi helped discover the Proxima Centauri b planet by observing the gravitational tug of Proxima Centauri's star, Proxima Centauri.[2]
