Boonrucksar Soonthornthum

About

Boonrucksar Soonthornthum is a leading Thai astronomer whose research centers on binary star systems and astronomical instrumentation. His most cited work, "RW Doradus: A solar-type shallow contact binary with a new orbital period investigation" (2019, 13 citations), presents new CCD photometric light curves of the short-period eclipsing binary RW Doradus, observed using the PROMPT-8 robotic telescope in Chile and the 2.15 m JS telescope at CASLEO. This study contributes critical insights into the orbital dynamics and evolution of solar-type contact binaries. Soonthornthum is also a key figure in the development of advanced observational tools for the 2.3 m Thai National Telescope. His paper "Opto-mechanical design and development status of an all spherical five lenses focal reducer" (2016, 4 citations) details the creation of a focal reducer that images a 14.6-arcminute field of view with a pixel scale of 0.42 arcseconds per pixel and spatial resolution better than 1.2 arcseconds. As a core member of the National Astronomical Research Institute of Thailand (NARIT), his work bridges stellar astrophysics and cutting-edge instrumentation, enabling high-resolution studies of variable stars and exoplanetary systems.
