ASTRON/RuG PhD student, Timo (Wing Hei Yiu) successfully defended his PhD thesis, "A radio study of extrasolar magnetospheres" on the 19th of May. The full thesis and the propositions can be found <a href="https://research.rug.nl/en/publications/a-radio-study-of-extrasolar-magnetospheres/">here</a>

Highlights of the PhD thesis include: (i) a detection of increase in radio emission efficiency at spectral type M4 where stars become fully convective and (ii) the first measurement of the magnetic field of a cold brown dwarf.

Well done, Timo! And best wishes for your future endeavors.
