Magnetic activity and the formation of stars and planets

News & Research

Welcome to my homepage! You'll find an overview of the research that I am doing, as well as research from other groups that has grabbed my attention [much more research content coming soon...]. I work with some fun and very active graduate students here at ESO, you can find a little more about them here too - as well a very brief summary of my career to date.

Press Release (Sep 2015)

First hint of a planet around a very young star!

Group & Visitors

PhD students

  • Julian David Alvarado Gomez: (IMPRS/ESO/LMU, final year)
  • Expert in the characterisation of magnetic activity and the coronae of slowly rotating (solar-type) and planet-hosting stars. Experience in the tomographic technique of Zeeman Doppler Imaging and modelling coronae and space weather in stellar systems using the 3D MHD BATS-R-US codes, part of the Space Weather Modeling Framework.

  • Logithan Kulenthirarajah: (Home Inst: IRAP/OMP, France, first year)
  • Characterising the spectra of M dwarfs in the optical and NIR and studying the effects of strong magnetic fields.

  • Alexis Lavail: (Home Inst: Upsala, Sweden, second year)
  • Member of the CRIRES upgrade team. Experienced in reducing NIR high resolution spectra and currently measuring the magnetic field strengths in young (T Tauri) stars over a wide range of masses.

  • Belinda Nicholson: (Home Inst: USQ, Australia, second year)
  • Experienced in modelling the coronae of planet-hosting cool stars and currently mapping magnetic fields in young pre-main sequence stars using HARPS spectropolarimetric data.
