David Brown

I am a postdoctoral researcher working in the field of extra-Solar planets. I gained my PhD in 2013 from the University of St Andrews, and before that studied Physics at the University of Warwick, graduating in 2009.

My current post is funded, in part, by the UK Space Agency; I am assigned to the upcoming PLATO mission as part of the Science Management Project Office. My time is split 50:50 between PLATO tasks and research into extra-Solar planets.

NOTE: I've recently moved offices within the department. Please check the office number and telephone number to the right.

Research

I'm interested in all aspects of exoplanetary science. My PhD was focused on the interactions between hot Jupiter planets and their host stars, particularly through gravitational tides. These can have a significant effect on the evolution of a planetary system, both from the star and the hot Jupiter's points of view. Current (and past projects) include:

  • Tidal spin-up of host stars
  • Tidal realignment of planetary orbits through measurement of the spin-orbit alignment angle using the Rossiter-McLaughlin effect
  • The accuracy of different stellar age estimation methods for exoplanet hosts
  • The presence of circumbinary planets in CoRot, Kepler, and K2 data
  • The existence, or otherwise, of additional, outer bodies in hot Jupiter systems that might have caused misalignment

Since beginning my PhD I have been part of the SuperWASP collaboration, and continue to work closely with the SuperWASP planet discovery and follow-up team. This includes working to identify new candidate planets, and radial velocity observations to pin down the masses of the planets. I am also an associate of the GAPS collaboration, am involved in several K2 follow-up collaborations, and work with several other members of the Warwick Astronomy group to investigate tidal decay of hot Jupiter systems.

PLATO

My work with the PLATO Science Management Project Office revolves around assisting the head of the PSM with the build-up to the mission. Since starting this position in 2015 I have assisted with two major ESA reviews, coordinated budget preparation and applications, and carried out efficiency and performance studies.

Copies of the conference talks (as well as some outreach talks) that I have given are availble on request. You will need a pdf viewer to open them.

Outreach

As well as research activities, I am very interested in public engagement and scientific outreach activities. I'm happy to talk to anyone about my research, or about what it's like working in astronomy; please feel free to get in touch if you'd like me to visit your group/society/meeting.

I have several pre-prepared talks, all of which can be adjusted to suit different time slots:

  • "A Brief History of Exoplanets" - an overview of major exoplanet discovery techniques and results; suitable for astronomy societies and older school groups.
  • "Falling Planets" - a more technical talk about tidal interactions; suitable for astronomy societies.
  • "Exoplanet Hunting: the life of a professional astronomer" - an overview of my inspirations and career path, with the basics of exoplanet discovery; suitable for schools and youth groups.

Leisure

In my spare time I rehearse and perform with the Leamington Sinfonia orchestra as part of their woodwind section.

I also swim regularly, and am very interested in water safety. I've been a member of the RLSS for over ten years, and am both a qualified lifesaving instructor and first aider. I also regularly compete in and judge at lifesaving competitions.
